Terms of use

Welcome to Yuen Chi Lab. By using this site and service you agree to these terms. If this English version differs from the Chinese version, the Chinese version prevails.

1. The service

Yuen Chi Lab provides Qimen Dunjia and Zi Wei Dou Shu charting tools, a dictionary, and readings compiled from classical rules (“Yuen Chi Readings”).

2. For reference only

Readings are traditional-culture reference material. They are not a guarantee or a prediction, and they do not replace medical, legal, financial, investment or other professional advice. For questions about health, lawsuits or investments, consult a qualified professional. You are responsible for your own decisions.

3. Accounts

You must give a valid email address and keep your sign-in method secure. Each person should use one account; we may remove credits or accounts obtained through fake or multiple accounts.

4. Public beta and payment

The service is free during the public beta. We will announce the end date and prices one month before it ends, and nothing will be charged automatically. Credits collected during the beta never expire. Refunds are covered by our refund policy.

5. Intellectual property

The software, text, reading content and design of this site and service belong to Yuen Chi Lab. The classical texts themselves are in the public domain. Do not copy, resell or bulk-extract the service's content by automated means without our permission.

6. Limitation of liability

To the extent the law allows, Yuen Chi Lab is not liable for any loss arising from your use of, or reliance on, any reading.

7. Changes to these terms

We may change these terms from time to time; continuing to use the service means you accept the changed terms.

8. Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region.
