What the calculator vault is for

This is a calculator app built to hide private content. Its front screen looks and works like a standard calculator, and the vault sits behind it. The developer, Technozer Solution, describes it as suited to people who want photos, videos, files or apps kept out of view on their phone.

The listing describes the calculator as working like a real one, so anyone looking at the phone sees an ordinary calculator. The hidden content is only reachable through the app itself.

Hiding photos and videos from the gallery

Pictures and video can be moved out of the main gallery and into the vault. According to the listing, that content is encrypted and stored in the app rather than left in the regular photo library.

This is the core use the listing points to. It is aimed at keeping sensitive images and clips from appearing in the gallery that other people see when they pick up the phone.

Keeping files and documents private

Beyond media, the listing says the vault can also hold files and documents. The developer names documents among the content it protects, so it is not limited to photos and video.

The listing does not break down which file types are supported, so the wording of the feature is the only detail available here.

Locking and hiding other apps

The app can hide other apps on the phone, and the listing names social apps as a typical example of what someone might lock. Hiding an app keeps it out of sight, and locking it keeps it closed behind the vault.

Both features sit alongside the photo and file vault, so the same calculator front covers media, documents and apps.
