Proton Drive

Proton Drive gives you a highly secure space to store, share, and sync your most sensitive files. Unlike traditional storage providers, it uses end-to-end encryption, meaning not even Proton can see what you upload. You can access your data from any device while knowing your privacy is protected by Swiss law and open-source, audited code.

You can easily organize your digital life with folders, automatic photo backups, and secure file sharing links. It is built for anyone who prioritizes privacy, from individuals protecting personal photos to businesses securing confidential documents. You get a seamless experience that integrates with the broader Proton ecosystem, including Mail and Calendar, to keep your entire digital footprint private.
