    About Tuta Mail

    Tuta (formerly Tutanota) is a pioneer in secure communication, offering the world's first end-to-end encrypted email service with post-quantum security. Based in Hanover, Germany, the service is designed around 'privacy by default,' ensuring that even the service providers cannot access user data, including subject lines and attachments. The platform provides a comprehensive suite including Mail, Calendar, and Contacts, with a focus on ease of use and sovereignty. By operating its own infrastructure in Germany and refusing to use third-party cloud services like AWS or Google Cloud, Tuta ensures strict adherence to GDPR and German privacy laws, protecting users from invasive foreign surveillance.
