MetropleX if you remove the 'Network' permission you don't need to worry about the "tracker
MetropleX likely already knows this by now, but because this is 2 years later and it wasn't mentioned in this thread, for the sake of anyone else who ends up here: don't trust that turning off Network permission would prevent trackers from phoning home. Installed apps can communicate with each other if they are designed to do so, and could just share the tracking data to another app which does have Network permission (in Gboard's case, it would be reasonable to assume that it could communicate with Play Services or Play Store for instance, and you likely needed to keep Network permissions enabled for at least one of them.)
That being said, it's generally believed that Gboard respects the user's choice of opting out of data analytics, but this could change at any time. If your threat model requires it, you may not want to use Gboard until App Communication Scopes is ready. It will allow you to restrict inter-process communication for any app which should prevent Gboard from being able to leak data.
