Proton Drive

Proton Drive provides end‑to‑end encrypted cloud storage that lets users back up files, access them from any device, and share them securely. Files are encrypted on the client side, so only the owner and designated recipients can decrypt the data; even the service provider cannot read the contents. The client synchronizes local folders with the cloud, maintaining up‑to‑date copies across macOS, Windows, Android, iOS and web interfaces.

The application supports sharing with optional password protection and expiry dates, allowing controlled distribution of documents, photos, and spreadsheets. Integrated tools such as Proton Docs and Proton Sheets enable private creation and collaborative editing of text and tabular data, while automatic mobile backups keep photos and videos safe and organized.

Designed for individuals and teams that prioritize privacy, Proton Drive operates under Swiss jurisdiction and complies with European privacy regulations. The software is open source, stable, and distributed for macOS as a core component of the broader Proton ecosystem.
