At 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. Our browser blocks YouTube ads, invasive web ads, and cookie pop-ups, reducing distractions and helping to stop other companies from collecting your data. While our optional integrated AI features, Search Assist and Duck.ai, are private and never use your data to train AI. 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. FEATURE HIGHLIGHTS Protect Your Searches by Default: DuckDuckGo Search comes built-in, so you can easily search online without being tracked.  Shield Your Browsing History: Our 3rd-Party Tracker Loading Protection blocks most trackers before they load, greatly exceeding what most popular browsers offer by default.  Chat Privately With AI: Duck.ai lets you have private conversations with 3rd-party AI models, anonymized by us and never used to train AI. Secure Your Email (Optional): Use Email Protection to block most email trackers and hide your existing email address with @duck.com addresses.   Block Ads: Our browser blocks YouTube Ads, and stops invasive trackers from loading on sites, effectively eliminating targeted ads. Automatically Enforce Encryption: Shield your data from network and Wi-Fi snoopers by forcing many sites to use an HTTPS connection.  Escape Fingerprinting: Make it harder for companies to create a unique identifier for you by blocking attempts to combine info about your browser and device.  Sync and Back Up Securely (Optional): Sync encrypted bookmarks and passwords across your devices. Clear your tabs and browsing data in a flash with the Fire Button. Banish cookie pop-ups and automatically set your preferences to minimize cookies and maximize privacy. And many more protections not available on most browsers, even in private browsing mode, including protection from link tracking, Global Privacy Control (GPC), and more.
