Tor hidden service[edit]
In August 2010, DuckDuckGo introduced anonymous searching, including an exit enclave, for its search engine traffic using Tor network and enabling access through a Tor hidden service.[44][45] This allows anonymity by routing traffic through a series of encrypted relays. Weinberg stated: "I believe this fits right in line with our privacy policy. Using Tor and DDG, you can now be end to end anonymous with your searching. And if you use our encrypted homepage, you can be end to end encrypted as well."[46]
Voice search[edit]
In 2011, DuckDuckGo introduced voice search for users of the Google Chrome's voice search extension.[47] DuckDuckGo includes "!Bang" commands, which give users the ability to redirect a search to specific websites.[48]
