Privacia is a non-profit organization, based in France, that develops open source software projects such as Privacia, a privacy search engine, OpenTor, and others.

Privacia has an open source client and a privacy policy that states that it does not store any information about the user, nor does it connect users to any other third-party services. The privacy policy of Privacia.org states: "The service will be used for informational purposes only. It is a search engine that pulls information from over 400 other sources, including Bing, Yahoo, and Wikipedia. Users can specify a search for images, videos, news, meanings, or shopping. The service will not connect to any other third-party services. Privacia will not collect or share your personal information."

If you're interested in a specific topic, you can choose a subtopic or a topic and enter it. The service will return the results for that topic. Searching for shopping will return results from eBay, Amazon, and other online stores. Searching for images will return results from Flickr, Instagram, and other image websites. Searching for news will return results from Google News, and searching for meanings will return results from Meaning.net. The service also has a "refine" function that allows you to narrow the search by choosing age, location, or content of results.

In addition, the service offers an "Adult Filter" and an "Search History" filter that can be used to control the age and the amount of time since the results were seen.
