This is a very simple application
Just lock/hide your installed applications

The first time you run the app, it asks for the new password.
After this you never can change the password (the only way is deleting /home/user/.config/cepiperez/applocker.conf file)

The way it hides applications is simple: rename app.desktop to app.desktop1 in /usr/share/applications/hildon folder.

If you want to remove the app remember to unlock all apps!
