Hi, I work for DuckDuckGo and wanted to clarify that We absolutely do NOT doing any fingerprinting whatsoever. Our privacy policy is very clear on this: “We don’t collect or share personal information.” DuckDuckGo Privacy
We use a variety of browser API’s to deliver a search experience that is competitive with Google’s. Many “fingerprint” protection extensions take a scorched earth approach, blocking any browser API that could be exploited by a bad actor.
