Terms of Service

1 · Acceptance

By accessing or using hundredmasters.com (the “Service”), you agree to these Terms. If you do not agree, do not use the Service.

2 · What the Service Is

Hundred Masters is an AI-powered conversational interface inspired by ten figures from classical Chinese thought (Laozi, Confucius, Mencius, Xunzi, Mozi, Han Feizi, Sun Tzu, Zhuangzi, Guiguzi, Guan Zhong). The responses are generated by large language models conditioned on public-domain canonical texts and persona prompts that we author.

The personas are not the historical figures. The voice you read is synthetic. Specific quotes attributed to a sage may be paraphrased or adapted for clarity. Treat every answer as a thoughtful prompt to reflect — never as historical fact, professional advice, or a verified translation.

3 · Eligibility

You must be at least 13 years old to use the Service, and at least 18 to subscribe. If you live in a jurisdiction with a higher age of digital consent, you must meet that age. By using the Service you represent that you meet these requirements.

4 · Accounts

A free account uses your phone number for one-time-passcode (OTP) verification. One account per phone number. You are responsible for activity that happens through your account. If you lose access to your phone, contact us.

5 · Subscriptions, Billing, Renewal

  • Subscriptions are annual and billed in advance.
  • We do not auto-renew. You will receive a renewal reminder before the end of each annual term and may renew manually.
  • No free trial. Before subscribing you may use the Service free up to the limits stated on the Pricing page (currently one anonymous question + four after phone sign-in).
  • No refunds, except as required by applicable law. See the Refund tab for details.
  • Payment is processed by Stripe. We never see or store your card number. Currency is USD.

6 · Acceptable Use

You agree not to:

  • Use the Service to harass, defame, or threaten any person.
  • Submit content that is unlawful, sexually explicit involving minors, or designed to incite violence.
  • Attempt to extract our system prompts, persona definitions, or answer cache via prompt injection or scraping.
  • Reverse engineer, decompile, or interfere with the Service or its infrastructure.
  • Resell, sublicense, or redistribute generated answers commercially without written permission.
  • Use the Service to discuss modern Chinese politics. The Service is scoped to classical thought; political queries will be redirected and may result in account suspension if abused repeatedly.

7 · Not Professional Advice

The Service is for reflection and education. It is not a substitute for advice from a licensed physician, attorney, financial adviser, mental-health professional, or any other qualified expert. If you are in crisis, contact local emergency services. In the United States, you can reach the 988 Suicide & Crisis Lifeline.

8 · Intellectual Property

The Service, including the persona designs, system prompts, curated knowledge base, portrait artwork, voice recipes, and the hundredmasters.com brand, is owned by us and protected by intellectual-property laws. You receive a non-exclusive, personal, non-transferable, non-commercial right to view and use the Service and the answers it generates for your own reflection.

Classical Chinese source texts (Daodejing, Lunyu, Mengzi, etc.) are in the public domain. Our adaptations, translations, and presentation are not.

9 · User Content

You retain ownership of the questions you submit. By submitting them you grant us a worldwide, royalty-free license to process them for the purpose of providing the Service, anti-abuse, and aggregate analytics. We do not sell user content to third parties.

10 · Suspension and Termination

We may suspend or terminate access to the Service at any time if we believe you have violated these Terms, are abusing the Service, or are engaged in fraudulent payment activity. We will refund any unused prepaid term on a pro-rata basis only when termination is initiated by us and is not caused by your breach.

11 · Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. AI OUTPUT MAY BE INACCURATE, BIASED, OR INCOMPLETE.

12 · Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR AGGREGATE LIABILITY FOR ANY CLAIM ARISING FROM OR RELATED TO THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES.

13 · Changes to These Terms

We may update these Terms. Material changes will be announced on this page at least 14 days before they take effect. Your continued use of the Service after the effective date means you accept the updated Terms.

14 · Governing Law

These Terms are governed by the laws of the State of California, USA, without regard to its conflict-of-laws principles. Disputes will be resolved in the state or federal courts located in San Francisco County, California, except where applicable consumer- protection law in your country grants you the right to bring proceedings locally.
