Privacy Policy
How we handle your data
All calculations on this platform — the Four Pillars chart, momentum curves, solar terms, five movements and six qi, and innate constitution — run entirely in your browser. The birth year, month, day and hour you enter are never uploaded to any server and never stored by us.
What we collect
- Birth information for chart calculations: used only in local memory and discarded when you close the page.
- Interface language preference: saved in your browser's local storage (localStorage) to remember Chinese / English.
- Payment information: if you purchase an AI deep analysis, payment is processed by a third-party payment provider; we do not store your card number or payment credentials.
We do not share with third parties
We do not sell, rent, or share any birth information with any third party. Apart from the local storage and payment provider mentioned above, no data leaves your device.
Your rights
You may delete locally stored data (such as language preference) at any time by clearing your browser storage. Since birth information never leaves your device, no separate deletion request is needed.
