geolocation - Getting User's Location Without Permission -


this website finds location reasonable presicion. if use mobilephone website finds exact location. if possible without asking permission why of them asks me before getting location? isn't makes personal security vulnerabilities?

from same page gave us:

webkay uses google geolocation api locate you. educated guess , never accurate gps location. accuracy depends on location , on connection type. if on mobile network expect error of 50km. example tries demonstrate how accurate website can guess location without asking permission access gps.

a site needs permission, if wants enable device's gps. also, without permission, guessed location heavily dependent on mobile carrier signal , ip address. if in location lot of mobile towers, location (obviously) more precise.

a site can use information near mobile towers around triangulate position , guess are. think of mesh.

for example: using computer write , location easy ~100km off, because has ip adress estimate location.
