A photo you love. A scan of a personal document. A note that still means something. These things do not need an audience to be worth keeping. A private space gives them a home without making sharing the default.
Sign in with your passkey. Unlock this device with your vault pattern. Keep the recovery key somewhere safe: you need it to set up another device.
Revault encrypts file contents, names, and previews in your browser before uploading them. The service can still observe account associations, object counts, sizes, and timestamps. Encryption does not make every part of using a cloud service invisible.
A vault is only one part of a private life. Keep your devices updated, review browser extensions, and lock your screen. A compromised device or malicious frontend can read information while a vault is unlocked.
