Privacy Policy

The short version: this site has no accounts, no logins, and no mailing list. The only data it handles is standard website analytics.

What we collect. We use Google Analytics to understand which pages are read and where visitors come from. It sets cookies and records standard usage data (pages visited, approximate location, device type) in aggregate. Google's handling of that data is described in Google's own privacy policy. You can block analytics cookies in your browser settings and every page keeps working.

What we never collect. The luck checker on this site runs entirely in your browser. Your birth year is used on your device to compute the result and is not sent to us, stored by us, or shared with anyone. There is nothing to delete because nothing is kept.

No accounts, no email. This site offers no signup and keeps no mailing list. If you write to the contact address in the footer, we use your email to reply and for nothing else.

Third parties. Google Analytics is the only third-party service on this site. We do not sell, share, or trade any visitor data.

The companion app. If a page links to the zhiji app, the app is a separate service with its own terms and privacy policy, which are presented to you there.

Changes. If this policy changes, the change is dated here.
