Determining who is responsible for showing ads on the websites we visit or who collects data from the mobile applications we use daily can be overwhelming. That information is already partially public, but it is not easy to interpret and traditionally much of it has remained under the control of large advertising platforms.

A new free and powerful service called DecryptAds is changing that situation. The tool extracts and correlates programmatic advertising data, allowing users to quickly and easily discover a wealth of information about the entities tracking them.
