Privacy policy
This policy explains what personal data we collect when you visit this website, why we collect it, how we use it, who we share it with, and the rights you have over it.
1. Who we are
2. What we collect
Automatic collection
When you visit the site, we automatically collect: pages visited, referring URL, browser type, approximate country (derived from your IP, never the IP itself stored), and the timestamp of your visit. This is how analytics works on virtually every website.
3. Why we collect it (purposes)
4. Legal basis
5. Cookies and similar technologies
We use a small number of cookies. Essential cookies (CSRF protection, language preference, this consent record) are always set — without them the site cannot function. Analytics cookies (Google Analytics, Baidu Tongji) only set after you opt in via the consent banner. Marketing cookies are reserved for future use and are not currently set.
For a per-cookie list and the ability to change your choice at any time, see Cookie information.

11. Changes to this policy
We may update this policy from time to time. The "last updated" date at the top of this page reflects the most recent revision. Material changes will be highlighted on the cookie consent banner so existing users are informed.
