Overview
Tutanota (now rebranded as Tuta) is a secure email service based in Germany that provides end-to-end encryption for emails, including subject lines, bodies, and attachments. The service uses zero-knowledge encryption, meaning even Tutanota cannot access the encrypted data stored on its servers. Tutanota offers an encrypted calendar and address book, two-factor authentication through TOTP or U2F methods, and allows anonymous registration without requiring personal information such as phone numbers. The service's clients are open source, allowing transparency and community verification of security measures. Tutanota operates under Germany's stringent data protection laws and GDPR compliance, ensuring user data is collected and used only with explicit consent. The service strips IP addresses from emails by default, preventing the tracing of messages back to users. Tutanota offers both free and paid plans, with the free plan providing 1 GB of storage, one user, and one calendar, while premium plans offer additional features and storage.
