This Tool Unmasks the Shadowy World of Ads that Track Your Location

Ads can power all sorts of surveillance, from the relatively mundane like inferring someone’s age or gender, right up to harvesting their precise location data and selling this to the government. It can show what advertising brokers are operating on a particular website, and, more importantly, many other places those same brokers are operating.
