Terms of Service

1. Acceptance of Terms

Welcome to Chivox MCP, a service provided by Suzhou Chivox Information Technology Co., Ltd. ("Chivox", "we", or "us"). By accessing, registering for, calling APIs, or using the SDKs, console, documentation, or related features, you confirm that you have read, understood, and agree to these Terms of Service. If you use the service on behalf of an organization, you represent that you are authorized to bind that organization to these terms.

2. Description of Service

Chivox MCP is an open speech assessment platform that provides speech evaluation capabilities to developers through the Model Context Protocol (MCP), APIs, SDKs, documentation, and management tools, including pronunciation scoring, diagnosis, and result delivery for words, sentences, passages, dialogues, and other supported task types. Specific service scope, concurrency, usage, fees, support, and data processing arrangements are governed by the applicable order, agreement, data processing agreement, or product documentation.

Chivox acts as a neutral technology service provider and provides speech assessment capabilities under the applicable agreements. You are responsible for the products, content, business workflows, user relationships, qualifications, licenses, and end services that you develop, operate, publish, or provide using the service.

3. Order of Precedence

If these terms conflict with a separately executed agreement, order form, data processing agreement, or addendum between you and Chivox, the executed document will control for the conflicting subject matter. Matters not covered by an executed document remain governed by these terms.

4. Service Rules and Notices

Product descriptions, technical documentation, API documentation, integration specifications, pricing rules, package descriptions, service level commitments if any, security requirements, console prompts, platform announcements, and orders or addenda confirmed by the parties form part of these terms. We may send service notices through website announcements, console notices, email, SMS, instant messaging tools, or other contact details you provide. Notices are deemed reasonably delivered when sent to your reserved contact information or published on the platform.

5. Account and Security

You may need an account or API Key to use the service. You agree to:

• Provide accurate and complete registration information;
• Protect your account, password, API Keys, tokens, and other credentials;
• Configure permissions based on roles and the principle of least privilege, and promptly revoke access for departed, transferred, or outsourced personnel;
• Notify us immediately of any unauthorized account use.

6. API Usage Policy

When using our API, you agree to:

• Use the API only for lawful purposes;
• Not upload, process, or distribute unlawful, infringing, fraudulent, harmful, obscene, violent, gambling-related, politically prohibited, or otherwise improper content;
• Not bypass authentication, rate limits, billing, concurrency, or security controls, or attack, scan, stress test, interfere with, or disrupt the service;
• Not share, sell, lease, transfer, or sublicense API Keys to unauthorized third parties;
• Comply with request limits, concurrency limits, package usage, technical documentation, and service rules;
• Coordinate capacity with Chivox in advance of large events, concentrated traffic, or expected concurrency spikes.

7. Fees, Packages, and Trials

If the service is paid, you must pay fees according to the applicable order, package, console price, or billing rules confirmed by the parties. You are responsible for service restriction, suspension, data deletion, or business interruption caused by overdue payment, package depletion, concurrency overuse, payment failure, or failure to renew. We may provide free trials, beta tests, preview features, or experience quotas, which usually have time, quota, feature, and stability limits. Unless expressly committed in writing, such services are not subject to the availability or service level commitments of commercial services.

8. Customer Content and Data Responsibility

You retain the rights you lawfully hold in text, audio, metadata, and business data submitted through the service. You are responsible for obtaining all required authorization, consent, or legal basis for uploading, processing, delegated processing, and cross-system transfer of such data, especially where personal information, sensitive personal information, minors' information, examination data, or education-related data is involved. You are responsible for content, configurations, or usage that violates law, infringes third-party rights, or breaches these terms.

For business data submitted, generated, processed, or stored by you and your end users through the service, you are usually the controller or personal information processor of that data, and Chivox usually processes it as an entrusted technology service provider according to your instructions and the applicable agreements. Any separate data processing agreement or written arrangement controls.

9. Intellectual Property

The algorithms, models, APIs, SDKs, documentation, interface designs, trademarks, logos, and related technology in the service are owned by Chivox or its licensors. Without Chivox's written permission, you may not copy, modify, reverse engineer, decompile, disassemble, sell, transfer, sublicense, distribute, or create derivative works from the service. Your own applications and lawful content remain yours, but you do not acquire rights in Chivox's underlying technology, models, or service.

The service may include or rely on third-party software, open-source components, cloud infrastructure, or external services. Such third-party content may be subject to its own licenses, service terms, or open-source agreements, and you must comply with applicable third-party rules. Except as required by law or expressly committed by us, Chivox is not responsible for third-party service availability or third-party content beyond these terms.

10. Availability and Disclaimer

Chivox will use reasonable technical and administrative measures to maintain service stability, but internet services may be affected by networks, equipment, third-party services, capacity, maintenance, attacks, regulatory action, force majeure, and other factors. We may temporarily interrupt or restrict the service for maintenance, upgrades, troubleshooting, or security risk control, and will provide advance or timely notice where reasonably practicable. To the maximum extent permitted by law, Chivox does not warrant that the service will be uninterrupted, error-free, fit for a particular commercial purpose, or suitable for a specific scenario beyond express commitments.

11. Changes, Suspension, and Termination

We may adjust service content, interfaces, documentation, usage limits, billing rules, or technical solutions for product, security, compliance, operational, or business reasons, with notice through platform announcements, in-product notices, email, or other reasonable methods. If you violate these terms, executed documents, law, or security requirements, or if you fail to pay fees, exceed usage, abuse API Keys, attack the service, or harm third-party rights, Chivox may restrict, suspend, or terminate the service and reserve all available remedies. To avoid or reduce security incidents, violations, service attacks, or material risks, Chivox may first take necessary measures and notify you within a reasonable period.

After service termination, you must immediately stop using the relevant APIs, SDKs, documentation, and credentials, and complete data export, deletion, or return according to the parties' arrangements. Information required by law or necessary for settlement, audit, or dispute resolution may be retained for the necessary period, but will not be used for unrelated business purposes.

12. Confidentiality

Each party must protect non-public technical, commercial, account, interface, pricing, data, documentation, and other confidential information learned through the service. Confidential information may not be disclosed to third parties without the disclosing party's written consent, except where required by law, regulators, courts, or as necessary to provide or receive the service.

13. Updates to Terms

We may update these terms due to changes in laws, product adjustments, or operational needs. For updates that materially affect your rights or obligations, we will provide notice through reasonable methods. If you continue using the service after an update takes effect, you are deemed to accept the updated terms. If you do not agree, you should stop using the affected service and handle purchased services and data according to the parties' arrangements.

14. Governing Law

These terms are governed by the laws of the People's Republic of China. Disputes shall first be resolved through negotiation; if unsuccessful, they shall be submitted to a court of competent jurisdiction in Suzhou.
