Privacy Policy
How this site handles information. This policy applies to en.mathleague.org.cn. Last updated May 2026.
This site is an independent, informational guide. We keep the information we handle to a minimum, and this policy explains what that means in practice.
What we collect
You can read everything on this site without creating an account or giving us any personal details. Like most websites, our hosting and content-delivery providers may automatically record standard technical information — such as your browser type, approximate region, and the pages you visit — for security and to understand general traffic. This information is not used to identify you personally.
Cookies and analytics
We may use privacy-respecting analytics to count visits and see which pages are useful, and our content-delivery network may set basic functional cookies. We do not use advertising trackers, and we do not sell or rent any data to anyone.
Contacting us on WhatsApp
If you choose to contact us by scanning our WhatsApp code, that conversation takes place on WhatsApp and is governed by WhatsApp’s own privacy terms. We use what you tell us only to answer your question. We do not add you to marketing lists without your agreement.
External links
This guide links to official and third-party sites, including mathleague.com. Once you leave this site, the privacy practices of those other sites apply, and we are not responsible for them.
Children
This guide is written for parents, teachers, and students. We do not knowingly collect personal information from children through this website; any enquiry on a child’s behalf should be made by a parent or guardian.
Changes
We may update this policy from time to time and will revise the date above when we do. If you have a question about privacy, you can reach us through the WhatsApp code on our Contact page.
