A user is bound by any changes to the Privacy Policy when he or she uses the Services after such changes have been first posted. In the event that the modifications materially alter your rights or obligations hereunder, we will make reasonable efforts to notify you of the change. For example, we may send a message to your email address, if we have one on file, or generate a pop-up or similar notification when you access the Services for the first time after such material changes are made.
