Privacy

This site does not offer accounts or payments. It records a small first-party visit log so we can later tell whether anyone other than ourselves is reading the pages. The community page also accepts optional likes and comments.

Visit log

For ordinary browser visits, we store the time, path, a coarse referrer class (search, referral, direct, or internal), country (from Cloudflare), device class, and a hash used only to approximate unique visitors.

Likes and comments

If you leave a comment, we store the display name you typed (or leave it blank, in which case it shows as Anonymous / 匿名), the comment text, the time, and a hashed IP address used only for rate limiting and abuse control. We do not ask for an email address or a login. Likes are stored as a count tied to a random cookie plus that same hashed IP rate limit — one like per visitor per item. Comments may include links only if we allowed them; we currently reject comments that contain URLs, and we strip HTML. A “report” button can hide a comment after several reports. We do not seed fake comments or likes. Visits and comments made with the ?qa=1 query, the g4h_notrack=1 cookie, or our internal test header are excluded from public counts.

What is excluded

Add ?qa=1 once to set the opt-out cookie for this browser. There are no third-party advertising pixels on these pages.
