Meet DinoX

DinoX lets you send messages, share pictures and files, and make voice and video calls. You need an XMPP account. XMPP connects different providers: you and your contacts do not have to use the same provider.

Your XMPP address is technically called a JID, for example bob@dinox.im. It looks like an email address, but belongs to a chat account. You can only use an existing email address if your provider has explicitly created an XMPP account with that same address. Your email password does not automatically work in DinoX.

The pictures show real DinoX windows with demo accounts. Enter your own details. Colours, window controls and available features can vary with your operating system, package and server. Select a picture to open the larger view.

Bob and Anna are examples in this guide. Enter your own XMPP address during setup and ask contacts for theirs. The demo accounts shown are not support addresses.

01 · Getting started

Install the right package

Choose a package that matches your operating system. A .deb filename does not mean that the package works on every Debian-based distribution.

AppImage and Flatpak are not tied to the Debian or Ubuntu package manager. They are also intended for other Linux distributions, including Fedora and openSUSE with RPM packages. You do not convert them to RPM. Matching processor architecture and system requirements still matter; this DinoX package has not been tested on every older distribution.

Flatpak support must be installed, and the required runtime is installed separately. An AppImage starts directly as an executable file but still needs basic system libraries. A DEB must match the stated distribution and version.

What do the choices mean?

Windows

Extract the whole ZIP. Keep the extracted folder together and open dinox.exe inside it. Do not move the EXE on its own: it needs the other files.

Ubuntu 24.04 / Linux Mint 22

Install the DinoX DEB with your package manager. From the download folder you can also use: sudo apt install ./dinox_2.3.2_amd64.deb. APT obtains required libraries from your configured repositories.

Debian 13 based on Trixie

Use AppImage or Flatpak. The Ubuntu DEB requires different library versions. Do not try to bypass missing libgpgme11t64 or libicu74 with development packages, Ubuntu repositories or a forced installation.

AppImage

Allow the file to run as a program in its file properties, then open it. The additional .sources.tar.xz archive is not needed to run the application.

Flatpak

Open the .flatpak file with a Flatpak-capable software manager, or install it with flatpak install --user ./dinox-2.3.2-x86_64.flatpak. Flatpak also installs the required runtime. Its local data is separate from DEB and AppImage.

Understand the two passwords

The first password protects DinoX data on this computer. It is not your XMPP account password. It covers the accounts you set up in this local DinoX data directory.

Keep this password safe. Reinstalling cannot unlock data protected by a forgotten password. Make a backup before resetting data or moving to another computer.

Take care during normal unlocking: after three failed attempts, this version triggers a local emergency wipe. Do not repeatedly guess the password. The special unlock flow after a restore is exempt.

What to do

1. Enter a password you can keep safe in both fields.
2. Choose “Set Password”. Use this password to unlock DinoX on later launches.

Choose or create an account

Already have an XMPP address? Choose “Sign in”. If not, choose “Create account” and select a provider. You do not need to follow both routes.

The sign-in dialog also offers “Create account”. “Restore from Backup” is for an existing DinoX backup; it does not register a new account.

01 · Getting started

Sign in to an existing account

Enter the complete address, including the part after @. Your account password was provided by your XMPP provider or set by you there. A display name such as “Bob” is not enough to sign in.

What to do

1. Enter the XMPP address and this account’s password.
2. Normally leave “Advanced Settings” closed. Only use details supplied by your provider or administrator there.
3. Choose “Login” and complete the success screen. If an error remains, check the address, password and internet connection.

01 · Getting started

Create an account with a provider

The provider operates your account’s server. It manages sign-in, availability and possibly message history. Choose a provider whose terms and service suit you. The list in DinoX is a selection, not a guarantee of free or permanently available registration.

What to do

1. Select a listed provider or search for its domain.
2. Complete the displayed form. The provider determines required information and checks.
3. If DinoX directs you to a website, finish registration there. Then sign in to DinoX with the complete XMPP address you received.
4. Keep the address and account password safe. Then add a contact.

01 · Getting started

Find your way around the main window

Open conversations are listed on the left; the selected chat appears on the right. In a narrow window DinoX shows these areas one at a time. Use the back button to return to the list.

The three horizontal lines open the application menu. The three vertical dots in a chat open that conversation’s menu. These two menus have different purposes.

In these captures, Close, Minimize and Maximize are at the top left of the main window. Small dialogs may have just their own close button. Cancel ends the current operation, not the whole application.

What do the choices mean?

Single person

Start a conversation with a contact or add a contact.

Group of people

Open saved groups, join a group or add a group.

Invitation

Create an invitation when supported by your account and server.

Speech bubble / status

Set your presence status. This is separate from muting an individual chat.

Connection symbol

View connection status and open connection options.

Main menu

Settings, feeds, keyboard shortcuts, application information and updates. Panic Wipe is a separate deletion function, not the normal way to quit.

02 · Contacts & chats

Add a person and open the chat

To write to someone, you need their complete XMPP address. An alias is your own name for this contact. It does not change their address.

What to do

1. Select the single-person icon at the top left.
2. Choose “Add Contact” at the bottom of the selection window.
3. If you have several accounts, first choose your own account for this contact. Then enter the address and optionally an alias.
4. Choose whether to share your online status, then select “Add”.
5. Select the contact in the list and choose “Start”. Before the first message, check the lock beside the message field.

