Velcrypt features
How your vaults are protected
The unlock model and the cryptography behind it.
Pattern lock
Unlock with a pattern drawn on a 5×5 grid. At least 6 dots and one turn; 8–12 dots recommended. No Face ID, by design.
Read →Hidden vaults
Every pattern is its own vault. No vault list, no error for unknown patterns, and room for a believable decoy vault.
Read → Coming soonDuress pattern (coming soon)
Coming soon to Premium: a special pattern that opens a chosen vault and silently removes access to the others.
Read →Encryption
AES-256-GCM per file, keys derived from your pattern with PBKDF2-HMAC-SHA512 and HKDF, plus iOS Data Protection.
Read →Offline, no account
No account, no servers, no uploads, no content analytics. Everything stays on your iPhone, with an honest trade-off on recovery.
Read →What you can keep inside
Bring in photos, videos and documents, then organise them privately.
Hide photos
Import photos as encrypted copies, clear the originals and Recently Deleted, then browse them in albums with zoom and swipe.
Read →Hide videos
Import videos as encrypted copies, play them inside the vault, and clear the originals without running out of storage.
Read →Private documents
Import PDFs, scans and ID copies from Files into an encrypted vault, view them offline and export only when needed.
Read →Auto-lock
The vault locks when the app goes to the background, after a delay you choose, and stays blank in the app switcher.
Read →Albums and viewer
Albums in every vault, multi-select and move, a zoom-and-swipe viewer, and an export that you control.
Read →Frequently asked questions
Does Velcrypt use Face ID?
No. Velcrypt deliberately has no Face ID or Touch ID unlock, because a face or finger can be used without your consent. The pattern exists only in your memory.
How many vaults can I create?
Every distinct pattern opens its own vault. Exact limits for the free version are not final yet; more vaults are one of the planned Premium items.
Does Velcrypt upload my photos anywhere?
No. Velcrypt has no account and no servers. Vault content is encrypted and stays on your iPhone.
Well Encrypted. Truly Private.
Draw a pattern, open a private vault. Your photos, videos and documents stay encrypted on your iPhone, with no account and no cloud.
Launching soon for iPhone (iOS 17 or later). Free version, optional Premium.
