Are you worried about the photos you take and the videos you record being seen by others? Are you concerned about the personal information that is stored on your device? If you are, then you are at the right place.

With our Calculator Lock, no one will be able to see the photos and videos you take or the information you store in your device. This app allows you to take photos and videos, as well as hide them, so that no one will be able to see them unless you want them to.

You can also have a secret calculator, which will allow you to do calculations without anyone knowing about it. You can even have a second calculator, which can be used for different purposes.
