About Cover Your Tracks

Cover Your Tracks runs a test in your browser and shows how trackers see it, with an overview of the characteristics that make your browser unique and identifiable. An option runs the test against a real tracking company.

It is a project of the Electronic Frontier Foundation, and a guide on the site explains how fingerprinting works. The site says only anonymous data is collected. It suits anyone checking whether a browser, extension or privacy setting actually reduces tracking.

Strengths

  • Shows which browser characteristics make you identifiable
  • Option to test with a real tracking company
  • Explanatory guide on fingerprinting

Limitations

  • Diagnoses tracking exposure but does not block anything
  • Results reflect one browser and setup at a time
