  • The newsletter stores your email address, but it is only visible to the administrator of the newsletter, namely, me (Michael Hartley, aka "Dr Mike"). I have no intention that this site will change hands, but if it did, newsletter subscribers would be informed, invited to subscribe to a replacement newsletter, and then the old list cleaned out.
  • Certain games, namely MathGolf and Mathteroids, keep track of high scores. Players are invited to enter their name, school and country before playing. If they do well at the game, this information will be displayed on the website. If the information is not entered, it is displayed as Anonymous, from No School, No Country. At my discretion, and if I am able to identify it from the information given, I may insert a link to the winner's school into the high scores table. The IP address of winners is also stored, but not made public.
