⭐ What Is Calculator Photo Video Vault?
Calculator – Photo Vault & Vid is a privacy protection app that hides photos and videos inside a secure vault disguised as a calculator. To anyone else, it simply looks like a basic calculator and works like one. But only you know the secret password that unlocks the hidden vault.
The vault encrypts your files, meaning even if someone finds the hidden folder, they still cannot open your images or videos.
It is mainly useful for:
- Protecting private photos
- Hiding sensitive work documents
- Keeping family videos secure
- Preventing accidental access by children or friends
- Storing important images safely even if the device is shared
