Proton Drive review

Proton Drive is cloud storage first, but its privacy design makes it a fair home for sensitive photos. The App Store listing says content is end-to-end encrypted so even Proton cannot view it, and that metadata such as filenames, sizes and modification dates is protected as well. The code is open source. Photos and videos back up automatically in original quality, and the app can be locked with a PIN or biometrics. Sharing uses links that can carry a password and an expiry date. Every account gets 5 GB free, and Drive Plus starts at $4.99 a month on the US App Store. What it does not have is a separate hidden album or any vault tricks: the lock covers the whole app, and there is no decoy or disguise. We compared documented features and published prices; we did not test each app.
