About registration & your email

Registration requires a valid email address for a one-time sign-in code — no password is created or stored. Prefer not to use your primary address? A disposable address is perfectly fine. Services such as mail.tm, temp-mail.org, or guerrillamail.com issue disposable addresses instantly and remain active for several days — long enough to receive your sign-in code and any prize notification.

Your email is used solely to deliver your sign-in code and, if you win a raffle prize, to contact you. It is not shared with any third party, not used for marketing, and will be permanently deleted within 30 days of the event's conclusion. Only your chosen handle and team name (if you opt in) appear on the public leaderboard.
