About Tutanota
Tutanota is the world’s first end-to-end encrypted mail service that encrypts the entire mailbox. With its unique open source technology Tutanota fights for privacy and freedom of speech online. Started as a secure email service in 2011, Tutanota now offers an encrypted address book, an encrypted calendar and the encrypted contact form Secure Connect.
In addition, Tutanota’s affordable business version enables companies and organisations of all sizes to easily secure their email communication.
Mission
Privacy is the foundation of everything we do. To fight for our right to privacy – to protect journalists, whistleblowers and human rights activists as well as citizens around the world – this has been our mission since we have started building the encrypted email service Tutanota.
Join us in our mission to spread privacy via our community page.
We embrace full transparency and disclose mistakes openly and transparently. Security and transparency are closely interlinked and one cannot be achieved without the other.
We take our social responsibility seriously by running Tutanota completely on renewable energy and by offering the secure email service at a discount to NPOs and schools.
Team Spirit
√ Courage: We discuss conflicts, admit mistakes and propose ideas even if they may sound silly at first. We ask for help and offer help to each other if needed.
√ Responsibility: We decide on strategy, planning and design in teams. We incorporate pair programming.
√ Appreciation: We appreciate each other’s ideas and accomplishments.
√ Respect: We respect each other and their opinions.

ProtonMail
End-to-End Encryption
Messages are encrypted and stored on ProtonMail servers at all times. They are also transmitted in encrypted format between our servers and user devices. Messages between ProtonMail users are also transmitted in encrypted form within our secure server network. Because data is encrypted at all steps, the risk of message interception is largely eliminated.
Zero Access to User Data
ProtonMail’s zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that we do not have access to. This means we don’t have the technical ability to decrypt your messages, and as a result, we are unable to hand your data over to third parties. With ProtonMail, privacy isn’t just a promise, it is mathematically ensured. For this reason, we are also unable to do data recovery. If you forget your password, we cannot recover your data.
Open Source Cryptography
We use only secure implementations of AES, RSA, along with OpenPGP. Furthermore, all of the cryptographic libraries we use are open source. By using open source libraries, we can guarantee that the encryption algorithms we are using do not have clandestinely built in back doors. ProtonMail’s open source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection.
