Your privacy is our first and only priority
Unlike Big Tech, Proton believes in privacy by default. We don’t (and can’t) access or monetize your data, and we don’t answer to investors — just you.
End-to-end encrypted
We encrypt your files, their names, and more right on your device before they’re uploaded to the cloud, so only you hold the keys to unlock them.
Swiss Privacy
Proton is based in Switzerland, so your files benefit from some of the world’s strictest privacy laws, keeping out of US and UK jurisdiction.
Open source
Our encrypted cloud storage is regularly audited by independent experts, and our code is publicly available for anyone to review and verify.

What is cloud storage and how does it work?
Unlike traditional forms of data storage (such as hard drives), cloud storage uses servers in off-site locations to store data, letting you access your files any time you want as long as you have a device that connects to the internet.
