Features With this extension, we give you tools to better understand your browser fingerprint. Keep track of your fingerprint's evolution through time! With your very own personalized timeline, you can retrace all the changes that took place since you install the extension. The addon will notify as soon as a change is detected. But that's not all! We plan to add in the near future new features to improve your anonymity with regard to fingerprinting.

Our mission The website is launching its own extension to further improve our understanding of browser fingerprints! With more than 100,000 collected fingerprints on our website (and counting!), we learned a lot about the current diversity of fingerprints. However, a small piece of the puzzle is missing: an analysis of their temporal evolution. We do not know how they evolve and how fast they can change with time. This extension is the answer. With it, you help us collect daily data on your fingerprint to shed light on this relatively unknown subject.
