Related to OPs question if I have both Gboard and Gcam in the main profile, all with network revoked and no Gplay services installed, would there be any data sharing? I always assumed it requires another Google app with network access for this to be a problem.
I tried my best to use Swiftkey but I'm having hard time getting used to it. Currently using heliboard however I would like the Swype function which I think Gboard gets it right all the time. Of course, I could install the swipe library but since that is closed source it gives me a pause.
