A free app for Android, by Rushikesh Kamewar.

The Privacy Dashboard app is a tool for tracking and monitoring the usage of your device’s hardware and software resources, including the location, microphone, and camera. The application shows the current usage of these resources, as well as the history of accesses to them. It is intended to help you understand the purposes for which your device is being used, and to determine which apps are accessing your privacy permission without telling you.

You will be able to access the app through a simple, intuitive, and easy-to-use interface. The app has a clear and simple timeline view of accesses to location, microphone, and camera.
