Ask Mrs. Saxophone up there. Something about tracking? You call it tracking. I call it spyware. Same difference .
Oh yeah, that's why I switched from Chrome to CD.
"Chrome sends details about its usage to Google through both optional and non-optional user tracking mechanisms."
1. Installation - Randomly generated token included in installer. Used to measure success rate of Google Chrome. (not optional)
2. RLZ identifier - Encoded string, according to Google, contains non-identifying information how Chrome was downloaded and its install week. Used to measure promotional campaigns. (partially optional)
3. clientID - Unique identifier along with logs of usage metrics and crashes. (optional)
4. Suggest - Text typed into the address bar (optional)
5. Page not found - Text typed into the address bar (optional)
6. Bug tracker - Details about crashes and failures (optional)
Some of the tracking mechanisms can be optionally enabled and disabled through the installation interface and through the browser's options dialog. Unofficial builds, such as SRWare Iron and ChromePlus, seek to remove these features from the browser altogether. The RLZ feature is not included in the Chromium browser either.
In March 2010, Google devised a new method to collect installation statistics: the unique ID token included with Chrome is now only used for the first connection that Google Update makes to its server. This sole remaining non-optional user tracking mechanism is removed following the server ping.
