Ratings and reviews

Love(d) the app. Worked like it should without a hitch every time.... Then phone suffered a catastrophic event. Factory reset and BOOM.... found out that the only way to restore ANY of the previously purchased functionality was to restore from a backup. That nugget of info was literally buried in the help section and quite useless post reset. I might have considered repurchasing the lost functionality if the buried and effectively hidden gotcha clause didn't come across so shiesty. SAD.

This app just might be my saving grace 🙏 I have factory reset twice and even started fresh but some how someone has still managed to remotely access, change everything I do and export apk files after accessing my camera and microphone. I shut off bluetooth, and location and they managed to turn it back on and make it unchangeable. As well as remove google maps all together. The amount of control is insane and if this doesn't work I'm burning every device in my front yard. (Not kidding)

Very good. Stops all apps & system from recording. The camera app cannot even start when the Camera lock is on. The Mic Lock can block recording while talking on the phone. I keep the Internet lock always ON, except when I need internet to email or browse. This blocks data & location tracking, and also blocks all those ads in other apps. I've used this app for 3+ years & haven't had any issues. There are No ads in this app. Only 1 lock is free. This System lock can save battery and block some things, so it is useful by itself. Other locks cost money. Worth the price for better privacy to me.
