GPS is reading signals from satellite not broadcast so only danger is general location gathering danger for all phones, even to some degree dumb phones from cell tower interaction. GrapheneOS blocks a lot of google phoning home with location stuff. The social media stuff, especially Meta products which spy the most, should not be used if you care much about privacy, especially not Facebook, or using same FB idea on their other projects. You could perhaps use it in a profile but I would be very surprised if it didn't at least associate phone IMEI with the data Meta normally collects.
