Zero-knowledge cloud storage. Files are encrypted on your device before they ever reach our servers — we literally cannot read them.
Trusted by teams at
Everything you love about the cloud, minus the part where someone else can read your files.
Files are encrypted on your device with keys only you hold. We store ciphertext, nothing else.
Windows, macOS, Linux, iOS and Android — your files everywhere, in real time.
Roll back any file up to 180 days. Accidental deletes and ransomware are reversible.
Share links with passwords, expiry dates and view limits — without exposing your keys.
Only changed blocks are uploaded. Huge libraries stay in sync without eating bandwidth.
Built on audited, open cryptography. Export your data anytime, no lock-in.
Sign up and your encryption keys are generated locally in seconds.
Drag in documents, photos and backups. They encrypt before they leave your device.
Open, edit and share across all your devices — always end-to-end encrypted.

Native apps for Windows, macOS, Linux, iOS and Android, plus a web client and a command-line tool.
