DuckDuckGo is a search engine that builds its search index using its DuckDuckBot crawler, indexing WikiPedia, and through partners like Bing. The search engine does not use any data from Google.
What makes DuckDuckGo stand out is that they do not track your searches to build a user profile or share any personal or identifying data with third-party companies, including ad networks.
"Each time you search on DuckDuckGo, you have a blank search history, as if you’ve never been there before," DuckDuckGo explains in their privacy blog.
I've seen the same on my own website stats where Duck Duck Go is not even leaking what search terms are being used. I see nothing. Most browsers allow you to easily set DDG as the default search engine and that's all that needs to be done. I've been using it exclusively for the last few years.
