MiaoYan AI Keyboard — Terms of Service

Last updated: 14 October 2026
Effective: 14 October 2026

These Terms apply to the MiaoYan AI Keyboard app distributed on Google Play. The version distributed in mainland China is governed by its Chinese terms at /terms.html.

These Terms of Service ("Terms") are an agreement between you and Shenzhen Chainfun Technology Co., Ltd. ("we", "us") for the MiaoYan AI Keyboard software and related services (the "Service"). Please read them carefully, especially the parts in bold: the limitations of our liability, the nature of AI-generated content, and dispute resolution.

By downloading, installing, enabling or using the Service, you agree to these Terms. If you do not agree, please stop using and uninstall the Service.

1. Scope and Changes

• These Terms include this document and any rules we publish for the Service, which form part of these Terms.
• We may update these Terms when necessary and will notify you in the App or by updating the date above. Continuing to use the Service after an update means you accept the updated Terms.
• How we handle your personal information is described in our Privacy Policy, which has the same effect as these Terms.

2. The Service

• The Service is an AI-assisted keyboard for chatting. Features include AI reply suggestions, reply directions, text polishing, screen recognition, voice typing and ice-breaker suggestions.
• Available features depend on the version you use. We may add, change or remove features as the product evolves.

3. Your Account

• Some features require an account. You sign in with an email address you own and a one-time code; the information you provide must be true and accurate.
• Keep your email account and sign-in codes safe. You are responsible for losses caused by your own failure to protect them.
• You can delete your account in the App: Settings → App settings → Delete account. Deletion is permanent: your account data is deleted and cannot be recovered, and any purchased but unused benefits are forfeited. See the Privacy Policy for what is deleted and what is kept.
• You may not rent, lend, transfer or sell your account, or let anyone else use it.

4. Membership and Paid Services

• Some features are paid membership benefits. The plan, price, billing period and included benefits are those shown in the App or on the Google Play page at the time of purchase.
• Purchases made through Google Play are subject to Google Play's rules for payment, renewal and refunds; please request refunds through Google Play.
• If you turn on auto-renewal, you can turn it off at any time in Google Play's subscription settings. If you do not turn it off before the current period ends, it renews automatically under Google Play's rules.
• Membership benefits are for your personal use only and are not transferable. If the Service is suspended or terminated because you breached these Terms, fees paid are not refunded, except where the law requires otherwise.

5. Acceptable Use

You agree not to use the Service to:

• create, copy, publish or spread content prohibited by law, including content that is obscene, involves gambling, violence or terrorism, or incites crime;
• infringe anyone's reputation, privacy, intellectual property or other legal rights;
• commit fraud, harass, insult or attack others, or for any deceptive purpose;
• call the Service in bulk with scripts, bots, scrapers or other automated tools, or interfere with its normal operation;
• reverse engineer, decompile or disassemble the Service or try to obtain its source code;
• do anything else that breaks the law, public order or these Terms.

If you break these rules, we may warn you, restrict features, or suspend or terminate the Service, and we reserve the right to pursue legal liability.

6. AI-Generated Content (Important)

• AI features are provided by calling third-party large language model APIs. Results are probabilistic and uncertain, and may be inaccurate, incomplete, outdated or wrong.
• All AI-generated content is only a suggestion and is not professional advice of any kind (including legal, medical, financial or investment advice). Whether to use, edit or send it is entirely your decision, and you are responsible for the consequences.
• You must make sure your use of content generated through the Service does not infringe anyone's rights.
• You are responsible for disputes, losses or liabilities arising from your use or sending of AI-generated content.
• We make no express or implied warranty about the truthfulness, accuracy or completeness of AI-generated content.

7. Intellectual Property

• The software, trademarks, interface design, text, graphics and other elements of the Service belong to us or the respective rights holders. You may not copy, modify, distribute, display or otherwise use them without our written permission.
• Original content you enter belongs to you. You agree that we process it, within the scope of the Privacy Policy, as needed to provide the Service to you.

8. Changes, Interruptions and Termination

• We may suspend or terminate all or part of the Service for business, technical or maintenance reasons, and will make reasonable efforts to give advance notice.
• We are not responsible for interruptions caused by force majeure, network failures, interruptions of third-party services (including AI model APIs and email delivery) or government action.
• You may stop using and uninstall the Service at any time.

9. Disclaimer and Limitation of Liability

• The Service is provided "as is" and "as available". To the maximum extent permitted by law, we do not warrant that it is fit for a particular purpose, error-free or uninterrupted.
• To the maximum extent permitted by law, we are not liable for indirect losses, lost profits, lost data or loss of goodwill arising from your use of the Service, and our total liability will not exceed the amount you actually paid us for the Service in the twelve months before your claim.
• Nothing in this section excludes or limits any liability that cannot be excluded or limited by law, including your rights as a consumer under the law where you live.

10. Age Requirement (18+)

The Service is only for people aged 18 or over. By using the Service you confirm that you are at least 18 years old. If you are under 18, do not download or use the Service. If we learn that an account belongs to someone under 18, we will close it and delete its data.

11. Governing Law and Disputes

• These Terms are governed by the laws of the People's Republic of China (excluding Hong Kong, Macao and Taiwan), without regard to conflict-of-law rules, except where the law of the country you live in requires otherwise.
• We will try to resolve disputes amicably. If that fails, either party may bring the dispute before the People's Court of Nanshan District, Shenzhen, unless mandatory law gives you the right to sue in your home courts.
• If any part of these Terms is found invalid or unenforceable, the rest remains in effect.
