DuckDuckGo (Duck Duck Go, Inc.) is an American privacy-focused technology company founded in 2008 by Gabriel Weinberg, headquartered in Paoli, Pennsylvania. Its flagship product is a search engine designed around strict privacy principles: it does not collect or store personal search histories, does not track users, and does not create user profiles or share data with third parties. The search results are generated from over 400 sources—such as Bing, Yahoo, Yandex, and its own web crawler—combined with crowdsourced data like Wikipedia, all without relying on behavioral tracking or personalized advertising.

Despite the absence of user-level tracking, DuckDuckGo generates revenue through contextual ads, using only the search query (not personal data) to serve relevant results and maintain profitability, a strategy proven sustainable since profitability was first achieved in 2014. DuckDuckGo’s product suite also includes browser extensions, mobile and desktop browsers, email forwarding (“Email Protection”), VPN services, and tracker-blocking layers. In early 2025, it introduced an AI-generated image filter feature to help users avoid synthetic content in search results, reinforcing its mission to offer privacy-first, transparent tools that empower user control and transparency.
