The four pillars, the ten gods, luck cycles, the twelve ZiWei palaces and their transformations, the nine QiMen palaces and patterns, and the almanac's do-and-avoid and spirits are all computed by a local chart engine. We do not hand-write, remember or guess any stem or branch. Every section shows the engine's raw output so you can check it yourself.

The written reading is AI-authored, but it may cite only stems and branches the engine already produced. The program collects every pair in the chart; any pair absent from it is a violation. After one corrective retry it still fails, you get the chart with no reading at all. No reading is better than a plausible wrong chart.

The 时辰 follows local clock or true solar time at the birthplace. "Now" is read in Malaysia time (UTC+8), not the server's UTC. Before 1982 Malaysia used +07:30, and if your birth sits near a two-hour boundary we will tell you to verify the recorded time.

The chart is free and complete — not weakened to sell the reading. What is paid is the written interpretation and the per-use question service, because those cost real model usage every time. All prices come from a server-side catalogue the client cannot alter.

A chart shows structure and tendency, not an unchangeable command. This does not predict specific events and is not a substitute for medical, legal or financial advice. Zodiac-style content grades the day's structure by traditional relations: a lens, not a verdict.

Birth details are used only to cast charts — nothing else, and never sold. Readings are cached by content hash, so the same chart never calls the model twice and is never billed twice.
