Optional crossword leaderboard

Updated 9 November 2026.

The controller is Max-TD Pty Ltd, reachable at hi@princ-solutions.com. Participation is optional; you can solve the crossword without joining the leaderboard. Publication and the confirmation email are based on your consent under Article 6(1)(a) GDPR. This consent is separate from advertising choices and browser storage preferences.

Only your chosen alias and solving time are public. Please avoid real names or contact details in your alias. We also store the puzzle version, measured start and finish times, consent version and timestamp, and confirmation time. Your email address is used only to confirm your request and is deleted after successful confirmation. A protected, pseudonymous email verification value remains to identify your fastest confirmed time; it is also personal data. Your address is not used for newsletters or advertising.

An unconfirmed request expires after 24 hours. Expired requests are removed on subsequent leaderboard requests. Confirmed entries are visible for no more than 365 days and are then removed on subsequent requests. A necessary session cookie is used for a timed run; unfinished runs expire after 24 hours. To prevent abuse, protected short-lived verification values derived from the IP address and email address, together with request counters, are retained for no more than 24 hours. The IP address is not stored in plain text for this purpose. Ordinary server logs are described in the general privacy policy.

The confirmation email contains a private link to withdraw your entry or pending request. Opening either link alone does not publish or remove anything: a further explicit action is required. Keep the withdrawal link. Withdrawal removes the entry and does not affect the lawfulness of earlier processing. If you lose the link, contact hi@princ-solutions.com. See our privacy policy for further information about access, correction, erasure and complaints.