02 · Contacts & chats

Find an address in a server directory

This is not a worldwide people search. It works only if your server offers a searchable directory and your account is connected. The server controls the available fields and results.

What to do

1. Open the search from the contact form and fill in the available search fields.
2. Choose a matching result and check the address copied into the contact form.
3. Only “Add” saves the contact. If no directory is available, ask the person for their complete address and enter it directly.

02 · Contacts & chats

What does a contact request mean?

This concerns your online status: may this person see whether you are available? Accepting the request does not determine whether messages use OMEMO, OpenPGP or no end-to-end encryption.

You can accept or decline the request. Check the address if you do not recognise the person. Sharing online status can also determine access to an XMPP feed restricted to contacts.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

02 · Contacts & chats

Send your first message with OMEMO

OMEMO is normally the default for new conversations unless you changed this account’s default. Check the actual choice at the lock. OMEMO encrypts messages for the devices of the people involved.

Contact permission alone is not enough: devices need to supply the necessary keys. If DinoX reports missing or unaccepted keys, open the contact’s encryption page. Do not switch to unencrypted messages just to bypass that notice.

What to do

1. Select “OMEMO” at the lock, or check that it is already selected.
2. Type your message at the bottom. Enter sends it; Shift+Enter inserts a line break.
3. After sending, check the message state. Sent, delivered and read are different states; a read receipt appears only when supported and allowed.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

02 · Contacts & chats

Organise, mute and remove contacts

Conversation Details contains information about this contact and chat. “Preferences → Contacts” manages contacts across your accounts. Read the confirmation text before any removal.

What do the choices mean?

Pin and mute

Pinning keeps the chat near the top of your list. Muting suppresses notifications; messages can still arrive.

Bell and privacy

Use the bell to choose notifications for this chat. Details also provides per-chat typing notifications, read receipts and retention settings.

Edit alias

Set your own display name for the contact in contact management. This does not change their XMPP address.

Block

Blocking one contact differs from blocking their entire domain. A domain block also affects other people at that provider. Remove the block to undo it.

Remove contact

Removing through chat details or contact selection also removes the history stated in that confirmation. The bin under Preferences → Contacts preserves history. “Close Conversation” only removes the open chat from the list.

02 · Contacts & chats

Work with messages

Actions depend on whether the message is yours, its type and support at the other client. Open actions on the message you want to work with.

What do the choices mean?

Reply

Choose Reply, check the reference and type below. This identifies the message you are answering.

React

Choose an emoji on the message. Other clients need to support displaying reactions.

Edit

Choose Edit on your own message, change the text and finish. Editing does not guarantee the old text has disappeared everywhere.

Copy text

Select text and use the offered copy action to copy it to the clipboard. If you paste it into another chat, check the destination before sending.

Delete

Local deletion affects this data directory. Removal for everyone requests removal on other clients; content already read or copied cannot reliably be recalled.

Search messages

Open the magnifier at the top, enter a term and select a result. Older history can only be loaded when available from the server archive.

Mentions

Mentions draw your attention to a group message. Choose mention notifications using the chat’s bell.

02 · Contacts & chats

Join or create a group

A group has its own address, for example treff@gruppen.dinox.im. Ask for the complete room address and any password. The part after @ may differ from your account address. Public rooms and private groups have different access rules.

Encrypted groups need suitable room settings and members’ device keys. Selecting a lock does not automatically make a public room private.

What to do

1. Open the group icon. Select a saved group or enter the room address.
2. Choose your account, room nickname and, if needed, the room password.
3. For a new room, choose “Add Group”. The server determines whether you may create a room.
4. After joining, read the topic, member list and any notice about visibility of your address.

What do the choices mean?

New group: address, alias and nickname

The room address identifies the room. Alias is your local display name for it. Nick is the name you use inside the room. An optional room picture can be selected in the form.

Private Room

Select deliberately when creating a room. DinoX requests the required private-room settings and checks the server result. Rejection or unconfirmed configuration does not mean a successfully private room.

Find rooms

The magnifier in Join Group opens the room browser. Browse offered server rooms there; the additional public search also searches outside your server after at least two characters. A result is something to inspect, not a room recommendation.

02 · Contacts & chats

Manage and leave groups

Management functions depend on your permissions. Members, moderators and owners have different rights. An invitation does not override the room’s access rules.

What do the choices mean?

Invitations and members

Choose “Invite Contact” in the group menu. The members icon shows participants and their menus. Check the account, room and person before acting.

Topic, picture and room configuration

Open room information in Details. With permission, change the topic, picture and properties. Membership, anonymity and passwords affect access and visibility.

Permissions and roles

With sufficient rights, change memberships or roles, remove people or ban them. Additional role labels (“Hats”) require server support.

Close and leave

Closing hides the conversation. Leaving ends participation. “Leave Permanently” also removes the bookmark and prevents automatic rejoining. The room and your local history are retained.

Destroy room

Affects the entire room and its members. It is not needed just to close your own chat.

Saved groups and bookmarks

Help you find and rejoin rooms. In narrow windows, expand the chat list or bookmark area if it is hidden.

02 · Contacts & chats

Share files, pictures and recordings

Open the right chat first. The paperclip is for attachments; the microphone and camera beside the input record messages. Start calls at the top of the chat instead.

