CTRL VAULT — THE ZERO-KNOWLEDGE PHOTO VAULT FOR IPHONE

What could go wrong. What CTRL Vault does.

Each risk on the left, the protection that answers it on the right.

Risk 01Your phone is stolen
AES-256-GCM · pattern lockEvery photo stays encrypted. Without your pattern it’s unreadable data.
Risk 02You forget your pattern
12 recovery wordsYour words find the vault and let you set a new pattern. Your photos stay put.
Risk 03Someone screenshots or records
Capture blockedScreenshots come out blank and screen recordings black.
Risk 04Someone makes you open it
Hidden vaultsEach pattern opens its own vault. A wrong one opens an empty vault, and there’s no list to find.
Risk 05A company gets hacked
No server · no accountThere’s no CTRL Vault server holding your photos, so there’s nothing of yours to steal.
Risk 06You leave it open

Encryption meets simplicity.

At last, privacy & convenience in harmony.

Your pattern + a device salt in the Keychain → PBKDF2 → pattern key. It unwraps a random 256-bit master key. Every photo is sealed with AES-256-GCM in 1 MB chunks, each with its own 96-bit nonce. Nothing leaves the phone.

We help people keep what matters private.

Not sure what it all means?

That’s OK. We already locked it down.

Draw a pattern. Write down 12 words. Add photos. The rest is math.

AES-256 · ROUND 01/14

One pattern. One vault. Nobody can count them.

A wrong pattern opens an empty vault. There is no list of vaults to find.
