Tuta (formerly Tutanota) mail service

Tuta, originally known as Tutanota, is a pioneer in the secure communication sector, offering end-to-end encrypted email, calendar, and contacts services. The service was developed by Tutao GmbH, a company founded in 2011 and headquartered in Hanover, Germany. Unlike many tech companies, Tuta is built on an open-source model, allowing transparency and security audits of its client-side code.

The product is strictly hosted and developed in Germany, benefiting from the country's stringent data protection laws and the GDPR. It is unique in the tech landscape for its commitment to privacy, operating without reliance on Google-integrated services and using its own infrastructure to ensure that user data stays private and protected from mass surveillance.

Ownership of the brand remains independent, with the original founders still at the helm. This independence is a core part of their brand identity, ensuring they are not beholden to external corporate interests or advertising models that compromise user privacy. The shift from Tutanota to Tuta in late 2023 was part of a rebranding effort to provide a shorter, more memorable domain name while maintaining the same security standards.
