This site will store your login information and browsing activity for the purpose of providing you with the service of this book only. If your account is connected to a course you are enrolled in then this will be stored too. 

No individually identifiable information will be sold or passed to any third party unless legally compelled by a lawful authority (it’s hard to imagine why a law court, etc would want to know about your access to a textbook, but there it is).

At times we might show instructors aggregated statistics on how engaged their students are, as a group. We will not show them information that would make it possible to identify the activity of individual students.

You may request that we delete any information we store on you at any time. If you ask us to delete your login credentials then it would obviously not be possible to grant you access to the site anymore.
