The App “Wi-Fi Privacy Police” looks dead.
Last update in F-Droid is from 2016-10-05
Last commit from Github is from 2017-08-05
The dev itself post that he have not much time: New version? · Issue #53 · BramBonne/privacypolice · GitHub and no answer from users which ask for activity: Project dead? · Issue #57 · BramBonne/privacypolice · GitHub
Also the App was never updated for Android 8+ and i wonder if the code is still secure.