What to do

1. Open the paperclip and select a file, or drag it from the file manager into the chat.
2. Check the recipient and preview, then confirm sending.
3. The microphone or video icon starts recording immediately. Send stops and sends it; Discard or Cancel discards it. Recording limits and details are covered in the voice and video message chapters.
4. Open or download received attachments through the message. Use the save action to keep your own copy.

What do the choices mean?

Size limits and errors

Upload limits are partly set by the server. Read any error and use the offered retry action; avoid repeatedly sending the same large file.

Recording devices

Messages can use different recording devices from calls. Both are under Preferences → Audio & Video.

Location

When available, share a location through attachments. General permission must be enabled. Check the location before sending.

02 · Contacts & chats

Show online, away or busy

Presence tells authorised contacts whether you want to be available. Away or Busy does not disconnect the account. Messages can still arrive. This status selection applies across your connected accounts.

What to do

1. Select the status speech bubble and choose Online, Away, Busy or Not Available.
2. Optionally choose Set Status Message and enter a short text such as “Back later”. Do not confuse this with a private chat message.
3. To actually disconnect one account, use its switch in Preferences → Accounts. Use Ctrl+Q to quit DinoX.

Invite someone to XMPP with a link

This creates a shareable invitation link through the selected account’s server. The server decides whether you may create links and how long they remain valid. It is separate from inviting someone to an active call or a group room.

What to do

1. Choose the account issuing the invitation.
2. Choose Create Link and wait for the server response.
3. Copy the offered web or XMPP link. If supported by the build, you can also use the QR code.
4. Share the link with the intended person. Read any expiry or permission message.

02 · Contacts & chats

Use emoji and stickers

Emoji are characters in text. Stickers are pictures from packs. Selecting a sticker can send it directly to the open chat, so check the recipient first.

What to do

1. Open the emoji selector and insert a character in your text, then send the message.
2. Open the sticker selector, choose a pack and then a sticker.
3. Use Manage Sticker Packs or Add Sticker Pack to add packs. Offered XMPP links and folders of pictures are supported.
4. For folder import, choose Local only to keep pictures on this device. Share and Copy Link uploads the stickers and publishes pack information.

What do the choices mean?

Import through an XMPP link

Read the account and publication notice: importing can make pack information publicly available through the selected account. Do not treat a link as a private file transfer.

Animations and disabling

Under Preferences → General → Stickers, control stickers and their animations.

02 · Contacts & chats

Find saved groups and server rooms

The search field in Join Group helps find your saved groups. Enter part of a name. If you know the full room address, you can enter it directly. This list is not a directory of every group on the internet.

The magnifying glass beside the search field opens Browse Rooms. With Search all public XMPP servers switched off, DinoX shows rooms advertised by your account’s group service. This queries the server; it is not purely a search on your computer. Private or hidden rooms may not appear.

What to do

1. Select the group icon and, with multiple accounts, choose the correct account.
2. For a saved group, search its name in the first search field and open the matching result.
3. To find more rooms, select the magnifying glass. Choose a room in the directory, then Join.
4. In the next dialog, check the room address, your name in the room and any required password. You only become a participant after completing the join.

02 · Contacts & chats

Search public groups across servers

Enable public search and enter at least two characters, such as a topic. DinoX queries the external search.jabber.network service, which receives your search term. It finds public rooms in that service’s index; despite the switch label, it is not a complete list of all XMPP servers.

A result is neither an invitation nor an endorsement. Read the description, language and room address. A password or membership may still be required. An empty result can also be caused by the search service.

What to do

1. Enable public search and enter a query.
2. Review the results, select a room and choose Join.
3. Complete the subsequent join dialog. If you already know the exact address, you can skip public search.

03 · Encryption & protection

The lock and the three message modes

The lock shows this chat’s setting. Select it to open the choices. Message encryption is separate from the secure connection to your server. The devices involved must also support the selected method.

The Encryption entry in a conversation’s context menu opens its keys and security settings directly. Conversation Details initially opens general information. Private groups have additional room and membership requirements.

What do the choices mean?

OMEMO

Encrypts for participants’ devices. Intended for normal use. Check new or changed device keys in Details.

OpenPGP

Requires configured keys and a compatible method at the contact. Account settings distinguish legacy OpenPGP from OpenPGP for XMPP.

Unencrypted

Without end-to-end encryption. A secure server connection does not prevent servers from processing message content. Select deliberately.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

03 · Encryption & protection

OMEMO: inspect devices and verify keys

A contact may use several devices, each with its own key. Accepted or Trusted means DinoX may use that key. Verified additionally means you deliberately checked its fingerprint. A green symbol alone does not replace that comparison.

Compare the complete fingerprint with the person, for example in person or through an already verified channel. A device number identifies an entry but does not prove who owns the device.

What to do

1. Open the correct contact’s encryption page and select the device.
2. Open Manage Key, then fingerprint verification.
3. Compare every character. Confirm as verified only if they match. If they differ, cancel and check with the person.

What do the choices mean?

Reject key

Rejects this device for encrypted communication. Other devices of the same contact have their own settings.

Reset session

Rebuilds the device’s encryption session on a subsequent message. Intended for specific delivery problems, not routine maintenance.

