None of this is new to Ixquick.com. Although a relatively small search engine we are considered the industry leader when it comes to search Privacy. As a rule, we delete our users' IP addresses within 48 hrs and do NOT store any unique user ID cookies.
This has been our practice since June 2006, when we became the world's first search engine to take this pioneering step. Our service is available today.
Please feel free to contact us for additional information.
