com.google.android.gms.policy_sidecar_aps
Not sure what purpose it has, but it gets some network and phone data and connects to some Google domains, but never on its own; it has no permissions and never runs on its own, it likely exists as a helper package for other Google services.
Doesn’t seem to exist in newer versions of Android; it’s not in Android 11, but it is in 9.
Needs a Google Account and Google Play Services to work.
Given its name it could be related to Android auto?
Seems safe to remove, noticed no breakage (didn’t test Android Auto though).
