About

Tuta (formerly Tutanota) is a privacy-first email, calendar, and contacts service that uses end-to-end, quantum-resistant encryption to keep user data private. It is fully open source, ad-free, and powered by renewable energy, with apps available across Android, iOS, Windows, macOS, and Linux. The service is aimed at individuals, businesses, journalists, and activists who want to communicate without surveillance or data exploitation.

Problem

Mainstream email providers scan and monetize user data through targeted advertising and surveillance, eroding digital privacy.

For

Privacy-conscious individuals, businesses, journalists, and activists

How it works

Tuta automatically encrypts all emails, calendars, and contacts end-to-end with quantum-resistant cryptography, storing data on servers in Germany under strict GDPR protections with a zero-knowledge architecture.
