Your photos stay yours.
Selected images are copied into private app storage. The app has no photo server, account system, analytics, or ad network.
Private photo storage for iPhone
Plain sight.
Private space.
Calculator Vault works like a normal calculator. Enter your private code and press equals to open a local photo vault—no account, no ads, and no developer-controlled cloud.
Honest security: files use the iPhone app sandbox and are not separately encrypted by the current version.
Private when you leave.
The vault locks whenever the app leaves the foreground and obscures sensitive content in captures and app-switcher previews.
Clear about its limits.
Calculator Vault adds privacy and discretion, not a substitute for device security or file-level encryption.
The whole idea
A useful calculator on the surface. A quiet place for personal photos underneath.
