GravyScanner : a FOSS Android app that reveals installed apps involved in Gravy Analytics data breach

GitHub - steffandroid/gravy-scanner: Android app that reveals installed apps which may be leaking your location data via Gravy Analytics

For the out of the loop, but also lazy:
Additional info for the lazy: the name of the company is "Gravy Analytics", hence the name "Gravy Scanner" for this app. It's a large data broker, and they don't bother with pesky little details like "informed consent".
Anyway, they got hacked a month ago, and the hackers threatened to publicly release all the data.
