Google Watch

If this is true then its just not right . Shouldnt Google be telling their users what all information they persist about that user. ? Though I am not sure about the authenticity of this claim. As this comes from other end of the spectrum - Google Watch.

For all searches they record the cookie ID, your Internet IP address, the time and date, your search terms, and your browser configuration. Increasingly, Google is customizing results based on your IP number. This is referred to in the industry as "IP delivery based on geolocation."
