Swiss Based
ProtonMail is incorporated in Switzerland and our servers are located in Switzerland. We are outside of US and EU jurisdiction and all user data is protected by strict Swiss privacy laws.

Zero Access
Because of our end-to-end encryption, your data is already encrypted by the time it reaches our servers. We have no access to your messages, and since we cannot decrypt them, we cannot share them with third parties.

Backwards Compatible

Forever Free
We believe privacy is a fundamental human right and should be available for everyone. That's why we offer multi-tiered pricing including a free version that anyone can use. Let's bring privacy back to the people!

Fully Anonymous
We do not log IP addresses or require any personal information to sign up. We accept bitcoin and cash payments for paid accounts to ensure even paid account users have complete privacy.
