App Lock

AppLock is a lightweight app that lets you lock almost any type of file on your Android. The most basic feature locks your applications so nobody can access or uninstall them, but you can lock photographs, videos, and even contacts and individual messages.

The application works in a very simple way. First, you have to create a numeric password to unlock the application you want to protect. From that moment on, every time that app is opened, it will require you to insert the password you have defined. Even if another user tries to uninstall it, this password window will not allow it.

The main thing is that there is no any hidden feature or activity because we user privacy is most important for us