Long inactive / Remove device

Not seen for a long time does not prove a device is lost. Removal deletes its local key and session data. An active device may appear again. Confirm using the top button in the final step.

Reset all sessions

Affects the contact’s displayed sessions. It is different from deleting the account or all DinoX data.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

03 · Encryption & protection

Set up OpenPGP and use it with a contact

OpenPGP is a separate option alongside OMEMO. If methods or keys do not match on both sides, simply switching the chat lock will not help. First agree which OpenPGP variant the contact’s application uses.

What to do

1. Choose your account and create a key or import an existing one in key management.
2. Select the appropriate own key for this account. Keep the private key and its backup confidential.
3. Agree the mode with the contact. With OpenPGP for XMPP, publish your public key using the provided action.
4. Inspect the discovered or assigned key in the contact’s encryption details. Compare the complete fingerprint.
5. Then choose OpenPGP using the chat lock and follow the displayed status.

What do the choices mean?

Legacy OpenPGP · XEP-0027

Compatibility mode for older XMPP applications. Key association and retrieval differ from the newer method and may involve a keyserver.

OpenPGP for XMPP · XEP-0373/0374

Publishes public keys through the XMPP account and uses the corresponding message format. The server and contact must support the required features.

Import, export, delete and revoke

Import loads a key; export writes a file. A public export may be shared; an export including a private key is a confidential backup. Local deletion is not revocation. Revocation declares a key invalid and must be deliberate.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

03 · Encryption & protection

Login protection (MITM): understand status and choices

This additional protection helps prevent a sign-in being relayed over another connection. Technically, this is called channel binding. It protects this account’s sign-in; OMEMO and OpenPGP protect your messages.

Server Support shows this account’s result: a green check for available support, a red cross for missing support. Not yet checked is not a confirmed no. Current Connection states whether protection is actually active for the present sign-in.

What to do

1. Read server support. If unknown or outdated, choose Check Now. Only this account reconnects.
2. Choose the desired mode. DinoX checks the choice and automatically reconnects the account after a change.
3. Read the result and Current Connection. An unavailable protection feature cannot be treated as successfully enabled.

What do the choices mean?

Use when available

Uses additional protection for supported sign-ins. This is the default for newly configured accounts. The choice appears after support is confirmed.

Require for sign-in

This account may sign in only with additional protection. If support later disappears, sign-in is refused. A recovery action deliberately relaxes this requirement.

PLAIN password authentication

A separate advanced-account exception for servers without SCRAM. The password travels inside the TLS connection. Off by default; once SCRAM is confirmed, PLAIN stays blocked. Do not enable it for unrelated sign-in failures.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

03 · Encryption & protection

DNSSEC, DANE and the server certificate

DinoX must find the correct server and check its identity. DNSSEC validates protected information about server addresses. DANE can additionally specify which server certificate is accepted. These settings are per account and do not change message encryption.

What to do

1. Choose the mode and, if needed, a resolver URL.
2. Choose Apply. This saves both settings only for this account and reconnects it when enabled.
3. Read the result. Another account’s green status does not prove this account is working.

What do the choices mean?

Off

Uses normal TLS certificate checks. This does not automatically make the connection unencrypted.

Check automatically

Uses available validated DNS and DANE information. Missing signatures differ from failed validation: errors or failed lookups are not silently ignored.

Require DNSSEC and DANE

Connects only when the required evidence is present and valid. Without it, this account remains disconnected.

HTTPS DNS resolver URL

An additional service returning DNS answers over HTTPS. Enter a suitable resolver URL. Without one, direct connections use system DNS. Tor or SOCKS5 requires an HTTPS resolver through the proxy.

Server certificate

Shows details such as issuer, validity and fingerprint. This is the server certificate, not the contact’s OMEMO key. Check certificate errors with the provider.

Updated 24 October 2026 · DinoX 2.3.2 · Screenshots use demo accounts.

03 · Encryption & protection

Tor, bridges and your own SOCKS5 proxy

Tor routes connections through the Tor network. A SOCKS5 proxy is an intermediary you specify. Neither replaces an XMPP account or message encryption. Integrated Tor is an application-wide setting and can override an account’s own proxy.

Lyrebird is the included helper for certain Tor bridges. It does not require a second chat account. Bridges are particularly useful when ordinary Tor connections are blocked.

What to do

1. For integrated Tor, open the Tor tab and enable it. Wait for connection progress.
2. If Tor is blocked, enable Use Bridges. Enter a valid list or request obfs4 or WebTunnel bridges.
3. Use Firewall Mode only with bridges on port 80 or 443. Read restart and status messages after changes.
4. For an account’s own proxy, enter its SOCKS5 address, port and required credentials in that account’s settings, then check its status.

What do the choices mean?

DNSSEC/DANE through a proxy

Also configure an HTTPS DNS resolver as described under Connection Security. Use a numeric proxy IP address where required by the interface.

MQTT and local devices

MQTT has its own broker settings. Local brokers may use a direct local route, so a green Tor status is not proof of routing for every external service.

03 · Encryption & protection

Back up and recover an OpenPGP key on the server

This stores an encrypted backup of the selected account’s private OpenPGP key on its server. It differs from publishing the public key and from a full DinoX data backup.

Importing or fetching a key from the server does not automatically activate it. After retrieval, check the key selected for this account and the mode it is published for.

