DuckDuckGoAt DuckDuckGo, we believe the best way to protect your personal information from hackers, scammers, and privacy-invasive companies is to stop it from being collected at all. That's why millions of people choose DuckDuckGo over Chrome and other browsers to search and browse online. Our built-in search engine is like Google but never tracks your searches. And our browsing protections, such as ad tracker blocking and cookie blocking, help stop other companies from collecting your data. Oh, and our browser is free — we make money from privacy-respecting search ads, not by exploiting your data. Take back control of your personal information with the browser designed for data protection, not data collection.
