Your photos should never be anyone else's business. Private Album locks photos and videos into a local vault with AES-256 encryption. Nothing is uploaded, nothing stays in plain text, and without your passcode no one can open it — not even us. GUARDED ON THREE FRONTS • Intruder Capture — someone enters the wrong passcode and the front camera silently snaps a photo as evidence. • Guest Passcode — when someone peeks over your shoulder, the guest passcode opens a separate, empty vault. • Calculator Disguise — the lock screen becomes a fully working calculator; your passcode goes in behind the equals key. SHOOT STRAIGHT INTO THE VAULT The built-in private camera encrypts photos at the moment of capture. They never touch your system photo library and leave no trace. RECOVER IT EVEN IF YOU FORGET Setup gives you a 12-word recovery phrase. Write it on paper and keep it safe — it is the only way to restore your photos, and nobody, including us, can do it for you. ALSO INSIDE • Unlock with Face ID or Touch ID • Recently Deleted items purge automatically after 7 days • Change the app icon to Calculator, Weather or Folder Your data stays on your device. The encryption key lives only on your phone, so we cannot view, recover or reach any of your content. Core encryption is free. Premium unlocks every feature, with weekly, yearly and one-time lifetime options.
