And you already said it, the users, me, everyone, we are watched by the services of the big companies like google and its applications: Google Maps (timeline), Google Photos, etc.

These companies abuse the ignorance of users and provide incredible services in exchange for information in real time, all by data mining, marketing, etc., as proposed to solve or compete with G Maps, Facebook and others that are outside of a hardware or device in specific.

I would say my friend, your project is really crazy and ambitious, go ahead.
