We know that the best way to build trust is not to ask for it, it's to act in a trustworthy way. That's why we try to make our systems and processes as transparent as possible so that users can verify for themselves whether their information is safe. Anyone can check public documents to see who runs our company and how we created Proton. We publish a transparency report and a clear privacy policy. We routinely subject our code to third-party security audits and publish the results. And of course our software is free and open source.
