I’m not an expert but I do not believe GPS transmits much data by itself. It would be what your service provider, apps, websites do with that GPS derived location data.

That is intentional. It provides a reasonable approximation of age while maintaining privacy. The big gaping hole someone pointed out to me is who gets to determine what is blocked?

I think those two things are more harmful to the development of young minds and their mental wellbeing than anything NSFW.