What to do

1. Open the correct account and your own key. Choose Backup Secret Key to Server.
2. Copy the displayed backup code and keep it safe. Then confirm upload and wait for success. Exactly this code is required for recovery.
3. On another device using the same account, choose Fetch Key from Server (Sync) and enter the backup code.
4. Check fingerprint and account association. Deliberately confirm any selection or publication.

What do the choices mean?

Delete Server Backup

Removes only this encrypted server backup. Local keys and public-key publications remain.

Cleanup pending

Read the displayed status. If removal of the server backup is not yet confirmed, do not treat it as completed.

04 · Audio & video

Prepare microphone, speakers and camera

DinoX distinguishes call devices from recorded-message devices. A working voice message does not automatically prove the correct call microphone is selected. System Default uses the operating system’s selected device.

What to do

1. Choose the microphone, speakers and camera under Audio/Video Calls.
2. Further down, select devices for voice/video messages.
3. Run the offered tests: listen to the speaker tone, check a short microphone recording and view the camera preview. These tests do not call anyone.
4. Refresh the device list after connecting a device. Check the camera cover, system permission and whether another application is using the camera.

What do the choices mean?

Call Network Mode: Automatic

Normal setting. Changes apply to new calls.

Low bandwidth (2G, audio calls only)

For very slow connections; limited to audio calls. It is not a low-quality video mode.

04 · Audio & video

Call someone and answer a call

The phone at the top starts a call. The microphone and camera beside the message field are for recorded messages. The contact needs a reachable client supporting compatible calls.

What to do

1. Open the correct contact chat. Select the phone and choose the offered audio or video call.
2. Accept or reject an incoming call. The conversation starts after acceptance.
3. Mute or unmute the microphone in the call window. The camera has its own on/off control.
4. Use the microphone and camera device selectors if you need another device. Video effects have a separate button.
5. End the call with the red hang-up button. Switching chats is not a substitute for hanging up.

What do the choices mean?

No picture

First check the local camera preview, camera cover and selected camera. A black camera image can stay black even when transmission works.

No sound / echo

Check mute, volume and selected devices. Headphones prevent speaker output feeding back into the microphone.

Connection details and encryption

Call-window indicators refer to this call. A green message-encryption indicator alone is not proof for every media path.

Dialpad (DTMF)

For a destination with a telephone menu, the dialpad can send digits, such as choosing a hotline option. This requires a suitable telephony service and does not automatically give DinoX access to the telephone network.

Group calls and inviting another person

A group call connects several people. Invite Contact in a text group menu initially invites someone to the room; Add Participant in a call window concerns the active call. These actions are different.

DinoX uses OMEMO v1 for the encrypted MUJI calls described here. A client restricted exclusively to PQ/OMEMO 2 is not automatically compatible. Installing Monocles alone does not determine the mode used in a particular conversation.

What to do

1. For an existing private room, open the group and choose the offered call action. Check permissions and encryption status.
2. To extend a one-to-one call, choose Add Participant in the active call window and select a compatible contact.
3. Wait for invited people to accept. Sending an invitation does not mean someone has joined.
4. Check the participant list for people actually connected. Microphone, camera and hang-up controls remain in the call window.

What do the choices mean?

If the action is missing or disabled

The current room, permissions or client capabilities do not meet requirements. Describing this flow is not proof that every third-party client combination was tested.

Open or rejoin a call

The call menu may offer to open or join an ongoing group call. After leaving, Rejoin previous group call may appear. If it is no longer available, start a new call; an old history entry alone does not prove a call is active.

Framing and appearance

Choose automatic framing, a colour filter or an effect preset. Adjust strength where a slider is provided.

Background

Choose blur, colour, an offered scene or your own image. On a loading error, choose another image or disable the background.

Face and animations

Choose offered glasses, hats, beards, face accessories or animations. Availability and appearance depend on the image and runtime.

Play voice and video messages

A recording is a stored message. Playing it does not call anyone. Depending on download status, the file may need to be downloaded first.

What to do

1. Press Play on a voice message. The waveform or timeline shows progress and lets you seek.
2. Pause to stop playback. Use offered volume or playback-speed controls where available.
3. Open videos directly in the chat and use playback controls. A download in progress does not mean the full video is available.

Record a voice message

A voice message is a recording for later listening. It does not call anyone. First open the intended contact or group. For a live conversation, use the phone at the top instead.

Do not leave recording unattended: reaching the five-minute recording limit automatically ends the recording for sending.

What to do

1. Open the correct chat. Select the microphone at the bottom: recording starts immediately. Allow system permission if needed.
2. Speak into the microphone; the recording panel shows elapsed time and input level.
3. Send ends and sends the recording. There is no separate playback-preview step here. Discard throws it away; Escape also cancels.
4. Later, listen to the message using its play button in the chat. A new recording is another message.

Record a video message

A video message is a file with picture and sound for later playback. A video call is a live conversation. Pay attention to whether you use the video icon beside the message field or the phone at the top.

Reaching the two-minute recording limit also triggers sending. Choose Cancel in time if you do not want to send anything.

What to do

1. Open the correct chat and select the video icon at the bottom. Recording starts immediately, so check the camera cover and devices first.
2. Watch the live camera preview and timer. Picture and sound are being recorded.
3. Send ends and sends the recording. Cancel discards it. There is no additional pre-send playback confirmation.
4. Open and play the sent video in the chat. Recipients can watch it later.

