All Tutanota apps are Libre software to provide an
open source email alternative to Gmail, Yahoo, GMX and others. To us this includes to publish our Android app on F-Droid.
Unlike other secure email providers, Tutanota does not use closed third party code - whether from Google or others -
because we must be in full control of the open source code to offer maximum security and privacy.
Our focus on open source and encryption combined with our deep respect for your right to privacy,
makes Tutanota the best secure email service.
