What the tools do not send
Birth dates, comparison dates, clock times, lunar inputs and calculated results are not included in our measurement requests or URLs. They are not stored by these tools. Leaving or reloading the page clears the tool’s own state, although your browser may independently restore form fields.
Anonymous measurement
We count page views, tool starts and successful calculations, plus impressions and clicks on our follow link. Events contain the tool identifier, a broad source category, device category, language, event time and a daily anonymous browser identifier. The browser identifier is stored locally, changes daily on Beijing time, and is hashed again on the server. Events do not contain a full referral URL, raw IP address or your inputs. Raw IP may be handled by the hosting provider for delivery; our event table does not store it. The existing daily process removes events older than 35 days.
Your choices
Measurement respects Do Not Track and Global Privacy Control when your browser enables either signal. Blocking measurement does not prevent calculation. Daily identifiers cannot reliably measure return visits across days. Test visits are excluded from business reports.
Other experiences and external sites
The separate I Ching and life-chart pages offer an optional deeper AI reading under the notice on those pages. These four utilities do not call that service. External links lead to sites with their own privacy rules. No advertising or GA4 script is installed on these tool pages at launch; any future integration will require an updated notice and applicable consent handling.
