Terms of Use

1. What the service is

Kinh Dịch Online (kinhdichonline.com) lets you ask a question, cast a hexagram with a random algorithm on the server, and then receive a reading based on the classical I Ching text (the Judgment, the Image and the Line texts), written with the help of artificial intelligence (AI).

The service is cultural, for reference and reflection. We do not provide spiritual services, rituals or objects, and we do not promise any outcome in your life. See also the Disclaimer page.

2. Conditions of use

• You must be at least 18 years old. If you are under 18, please do not use the service.
• On first use, the system automatically creates a guest account for you, tied to the browser you are using. If you clear your browser data or change devices, you may lose access to that guest account.
• When Google sign-in is available, we recommend linking your account to keep your credits and history on every device.
• You are responsible for the content of the questions you submit and for keeping your device and account secure.

3. Free credits and paid credits

Each person gets a number of free short readings per day, with a limit per network address to prevent abuse. We may adjust or suspend free credits when needed to protect the system.

Paid credits are used to open the full reading. Credits do not expire, are tied to the account that bought them and cannot be transferred. Prices, payment methods and refunds are described on the Payment and Refund Policy page.

Paid packages only add depth of analysis. The free and paid versions are based on the same hexagram and the same classical text.

4. Prohibited conduct

• Using bots, scripts or automated tools to cast hexagrams, call the API or get past bot checks.
• Creating multiple accounts, changing network addresses or using other methods to obtain extra free credits.
• Deliberately trying to make the AI write unlawful or harmful content, or to bypass its safety rules (injecting instructions into a question).
• Submitting questions with unlawful, insulting or harassing content.
• Reselling, mass copying or commercially exploiting the site's content without written consent.
• Attacking, probing for vulnerabilities, overloading or interfering with the system without authorization.

When we detect a violation, we may temporarily block access, lock the account and keep logs as evidence. Unused credits on an account locked for fraud are not refunded.

5. AI-assisted content

Readings are written by AI based on the hexagram and the classical text, with a content filter. The AI may interpret inaccurately, and the ancient text can be understood in many ways. Please read a reading as a viewpoint to reflect on.

You are responsible for your own decisions. For health, legal, financial or psychological matters, please consult a qualified professional.

6. Intellectual property

The ancient I Ching text is a shared heritage. The interface, translations, presentation, source code, logo and images of the site belong to Kinh Dịch Online.

You may use your own reading for personal purposes, save it, print it and share its link. You may not use it to resell or to build a competing service.

7. Limitation of liability

To the extent permitted by law, we are not liable for any damage arising from your reliance on a reading to make decisions.

If a paid service fails because of us, our liability is limited to refunding the credit or the amount you paid for the part of the service that failed. This does not remove the consumer rights protected by Vietnamese law.

The service may be briefly interrupted for maintenance or because of incidents at our infrastructure providers. We will try to restore it quickly and will refund the credit if a paid reading fails.

8. Stopping use and deleting your account

• You can stop using the service at any time. Your account and purchased credits are kept, and credits do not expire.
• Guest accounts that have never bought credits and have not been used for 12 months are deleted automatically, together with their data.
• You can delete your account yourself on the Account page. Deletion cannot be undone. If you have unused credits bought within the last 7 days, the page warns you first and you can choose a refund of 50% of their value. All other credits are lost.
• On deletion, your questions, readings, history and Google link are deleted immediately. Orders and the credit ledger are kept without your identity, for the period required by accounting and tax law.
• Accounts locked for violations are disabled rather than deleted, so that evidence is preserved.

If Kinh Dịch Online shuts down, we will give at least 30 days' notice on the site and refund purchased credits that have not been used.

9. Changes to these terms

When the terms change, we update the effective date and the change history at the bottom of the page. Important changes concerning personal data will be announced on the site and we will ask for your consent again.

10. Governing law and disputes

These terms are governed by Vietnamese law. In case of a dispute, both sides will first try to negotiate through the channels on the Contact page. If negotiation fails, the dispute will be resolved by a competent court in Vietnam.
