- No accounts, no comment section, no forms.
- Visits are counted with Cloudflare Web Analytics, which sets no cookies and does not identify you; it counts page views, referrers and country or region. Simplified-Chinese pages also carry Baidu Tongji, which does set cookies for counting visits and referrers; other language versions do not.
- Videos on chapter pages are embedded in YouTube's privacy-enhanced mode (youtube-nocookie.com); once you press play, YouTube handles data under its own privacy policy.
- Fonts load from Google Fonts, so your browser requests font files from Google.
- Your language choice and whether you dismissed the “add to home screen” tip are kept in your browser's local storage; pages you have read are cached on your device for offline use. None of this is uploaded.
- If you write to us with a correction or question, the email is used only to check and reply. If your correction is listed on the corrections page, we show only the username you give us, never your address; write to us and we will remove it.
- If anything here changes, we will update this page and the date below.
