Doesn't this already (somewhat) exist in open street maps? I feel like the answer here has to be open map data that anyone can download so there isn't a company to track the location in the first place.
A curious person could put Organic Maps on their phone, download city/region maps at home, then try to navigate somewhere using airplane mode with GPS on.
I disabled the pre-installed Google Maps app on my phone. Expecting Google to do things contrary to their business interest of collecting and selling data would be naive.
