Notice
DeltaTouch is an e-mail client with a chat-style interface. It can also create unlimited free e-mail addresses on any Chatmail-compliant server (https://chatmail.at). It sets up end-to-end encryption automatically whena contact is added, using the SecureJoin protocol (https://securejoin.readthedocs.io). It can also be used for unencrypted e-mails.
Deltatouch is convergent and should work on any mobile or desktop Linux operating system. It shares a backend with Deltachat. It is available in the Ubuntu Touch package database. It is not yet packaged for Debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1073037#14) but there is a Debian and Droidian installer (https://codeberg.org/lk108/deltatouch/wiki/Installation-on-Mobian-and-Droidian-%28manual%2C-experimental%29).
