Trexy remembers your search trails and anonymously shares them with others. This is what Trexy does!It doesn't do it behind your back secretly "spying" on you. We are totally upfront about its function and have gone to great lengths to design a system that balances the privacy concerns against the utility of a search engine that fulfills the trailblazing part of Vannevar Bush's Memex vision.
If you don't like what Trexy does - don't use it. But please don't call something "spyware" when it isn't!
