DuckDuckGo

DuckDuckGo is an Internet search engine that emphasizes protecting searchers' privacy and avoiding the filter bubble of personalized search results. DuckDuckGo distinguishes itself from other search engines by not profiling its users and by deliberately showing all users the same search results for a given search term. DuckDuckGo emphasizes getting information from the best sources rather than the most sources, generating its search results from key crowdsourced sites such as Wikipedia and from partnerships with other search engines like Yandex, Yahoo!, Bing, and Yummly.

The company is based in 20 Paoli Pike, Paoli, Pennsylvania, United States, in Greater Philadelphia, and has 21 employees. The company name originates from the children's game duck, duck, goose.

Some of DuckDuckGo's source code is free software hosted at GitHub under the Apache 2.0 License, but the core is proprietary. On 21 May 2014, DuckDuckGo launched a redesigned version that focused on smarter answers and a more refined look. The new version added often requested features such as images, local search, auto-suggest and more.
