Privacy
The birth-date and compatibility tools work without an account. This page explains local calculations, ordinary hosting data, and optional third-party services.
Birth-date tools
Birth dates entered in the Chinese zodiac calculator are processed by JavaScript in your browser. The form does not submit the date to our server, create a profile, or store a birth-date history. Compatibility selections are also calculated locally.
Hosting and technical logs
The site may be delivered through Cloudflare. Like most hosting providers, Cloudflare may process IP addresses, request timestamps, user-agent information, security signals, and requested URLs to deliver pages, prevent abuse, and maintain service reliability.
Optional analytics
The production configuration can enable Google Tag Manager, Umami, Microsoft Clarity, or OpenPanel. A service is included only when its environment variables are configured. These providers may use cookies or similar technologies according to their own policies.
Optional advertising
Google AdSense can be enabled in production. When enabled, Google and its partners may process device and browsing data to select, deliver, measure, and protect advertising. Consent controls should be configured where required by applicable law before personalized advertising is enabled.
External links and changes
Links to calendar, museum, and cultural references lead to third-party websites with their own privacy practices. This notice may be updated when hosting, analytics, advertising, or legal requirements change. The effective date above identifies the current version.
