This is used to detect when an app is launched or closed and allows you to change the filter actions for each app.

This information is not stored or shared.

This app needs to run a service in the background to detect which app has started.

(If you do not do this, services running in the background will be forcibly terminated, and the app will not operate properly.)

Please drag this app a little down from the recent apps history and lock it.
