From public sourcesTuta Mail is an open-source, end-to-end encrypted email app that protects your emails, contacts and calendar on all your devices.
Overview
Most email services leave messages readable by the provider, so private conversations depend on trust. Tuta Mail is a secure email service with built-in end-to-end encryption that keeps emails, contacts and calendar entries protected on every device you use.
You can use Tuta through the web client, the iOS and Android apps, F-Droid, or the desktop client, and communicate securely with anyone who has an email address. The project is licensed under GPL-3.0 and its source code is published on GitHub, so the implementation can be inspected and built from source using the project's documentation.
Tuta suits people and teams who want private email without managing their own mail server, including users who need a privacy-focused alternative for personal or professional correspondence.
