This is a realy a light and simple app.After a third failed login it will take a picture and store in the gallery. The idea behind this app is not security, but rather to see who is messing with my phone at home. It is not going to send an email or a text message. It will not find your phone location. Like i said, this a light app and it does not require internet permission. So all you need to do is install it. there is no setting to configure. So if you think somebody messed with your device, just open the gallery app and see who done it. it will only run when someone enter a wrong pass code a third time. it will take a picture discreetly. it will not run in the background and will not use batteries at all.
