Retrieving actual positions
For each web user who agrees to share their position, Geoloc+ looks at the actual final position.
If they refuse
When the user doesn't give the browser access to their precise position, only the IP address is left to try to locate them. Geoloc+ goes further and requalifies this position to make it more precise. To do this, it determines their theoretical position in relation to the history of people who consented.
If it's impossible
If Geoloc+ is unable to determine the web user's position, their IP address is disqualified (around 10% of cases).
