Fundamentally different

Fundamentally different

Most tech companies, whether it’s Google or Apple, define privacy as “nobody can exploit your data except for us.” - We disagree. We believe nobody should be able to exploit your data.

Our technology and business are based upon this fundamentally stronger definition of privacy, backed also by Swiss privacy laws.

Privacy for a better world

Proton apps have advanced anti-censorship technologies built-in, so you can access your email, files, calendar, passwords and VPN even from countries with limited online freedom.

Free forever

We believe that privacy is a human right, and that's why Proton services are always available for free and our encryption technology is free software.
