  • All sensitive information including messages are encrypted at rest with Sailfish Secrets

Sailtrix features an encrypted message cache to load only the newest messages when you open a room, improving its performace significantly. However, it can corrupt at times, and may cause strange behavior, such as the wrong avatars being displayed. It is easy to clear this cache in the settings.

There are currently many features that are not implemented. Please see the GitLab issue tracker for an incomplete list. Feel free to add to it if you want a feature to be implemented or a bug to be fixed.

Sailtrix has been tested to be working on Sailfish 3.4 and newer.

A note on notifications

Sailtrix >= 1.3 supports notifications. They may eat battery as it causes the phone to wake up every 30 seconds - you can change this interval in the settings. You can also disable them there. Every time you restart your device, you will need to launch Sailtrix to start the notifications. Then, you can close the app.

Emoji verification instructions

Currently, emoji verification is highly experimental. It can only be started from another device, such as Element, and you must be on the Rooms list to receive the emoji verification flow.


Pipeline status

Development status and source code are available on GitLab ( - feel free to fork and submit merge requests.


I'm not always available for support and it may take a few hours or days for me to respond. Discussion will take place in the Sailtrix matrix room:


Please note that to prevent strange occurrences, one should execute "killall harbour-sailtrix" to stop the daemons before updating.

Issue open here:
In SFOS 4.0 libcrypto was updated to 1.1 and the packages were built with 4.1 sdk

Hi, with the 3.4 release of sailfishos i have got an error with libcrypt. Do you support this release ?

HengYeDev's picture

Best way is to try it :) It should work as libcrypt is not used, only libcrypto, and only one function as of now (RAND_bytes) is used now.
