Feds are buying data about people from a company that gets it from several apps

If you are an app developer, and you sell your app data to some company, it can be used this way.

Some of these apps are for things like gay dating (Bro) and religious prayer and study (Muslim Pro, an app that notifies people 5 times per day it's time for them to pray) (Full Quran, an audio book of the Quran), as well as one where people upload their faces and do virtual makeup on it (Perfect365).
