Privacy-focused search engines are designed to protect users' personal information while they search the web. Unlike traditional search engines, they do not track user activity or store search history, ensuring that searches remain confidential. This approach helps users maintain their privacy and reduces the risk of targeted advertising based on their search behavior. These search engines often use alternative methods to generate revenue, such as donations or non-intrusive ads. Popular examples include DuckDuckGo and Startpage, which prioritize user privacy and provide a secure browsing experience without compromising on search quality.
