When you search for Gold Word opponents using Facebook, the following information is requested from Facebook:

• the full list of your Facebook friends
• which friends have Gold Word installed
• which device(s) each friends uses to run Facebook

The above information is used to display your friend list on the Match Play page, and to allow you to filter the list to show only Gold Word users, or to show only users with devices that can run Gold Word. The only portion of this information that is ever stored is the names of friends with whom you play Gold Word; their names are stored so that Gold Word can provide a list of recent opponents to make it easier to play rematches. Gold Word does not ever share any of the information it retrieves from Facebook.
