How Location Tracking Works Over the Internet

The fact that a company knows your location over the Internet is just a fact of life unless you are connected via some sort of proxy and block JavaScript code that might bypass it. Despite the fact that you can’t ever hide (barring the use of TOR or VPNs) from the services you come into contact with on the Web, it’s still useful to know the methods that they can use to track your location. This kind of knowledge, in the end, will empower you to make better decisions about your privacy.

Your Router’s IP Gives It All from The Get-Go


It shouldn’t be much of a surprise to you that your IP can tell someone a lot about your location. In some exceptional cases, an IP address can give away the whereabouts of a device as accurately as GPS can. Internet service providers will often associate a range of addresses with one particular “sector” in their coverage area.

Although no one would be able to find your street address this way, it’s an easy way for advertisers to cater the ads you see to your region.

In the worst case scenario you’ll only be able to find out someone’s country through their IP. But that is still enough information for Google to know what language you speak, what TLDs (e.g. “.ro,” “.nz,” “.pl”) you’d prefer to see in search results, and how your ads should be displayed on websites that you visit and apps that you use.

GPS Will Pinpoint You Even When You Don’t Explicitly Let It


Apps often give you the option to disable GPS location tracking, but that doesn’t mean they won’t just go ahead and peek into your antenna anyway. If your antenna itself is enabled on your phone, expect at least one or two applications to occasionally turn it on to get your current location.

An application that has a built-in “disable GPS tracking” option can just ignore this whenever it wants. If you want to be certain that you’re not being tracked, you have to disable the antenna itself on your own.

GPS data is sometimes useful to companies that are attempting to understand where their users go during the day. By understanding their typical users’ schedules and movements, developers can better anticipate their needs in some context.

Your Cellular Antenna Also Gives You Away


If your phone has a SIM card in it, it’s always connected to a cell tower within 45 miles (~70 km). Once an app has the identification number of that tower (its cell ID), it already has an idea of where you are in the world. This can get more precise by querying other data such as the signal strength and the “round-trip time” of data exchanges between the device and the tower. A company could theoretically narrow your location down to a 15-meter radius using this method. This is also true of governments that use IMEI tracking.

If you use mobile Internet through your cellular carrier, you’re constantly sending signals to its tower, making it immeasurably easier to track you down. Disabling your cellular antenna would make your phone unable to send and receive calls or SMS messages, so there’s not really much you can do here.

In this particular situation, the only solution would be to get a “dumb” phone that has no modern applications installed on it.

  1. I do not have a cellphone in constant use. I only turn it on in case of an emergency. I do have a desktop computer with wi-fi and dsl service. My ISP is a national one that bought out regional/local providers over the 20+ years i have had the service; i have it set to filter spam and forward incoming mail to my gmail account. I get few emils sent directly to this original address. Google/Facebook “thinks” I live in either Nashville, TN or Pensacola, FL (not even close). My facebook page states where I reside. I constantly get ads from one or both these locations. I get notifications from via my gmail account that “someone” has logged on using an unknown browser from some place to which I cannot be connected. Checking the history in my firefox browser (which i have also used 20+ years) that unknown “someone always turns out to be me. I have the Kindle fire HD and there is no question with wunderground. Com or the Weather Channel as to my location. I guess i do not care what their problem is as they never answer any of my comments…

  2. Thanks for this nice information.
    Can someone else monitor my google account activity like maps & places etc.
    Other than google itself
