Privacy Policy

What we collect

• Your tool inputs: nothing. All processing happens in your browser; inputs are never sent to a server.
• Analytics: Cloudflare Web Analytics — cookieless, IP-free, aggregate-only counts.
• Server logs: Nginx access logs kept 7 days, then deleted; used only for debugging.
• Browser storage: UI preferences — theme and pinyin visibility live in localStorage; after you allow cookies, the site stores two cookies: ck (your cookie-consent flag) and lang (your chosen interface language), both 1-year, used only to remember preferences — never for tracking, never personal data. Any future experience-improving storage also falls under this same "allow cookies" switch. Before you consent, zero cookies. After consent you can withdraw anytime via "Cookie settings" in the footer (deletes both cookies immediately; you can re-choose).
• Ads: Once AdSense is enabled, its cookies fall under Google's Consent Management Platform; EEA visitors see a consent choice.

What we don't do

No accounts, no form storage, no profiling, no data sale.

Third-party resources

The CSS framework is loaded from a public CDN (exposes visitor IP/User-Agent to the CDN provider); fonts and images are self-hosted.
