There is no proof that Chrome secretly tracks anything, and if it did such proof would not be that hard to find.

Google has included a lot of user tracking abilities in Chrome. Chrome sends details about its usage to Google through both optional and non-optional user tracking mechanisms. See details here: Google Chrome - Usage tracking
