Calculator Vault Apps: The Hidden Photo and Video Storage Parents Miss
Published April 18, 2026
There is an entire category of apps designed to look exactly like a calculator but secretly store photos, videos, and files behind a PIN. When you open them, you see a working calculator. Enter a specific code and it opens a hidden vault. The most downloaded ones are: Calculator+ (also called "Calc+"), Secret Photo Vault, Private Photo Vault, and Keepsafe. They have millions of downloads and appear in the top charts of the App Store and Google Play. They're particularly common among teens who want to store photos they don't want parents to see. The apps are nearly impossible to identify by icon alone — they look identical to the default calculator.
What to do:
Search your child's phone for: "Calculator+", "Calc+", "Keepsafe", "Private Photo Vault", "Secret Photo Vault". On iPhone, swipe down on the home screen and search each name. Check if your child has more than one calculator app — the real one and a vault version.
