At DuckDuckGo, we do not collect or share any personal information. That's our privacy policy in a nutshell. To improve our products we had to create a completely anonymous way to figure out how DuckDuckGo is being used.

Any requests to this domain -- improving.duckduckgo.com -- are part of this anonymous experiment engine. You can learn more about how this technology works and how it was designed to protect your privacy here.
