Web APIs (navigator, geolocation, history)

The main privacy concern is revealing the user's precise physical location: 1) The Geolocation API can provide highly accurate location data, sometimes within a few meters, 2) This physical location data is personally identifiable and sensitive information, 3) It could potentially be used to track individuals, their habits, or their routines, 4) This is why browsers require explicit user permission before allowing access, 5) The permission prompt typically explains what site is requesting location and why, 6) Users have the option to deny, allow once, or allow permanently, 7) Browsers typically show indicators when a site is accessing location data, 8) Modern browsers also increasingly limit access to location data in inactive tabs or background contexts.
