What does “encrypted on your iPhone” mean?
Your files are encrypted before they are stored. Privacy is built into how Sanctum works, not promised in a policy.
Pattern encryption
Draw a shape on a 5×5 grid. 600,000 rounds of PBKDF2 and a secret kept in this iPhone’s Keychain turn it into the key that unwraps a random 256-bit vault key.
Learn moreRecovery code
Every vault gets a 256-bit recovery code. It opens a separate encrypted copy of the vault key, so a forgotten pattern never means lost photos, and nobody else holds a key.
Learn moreHidden vaults
Each pattern opens its own encrypted vault, and there is no list of vaults anywhere. The screen shows only the vault you opened; what storage can still reveal is documented.
