Privacy Policy

1. Information we collect

To complete event registration and review, we collect: your account phone number and login password, team name and affiliated organization, contact email, the names and ID numbers of the captain and team members, the supervising teacher's name and contact details, and the records generated during registration submission and review.

2. How the information is used

The information above is used only for eligibility review, public rosters, result statistics and event communication. It is not used for any other purpose and is never sold to third parties.

3. Storage and protection

Sensitive personal information such as ID numbers is stored encrypted in the database, operation logs use a hash chain to prevent tampering, and exporting rosters from the admin console requires role-based authorization and leaves an audit trail. After the event, ID numbers of published teams can be cleared from the admin console.

4. Your rights

You can download a copy of all the data you submitted in "My Account", and you may request account deletion; deletion requests that involve a submitted registration are handled by the organizing committee after manual verification.

5. Contact us

If you have any question about how your personal information is handled, please contact the organizing committee through the "Contact" page.
