About Lumina
A traditional calendar, approached with clarity.
Lumina is a quiet BaZi tool for people who want to inspect the calculation, reflect at their own pace, and keep their own judgment.
Show the working
The chart, place record, time convention, and calculation version stay visible. Interpretation cannot silently rewrite a calculated result.
Leave unknowns unknown
When an exact birth time is unavailable, Lumina does not invent one. It shows only the correlated facts the input can support.
Protect human agency
Reflections are optional prompts for entertainment and self-inquiry—not diagnoses, predictions, or instructions for important decisions.
Where the product stands
Lumina is in a private prelaunch preview. The free chart works locally in the browser. Account persistence, customer Checkout, production support, and public mobile-store releases remain closed until their evidence and operating safeguards are complete.
Built as a product, not an oracle
The interface stays restrained so the chart can be read without spectacle. Cultural context, privacy boundaries, accessible reports, recovery paths, and tested failure states are treated as part of the product—not footnotes added later.
