Privacy Finder is a privacy-enhanced search engine. Once you state your privacy preferences (low, medium, high, or custom), the search results are ordered based on how their computer-readable privacy policies comply with your preferences. A privacy meter with four green boxes indicates that the website complies with all your privacy preferences. Websites that do not comply with some or all of your preferences will have privacy meters with fewer than four green boxes. The number of green boxes that are missing are proportional to the number of preference conflicts between the website's privacy policy and your privacy preferences. The absence of the privacy meter means that a valid computer-readable privacy policy, known as a P3P policy, could not be located.
