Privacy Policy
The short version: your BaZi birth details are calculated locally and are not uploaded for the calculation.
Last updated: September 19, 2026
Birth details stay in your browser
The BaZi calculator processes the birth date, time, gender, and selected city locally in your browser. We do not require an account, and the calculator does not send those birth details to our server or save them in a database.
Technical data
Like most websites, our hosting provider may process standard request data such as an IP address, browser type, requested URL, and timestamp for security, reliability, and delivery. If privacy-friendly analytics are enabled, we may receive aggregate usage information that does not include the birth details entered in the calculator.
City search and map picker
Typed city matching uses a city and timezone dataset delivered with the website and runs in your browser. If you open the optional map picker, map tiles are requested from Esri. When you confirm a point, its coordinates are sent directly from your browser to OpenStreetMap's Nominatim service to obtain a readable place name. The selected coordinates are still used locally for the BaZi calculation and are not saved by our server.
Cookies and local storage
We may use essential browser storage for basic site preferences and technical operation. The calculator does not intentionally store your completed chart or birth details. You can clear site data at any time through your browser settings.
Third-party links
Our guides may link to external resources. Those websites operate under their own privacy policies, and we are not responsible for their content or data practices.
Changes
We may update this notice as the site evolves. If a future feature changes how personal information is handled, this page will be revised before that feature is made available.
