Do you know who is watching you through your location services?
While there are some privacy-focused apps out there that don’t track you by default (or at all, for that matter), the general rule is that location tracking is on unless you disable it yourself.
Ultimately, it’s in the best interest of app developers to have your location data. The apps are “free” simply because the data you provide is valuable to them, and that’s not going away. Thus, it falls onto users to practice due diligence and opt out of this data collection.
