Proton

Proton Drive provides secure, end-to-end encrypted cloud storage, ensuring that only you and authorized individuals can access your files. It's designed for individuals and businesses who prioritize privacy and data security, offering a robust alternative to traditional cloud services. The platform encrypts files, their names, and other metadata directly on your device before they are uploaded, meaning Proton itself cannot access your data. Beyond secure storage, Proton Drive includes features like file sharing with password protection and expiry dates, automatic mobile backups for photos and videos, and desktop file syncing across Windows, macOS, Android, iOS, and web apps. It also integrates Proton Docs and Proton Sheets for private online document and spreadsheet editing and collaboration, protecting your work from data exploitation and AI training. Based in Switzerland, Proton Drive benefits from strict European privacy laws and is open-source, with its code regularly audited by independent experts.
