Keeping a complete search history on your device and making it available to every future version of Google Maps software to do whatever it wants seems kinda bad

Keeping a complete search history on your device and making it available to every future version of Google Maps software to do whatever it wants seems kinda bad if you don't trust Google? Then again, you upload any address you use to Google anyway, where it could in theory be recorded server side, so I guess we're trusting that Google won't break some of their promises regardless.
