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, period. Our technology and business are based upon this fundamentally stronger definition of privacy.
Proton is an open-source company. All the source code used in our applications is public and freely available for inspection. As a company created by former CERN scientists, we believe strongly that trust is earned through transparency.
Anybody can check that our services work as described by reviewing our open-source code. Our privacy claims are also verified through regular audits by independent security experts.