05 · Feeds

What is a feed, and which route do I need?

A feed is a list of new posts, such as news or software releases. You can read posts, send a post to a chat or publish your own posts. These are separate tasks.

First choose the account at the top. Subscriptions and chat destinations belong to this account. A feed subscription is neither group membership nor a contact request.

What do the choices mean?

Web feeds

Read a website’s RSS or Atom address. Share individual articles or automatically post new ones to selected chats.

Read XMPP feeds

Read and subscribe to an XMPP account’s personal feed. New posts do not automatically appear in chat.

My XMPP feed

Publish your own posts on the server. Authorised readers can retrieve them while DinoX is closed.

Subscriptions

Inspect, pause, change or stop the selected account’s subscriptions and automatic posting.

Read a web feed and share an article

You need the feed URL, not just a website’s home page. An example is https://git.dinox.im/dinoxim/monocles-chat/releases.rss. The content comes from that publisher.

What to do

1. Enter the feed URL and choose Load articles.
2. Find an article and open Preview and share. Show more articles if needed.
3. Check the destination chat and message text in the preview. The chat must belong to the selected account.
4. Check the displayed chat encryption. Only Send transmits the article as a readable message with a link to its source.

Automatically post new web articles to a chat

This automation runs only while DinoX is running and the selected account is connected. It is not a server-hosted bot. Existing articles are skipped when enabling it; new articles are then checked, with up to five queued per check.

What to do

1. Load the feed first. Choose an interval from 5 minutes to 24 hours; the default is 30 minutes.
2. Open Automatically post new articles, check the destination and encryption, then confirm with Enable.
3. Under Subscriptions, inspect the last check time and status. Use Save interval there after changing the interval.
4. Use Pause to stop temporarily or Stop automatic posting to remove the route. Already sent messages remain.

What do the choices mean?

Encryption changed

If chat encryption changes, the route pauses. Check the destination and new setting, then deliberately resume with the current chat encryption.

Subscribe to another person’s XMPP feed

Enter the publisher’s XMPP address here. Leave the advanced node setting unchanged for a personal feed. A PubSub service with another node requires the operator’s details.

A subscription asks the server for notices of new posts. An open subscribed feed refreshes on a server notification; otherwise read it again. Up to 100 recent posts are shown. Images and external content are not loaded automatically.

What to do

1. Enter the address and choose Read XMPP feed.
2. Choose Subscribe to this XMPP feed for future notices. The owner may need to approve access first.
3. Check status under Subscriptions. Read feed opens it; Unsubscribe stops notifications.
4. If needed, separately share an article to a chat through Preview and share. Subscribing alone sends no chat messages.

05 · Feeds

Publish your own posts: who can read them?

Your first published post creates a personal feed on the XMPP server if supported. Give readers the selected account’s XMPP address. They need a feed-capable client and access permission.

XMPP feed posts are not end-to-end encrypted. Without Public feed checked, contacts you have allowed to see your online status can read it. This is not automatically every saved address. Checking it makes the feed publicly readable.

Visibility applies to the entire feed. This writing dialog cannot change an existing feed’s visibility. DinoX currently does not show a subscriber list.

What to do

1. Check the account and open the writing dialog. Choose visibility for a new feed.
2. Enter title and text. Only Publish places the post on the server.
3. Retrieve the result with Read my feed. Use the remove action on your own posts to delete one.
4. For contact access: contact chat → Conversation Details → About → Contact permissions. Accept an appropriate presence request or choose Also share my online status when adding the contact.

What do the choices mean?

What happens while DinoX is closed?

The server keeps published posts available to authorised readers. New posts require publication; they do not appear by themselves. Web feeds are not automatically copied into your XMPP feed.

Advanced sign-in: server and proxy

For normal sign-in you usually do not need to enter anything here. DinoX finds the server from your XMPP address. A proxy is an additional intermediary for the connection; it is not your XMPP provider.

What do the choices mean?

Server and port

Only enter special values supplied to you. These change the connection destination, not your XMPP address. Otherwise leave them empty.

SOCKS5 proxy

Enable only if you have access to such a proxy. Enter its address, port and, if needed, its username and password. An incorrect proxy prevents sign-in.

06 · Accounts & settings

Accounts, profile and availability

DinoX can manage several XMPP accounts. Contacts, keys and connection rules belong to individual accounts. Check the address before making changes. Use the plus in the account overview to add another account.

Temporarily disabling an account differs from removing it. Local removal does not automatically delete the account at its provider. Read the confirmation carefully.

What do the choices mean?

XMPP address and local alias

The address identifies the account. A local alias helps you distinguish your own accounts.

Password

Changes the provider account password: enter the current password and the new password twice, then confirm. Other devices must subsequently use the new account password. The local DinoX database password remains unchanged.

Connection status

Shows whether this account is connected or why sign-in failed. Other accounts can have a different state.

Public profile

Edit your picture, name, nickname and optional details. Only enter a birthday, address, phone or job information if you want to share it. Check “Public Access” and “Share with Contacts”, then save changes.

Timezone

Timezone sharing tells contacts your local time. It does not send your precise location.

