Tuta Review

Overview

Tuta (formerly Tutanota) is one of the most established secure email providers, founded in 2011 in Hanover, Germany. The service is fiercely independent, fully open-source, and focuses on providing the highest level of E2EE for email, calendars, and contacts. Tuta uses a proprietary implementation of AES and RSA for E2EE, which also encrypts metadata like subject lines. The company is pioneering post-quantum cryptography (TutaCrypt) to protect data against future quantum computer attacks. All user data is stored on Tuta's own servers in Germany, powered by 100% renewable energy. The Android app is available on F-Droid, free from any Google dependencies.
