What you get with Zero-Knowledge Vault
Encrypted before upload
Files are sealed on your device with keys derived from your passphrase, so data is unreadable in transit and at rest.
True zero-knowledge
We store only ciphertext. Without your key, nobody — including us — can decrypt your vault.
Private sharing
Share vault items with trusted contacts using per-recipient encrypted keys that never expose the underlying file.