Login protection and connection security

These rules apply only to the selected account. Their chapters explain the indicators and choices.

Appearance, language and notifications

These settings affect DinoX on this computer. Individual chats can have their own settings. Scroll down on long pages; the tabs at the bottom switch sections.

What do the choices mean?

Send Typing Notifications

Others can see that you are typing. Unsent text is not transmitted.

Send Read Receipts

DinoX may tell others that you read a message.

Sync Read State Across Devices

Synchronises your read position through your account with your other devices. Contacts cannot see this internal synchronisation.

Allow Location Sharing

Allows the location feature but does not send your location automatically. It requires a build with location support and a location source.

Notifications and sounds

Controls visual and audible new-message alerts. Use the bell or mute for individual chats as well.

Minimize to System Tray on Close

Closing the window keeps DinoX running when your desktop supports a tray. Ctrl+Q quits DinoX. Automatic feed checks require the DinoX process to remain running.

Colour scheme and accent colour

Choose light, dark or the system appearance. The accent colour changes highlights, not encryption.

Chat font and text size

Adjust message and input text for readability. Larger text takes more space.

Language

Changes the interface but does not translate messages. Restart if requested.

Smileys and stickers

Smileys can be converted into emoji. Stickers can be disabled; turning off animations shows still images.

06 · Accounts & settings

Set up notifications and sounds

Notifications alert you to new messages. The general setting applies to DinoX as a whole. You can additionally set each contact and group separately. Your online status is a separate setting.

Check three places in this order: the general DinoX setting, the affected chat’s bell and your operating system’s notification permissions. An enabled chat bell cannot override globally disabled notifications.

What to do

1. Under General, enable Notifications if DinoX should show alerts for new messages.
2. Turn Message Notification Sounds on or off separately. Turning sound off is not the same as muting a chat.
3. Open the desired chat and select the bell at the top. In groups, choose all messages, mentions only or no alerts. Reset to default restores the default behaviour.
4. Allow DinoX notifications in Windows or your Linux system settings. A system-wide do-not-disturb mode can still suppress alerts.

What do the choices mean?

Mute

Suppresses alerts for this chat. Messages still arrive. The contact is not blocked.

Mentions only

In groups, limit alerts to mentions of you. Useful in busy public rooms.

Minimize to System Tray on Close

When enabled and supported by your desktop, closing the window leaves DinoX running in the background. Quit or Ctrl+Q exits completely. DinoX notifications and local feed checks then stop.

07 · Data & backups

Back up data and move to another computer

The backup covers the local DinoX data directory and its accounts. It is not a backup of the entire XMPP server. Keep the file separately from the computer it protects.

An encrypted backup archive password differs from the account password. Later you also need the local database password belonging to the backed-up data. Keep both safe.

What to do

1. Open Backup, set a password for the encrypted archive and select the destination.
2. Wait for successful completion. Keep the file and required passwords safe.
3. To move, choose Restore on the destination device. It is also available during initial setup.
4. Select the backup, enter the archive password if needed and read the replacement warning. Back up existing destination data before replacing it.
5. After completion, restart as instructed, unlock, and check accounts, history and keys.

07 · Data & backups

History, server archive and retention

Your computer, the XMPP server and contacts’ devices may hold different copies of a conversation. Local deletion does not automatically remove every copy. Missing history cannot simply be reloaded without a server archive.

What do the choices mean?

Load messages now

Requests available older messages from the server archive. Group details offer a custom number of days to load. Load now fetches them; the setting also applies on the next join. Cleared or expired messages remain excluded. The server may have less history.

Delete conversation history

The confirmation explains which local messages or files will be removed. Save attachments you need first.

Retention rules

In Conversation Details, choose Auto-delete messages: never, after 15 or 30 minutes, 1 or 24 hours, 7 or 30 days. The choice is saved. Local deletion does not guarantee other devices delete their copies.

07 · Data & backups

Clean up storage, change the password and reset data

These actions affect the local DinoX data directory. Make a backup before resetting. Selecting an account elsewhere does not restrict these general actions to that account.

What do the choices mean?

Data location

Opens or shows the local data location. Flatpak uses a separate location from a regular installation. Do not delete database files at random while running.

Change database password

Changes the password unlocking local data. Does not change provider account passwords.

Clear cache

Removes cached data as described in the confirmation. Pictures or other content may need to be downloaded again.

Reset database

Removes data including messages, files and OMEMO keys while retaining accounts. This is a major operation, not a routine speed optimisation.

Factory reset

Removes local accounts and data. Read the exact confirmation first. It does not automatically delete registration at the provider.

Panic Wipe

Deletes local DinoX data and exits. Available in the main menu or through Ctrl+Shift+Alt+P; it is not normal quitting. Three failed normal unlock attempts also trigger it. The special post-restore unlock flow is exempt.

08 · Bots & automation

Botmother, AI assistant and Telegram

A bot processes messages or performs configured tasks. You do not need these features for normal chatting. Local Botmother requires DinoX to be running; a separately hosted CloudBot is a different service.

An AI or Telegram integration passes content to the configured service. Deliberately choose destinations, permissions and provider before enabling it. An API token is an access key and does not belong in public chats or pictures.

