Self-claimed anonymous analytics have repeatedly failed in the past: you've been using this for at least two years, why didn't Cliqz release a paper before then on it? Or even explain what it is? Or a mention on your site of it? I don't want to dislike Cliqz, what it says it's doing is cool. However, given the financial incentives involved, the verify step of "trust but verify" is more essential than ever.
