Terms of use

By using this site you agree to the terms below. If you do not agree with any part of them, please stop using the site.

Last updated: 2026-10-07

1. The service

The self-service calculators, explanatory articles and printable result pages currently available on this site are free. The site does not collect payment or offer online checkout.

2. How you may use it

  • Do not use the site for unlawful purposes or to mislead others, or to impersonate a lawyer or legal service provider.
  • Do not scrape the site at scale or interfere with its normal operation.
  • You may quote results for personal reference, but not after removing the disclaimer, and not by claiming that the output is legal advice.

3. Intellectual property

Page structure, explanatory text, code and layout are protected by law. Statutory provisions themselves are public; we claim no rights over the law.

You may print or save result pages and reports for personal use. Bulk copying, resale or commercial republication is not permitted without permission.

4. Automated reports and fees

An automated report contains only the input snapshot, calculated results, working steps, statutory extracts and general caveats. It does not contain case-specific legal advice, and this version of the site does not charge for it.

If paid features are introduced later, the price, delivery method, refund terms and service provider will be published separately and shown before any payment.

5. Disclaimer and liability

The site is provided "as is" without express or implied warranty as to accuracy, completeness or fitness for a particular purpose. See the disclaimer page for the full limitation of liability.

6. Changes and governing law

We may update these terms as the service or the law changes, and will show a new date at the top of the page. These terms and any dispute arising from them are governed by the laws of the People’s Republic of China.