What to do

1. Enable Botmother under General. Keep the local API mode for normal local use.
2. Open Botmother for the intended account. Check account activation and create a bot or select an existing one.
3. Set the name, permissions and target restrictions. Permit only required actions and save.
4. Configure and enable additional sections individually. Use status indicators and offered test actions.

What do the choices mean?

AI Assistant

Enter the provider, model, credentials and any custom server address. The AI test question checks a response without sending it to an XMPP chat. Costs and data processing depend on the chosen service.

Telegram bridge

Enter the Telegram bot token, chat ID and offered mode, save and enable. A Telegram chat ID is not an XMPP address. Check destination and direction before real use.

Webhooks and local API

For integrating your own software. A webhook sends events to a configured address. Configure network mode and a TLS certificate only when deliberately granting other devices access. Use the API documentation for concrete programming calls.

CloudBot

An existing hosted bot can be loaded using its management token. Check ownership and status. Local API tokens, CloudBot management tokens and event tokens are different credentials; rotation can invalidate previous access.

08 · Bots & automation

MQTT: read device values and send commands

MQTT is often used for sensors and home automation. The broker is the intermediary server. A topic is a named message destination, such as home/temperature. You need the operator’s details; an XMPP account alone is not access to an unrelated MQTT broker.

Standalone means a broker connection independent of your XMPP accounts. An account’s MQTT bot belongs to that account and can use a suitable XMPP-server MQTT service or a custom broker.

What to do

1. Open the appropriate section. Enter broker address, port, TLS and required credentials as supplied by its operator.
2. Enable and choose Save & Apply. Read connection status; Reconnect does not replace saving changed values.
3. Open the MQTT Bot Manager and first subscribe to a known topic. Check the received value from an active sensor.
4. Use Show Bot in Chat to open the local display. Configure publication and automation rules only after checking destinations.

What do the choices mean?

TLS and DNSSEC/DANE

TLS protects the connection to the broker. Without TLS, credentials and values on a remote connection may travel in plaintext. Additional DNSSEC/DANE settings belong to that broker connection.

Home Assistant Discovery

Announces DinoX as a device to the configured Home Assistant MQTT service. The discovery prefix must match its configuration. This does not replace broker credentials.

MQTT subscriptions, presets, alerts and bridges

The manager states when changes are saved: topic subscriptions and publishing/free text use Save & Apply; alert and bridge rules save immediately. Pause Messages hides the display while incoming values continue to be recorded.

What do the choices mean?

Subscribe to topic

Enter the topic, optional alias and required delivery level (QoS), add it and save. Wildcards can match many topics; subscribe only to the needed scope.

Publish preset

Enter a recognisable name, destination topic and content (payload). Triggering it may control real devices; check destination and content first.

Free-text publish

Configure a publish topic and optional response topic. Deliberately send entered text through this connection, for example to a matching Node-RED flow.

Alert rule

Choose the topic pattern, optional field within a JSON message, comparison and threshold or keyword. Priority determines the alert’s classification.

Bridge rule

Defines which MQTT messages are forwarded to which XMPP address. Check destination, format and sending account. This may expose device values to other people.

Server administration: requires permissions

This entry appears only when DinoX detects suitable administration commands for an account. Ordinary users do not need to enable anything. The server determines available commands and form fields.

What to do

1. Choose the administrative account and refresh commands if needed.
2. Open the relevant section: user accounts, rosters, groups, server or other commands.
3. Complete required fields and check the target server, account or room. Use Next or Previous in multi-step forms.
4. Check deletion actions especially carefully before final confirmation. The server response confirms success; submitting a form alone does not.

09 · Help & terminology

When something does not work

Note the DinoX version, operating system, package and exact steps to the problem. A picture of the affected setting helps; exclude passwords, private keys and tokens. Describe what you expected and what you actually saw.

What do the choices mean?

Unlock failed

Check the local database password, not the account password. “Invalid key or corrupted” alone does not prove corruption. Do not immediately reset.

One account stays offline

Check account settings and the specific error: internet, credentials, server, proxy or required protection may be involved. Other connected accounts do not prove these credentials are correct.

Encrypted message not received

Check the contact or room, selected method and device keys. Groups need known membership and the actual participants’ keys. Do not delete all keys indiscriminately.

Feed empty or access denied

Check feed address, selected account and read permission. A personal XMPP feed may not exist until its first publication. Subscribing does not create someone else’s feed.

Missing DEB dependency

First compare package and distribution. The Ubuntu package is not the appropriate choice on Debian 13. Use APT on the supported system to resolve dependencies.

Camera or microphone missing

Check system permission, cable, camera cover, device selection and device tests. For Flatpak, also check package permissions.

Terms without assumed knowledge

What do the choices mean?

XMPP address / JID

bob@dinox.im is an example chat address: bob is the account name, dinox.im the provider. JID is the technical term. Looking like email does not automatically make it an email inbox.

Server / provider

The service your account connects to and which routes messages.

MUC / room

A group chat with its own address and access rules.

MUJI

The method for organising group calls through XMPP rooms.

Fingerprint

A character sequence for comparing a key. Compare all of it, not only the beginning and end.

TLS

Encrypts a connection to a server. End-to-end encryption additionally protects message content between devices.

Subscription

Depending on context, permission to see online status, a feed subscription or an MQTT topic subscription. These three are independent.

Local

On this computer or in this DinoX data directory. Not automatically on the server or other devices.
