Puzzles, games and the reader competition
You can play our puzzles without giving any personal data. To take part in the competition you choose a screen name; an e-mail address is optional and is used only to send you your personal link and to recover it, never for marketing. Your screen name appears in the public ranking only when you tick that box. The newsletter box is never pre-ticked: you are subscribed only when you tick it yourself. We store your screen name, your scores, badges and puzzle progress. To prevent abuse we keep a non-reversible code of your IP address with each entry for at most 30 days. Your personal link is a random code; only a hashed version of it is stored. You can change your screen name and delete all your game data at any time on your personal page. Players who have not played for 24 months are deleted automatically. The legal basis is the performance of the service you request (taking part) and, for the newsletter, your consent.
