Most browsers include a feature to identify the location of the user, similar to the way that a mobile phone carrier can detect the current location of their subscriber or the way that a mobile phone with GPS capability can find you and other locations. Geolocation is a feature in new versions of web browsers. It can be found in other applications that will try to assess or determine the user's location to provide customized services.
The first time you visit a website that requests geolocation information, the browser should display the Google Location Service’s terms and conditions. You will have the option to allow or disallow the browser from sending your location data. The screenshot at the left is an example how a website asks for your location information.
What is sent to websites that requires location data?
Your IP address is sent to the website that requests the location information. If you are using a laptop or other wireless-enabled device, the MAC address and signal strength can be sent as well. The browser should not save location data, nor are any cookies generated by websites that request the location information. Other websites will not be able to retrieve it, but it’s recommended to regularly clean your temporary Internet files, browsing history and stored cookies.
Most privacy-conscious users do not want to have geolocation enabled. This guide will cover how you can turn Google Chrome geolocation off and how you can turn off geolocation in other popular browsers.
