At Proton, our commitment to transparency and privacy has always guided how we develop our services. We believe you must be able to investigate and verify apps for yourself if you want to make an informed decision about what happens to your data. Today, we’re proud to announce that all Proton Drive apps are now fully open source, including the Proton Drive desktop apps.
This milestone underscores our mission to build privacy-first solutions that you can trust. By making all our apps open source, we empower our community and the broader security sphere to inspect, verify, and trust the protections we’ve built into Proton Drive to safeguard your data.
Making our apps open source is one way we demonstrate our belief that privacy shouldn’t require blind trust. By providing full access to our source code, we enable anyone to verify that our apps function as promised, delivering the security and privacy we claim.
Sharing our apps’ source code publicly also allows us to leverage the security community to quickly find, identify, and resolve potential vulnerabilities rather than rely on security through obscurity. Developers, security researchers, privacy advocates, and anyone who is interested can inspect any Proton Drive app. This transparency strengthens the security of our services and gives our users full confidence in how their data is protected.
