Does Google keep track of the pages I'm viewing or the books I read?

In order to protect copyrighted books, we only allow Google Books users to view a limited portion of the book. Enforcing these limits requires us to keep track of our users' page views. We don't associate your searches or the pages you view with any personally identifiable information about you, such as your name and address, unless you log in with your Google Account. However, to enforce limits on user page views, we do associate some non-personally identifiable information (IP address, cookies) with the books and pages that you've viewed regardless of login. We keep this data for a limited period of time to enforce viewing limits. As always, we encourage you to read our Privacy Policy to be fully informed about how your confidentiality is protected.
