DuckDuckGo

DuckDuckGo is a privacy-focused search engine launched in 2008 that does not track users, store IP addresses, or personalize search results. It offers unique features like !bang commands for direct searches on other sites and is the default search engine in the Tor Browser. For maximum anonymity, DuckDuckGo also runs an official .onion version that allows secure searching within the Tor network. The company proves that profitability and privacy can coexist, relying on keyword-based ads rather than personal data collection.
