I cannot recommend Duck Duck Go's
app tracking privacy suite for android enough.
Simply install #DDG you don't need to use it. Open up the settings and switch on 'App Tracking Protection' then forget about it. It's that simple. You can see which apps have been trying to harvest your data easily, who what and when, it works in the background across ALL your phones installed apps.
Done and dusted π
Yes there are better ways but this is by far the simplest.
