What does zero-knowledge mean?
It means we have zero knowledge of your file contents. Encryption keys are generated in your browser, never sent to our servers, and embedded only in the link you share. Not even we can decrypt what you store.
Keys stay with you
AES-256-GCM keys are generated and stored only in your browser. We never see them.
Legally protected
We only store encrypted data. No one can access your files — not even us.
No trust required
You don’t have to trust us with your data. The math protects you, not our promises.
