A real, working calculator that hides a PIN-protected vault for your private photos, videos, and notes — hidden in plain sight.

Why Calc+

A fully functional calculator on the surface, a private vault behind your PIN.
Store photos, videos, notes, and files with folders, favorites, and trash.
Your vault stays on your device by default — nothing uploads unless you turn on cloud sync.
Your unlock PIN is stored on your device and never transmitted.

Everything Calc+ needs for the App Store and Google Play: a privacy policy and support page that match what the app actually collects.

What we collect, why, and who processes it — plus a data-safety summary.
