Security
We can't read
your data.
Not "we promise we won't." We can't. Everything is encrypted on your machine before it leaves, with keys only you hold.
End-to-end encrypted
AES-256 on-device before upload. Ciphertext is all that ever travels or rests on our storage.
Zero-knowledge keys
Your key is derived on your device and never transmitted. Lose it and even we can't recover your data — that's the point.
Open formats
Your backup is readable with standard open tooling and your key. No lock-in, ever — you can walk away with everything.
