The Who Is Tracking My Phone app is the best way to track the data usage and the location of your smartphone. It will help you to know what apps may be collecting data and permission about your location even when you're not using them and damaging battery and monitoring your every activity. It also allows you to see the history of all installed apps usage for today, last 7 days, and last 15 days etc. The user can simply add a set of permissible applications that he/she allows to use his/her location. The Who Is Tracking You will continually monitor the state of these applications, and send the user a reminder if his/her GPS is on and he/she isn't using any of them.
