Fangyi

User Agreement

Effective October 22, 2026 Also published in Chinese. For users of the app in English, this English version applies.

Thank you for using Fangyi (Android package app.linquan.fangyi, “the app”). The app is run by an independent developer (“we”, “us”). By downloading, installing or using the app, you agree to this agreement. If you do not agree, please do not use the app.

1. What the content is: not a medical service

All of the app’s content, including the constitution self-check result, the marks on ingredients and recipes, the local qi reading, the Lore column and the double-hour quotations, is a collection of, and reference to, traditional Chinese wellbeing culture. It is offered only for cultural interest and as general lifestyle reference:

• the app does not give medical advice, and its content is not diagnosis, treatment or guidance on medication;
• the result of the constitution self-check is a rough grouping based on a questionnaire, not the finding of a medical examination;
• if you have any health concern or feel unwell, consult a licensed physician or your local health service, and do not use the app’s content in place of medical care;
• some of the marks on ingredients are compiled with the help of large language models, and the pieces in Lore are drafted with the help of AI (see below).

2. Content compiled with AI

Some of the marks on ingredients are compiled with the help of large language models: several models label them independently and cross-check one another, and where they differ, a person decides. The pieces in Lore are drafted with the help of AI, and we review each one before it is published. This content may still contain errors, omissions or departures from the classical texts. It is offered for reference only, and should not be taken as a promise of any fact, effect or outcome.

3. Trial and one-time purchase

The app is free to download, with no ads. Your trial begins when you finish the first-launch introduction and runs until the second new solar term after that: about fifteen to thirty-one days, always including one whole solar term. During the trial, every feature is available.

After the trial, this period’s foods (the ingredients and recipes suited to this period, and the “suited” and “best suited” marks for this period in the ingredients and recipes library) need a one-time purchase of the Complete Edition to keep using. The Complete Edition is paid for once; you will not be charged again automatically. Purchases, payment and refunds are all handled by Google Play under its policies.

The Complete Edition gives access to the content described above. It is not a promise about how often the app will be updated or what form its content will take. We reserve the right to change how the service works; if we do, we will announce it in the app in advance.

4. Fair use

You agree not to:

• call the app’s back-end interfaces in bulk by automated means (scripts, crawlers and the like);
• reverse-engineer, interfere with or get around the app’s rate limits and authentication;
• use the app’s content for unlawful purposes, or republish it on a large scale without giving its source.

To keep the service available to everyone, the back-end interfaces have usage limits; abuse may lead to the service being restricted for the device concerned.

5. Intellectual property

The app’s interface design, written content and program code belong to us or to the respective rights holders. Classical texts quoted in the app are in the public domain, with their sources given alongside. Credits for third-party data sources (such as climate reanalysis data) are on the “Basis and sources” page in the app.

6. Availability

The app is a project maintained by one person. We do our best to keep the service running, but make no warranty, express or implied, of availability, continuity or accuracy of content. The service may be interrupted by maintenance, faults or events beyond our control; major maintenance will be announced in the app.

7. Limitation of liability

To the fullest extent permitted by applicable law, we are not liable for any indirect, incidental or consequential loss arising from the use of, or inability to use, the app. Decisions about your health, diet or other aspects of your life made in reliance on the app’s content are your own responsibility; please be sure to read section 1.

8. Termination

You may stop using the app and uninstall it at any time. If you seriously breach this agreement (for example, by any of the conduct listed in section 4), we may restrict or stop providing the service to the device concerned.

9. Changes to this agreement

If this agreement changes in substance, we will announce it in the app and update the effective date on this page. Continuing to use the app after a change means you accept the revised agreement.

10. Governing law

This agreement is governed by the laws of the Province of Ontario, Canada, excluding its conflict-of-laws rules.
