If you are running Android and you are using a package by Google or your vendor that you neither want or are able to remove or disable, try blocking this component/tracker:

com.google.android.gms.measurement.AppMeasurementService

It [s]ets whether analytics collection is enabled for this app on this device. This setting is persisted across app sessions. By default it is enabled.

I do it with AppManager.
