Change note: from 2026-10-21, the former Terms of Service and Terms of Service (Mainland China edition) are merged into these single Terms of Service. For users outside Mainland China, the service operator is Praxis Global Limited (知行環球有限公司, Hong Kong); for users in Mainland China, the service operator is Nanjing Deep Practice Artificial Intelligence Technology Co., Ltd. (南京深度实践人工智能科技有限公司).
These Terms of Service govern access to and use of Praxis AI Cloud, account services, APIs, model routing, agent runtime, document processing, sandbox and browser tools, registry, billing, support, and related services. For users in Mainland China, these Terms are the user agreement between you and Nanjing Deep Practice Artificial Intelligence Technology Co., Ltd..
1. Operating entities and scope
For users outside Mainland China: the service operator is Praxis Global Limited (知行環球有限公司, Hong Kong). Nanjing Deep Practice Artificial Intelligence Technology Co., Ltd. may provide underlying technology, software development, IP licensing, deployment support, maintenance, and technical support.
For users in Mainland China: the service operator and personal information handler is Nanjing Deep Practice Artificial Intelligence Technology Co., Ltd. (南京深度实践人工智能科技有限公司).
"We" in these Terms means the operating entity that provides the service to you under the rule above. Sections that name no region apply to both groups of users; sections marked "for users in Mainland China" or "for users outside Mainland China" apply only to that group.
2. Eligibility and accounts
Users must have legal capacity to enter into these Terms. If a user uses the service for an organization, the user represents that they have authority to bind that organization. Users are responsible for account activity, credentials, API keys, workspace permissions, tenant configuration, and all use under their account.
3. Services
The service provides AI cloud, agent workspace, model routing, developer APIs, tool execution, document processing, registry, billing, and related platform capabilities. We may add, modify, suspend, or discontinue features. Beta, preview, experimental, or free features may be changed or withdrawn at any time and may be subject to additional limits.
4. Customer content and platform materials
Users retain ownership of their original content, including prompts, files, messages, code, data, configuration, and outputs to the extent permitted by law and third-party rights. Users grant us the rights needed to host, process, transmit, display, transform, secure, troubleshoot, and otherwise operate the service.
The platform, software, APIs, documentation, service design, operational data, routing metadata, diagnostics, aggregate analytics, and service-improvement outputs are owned or controlled by us, our affiliates, or licensors. No rights are granted except as expressly stated in these Terms.
5. User responsibilities
Users must comply with law, these Terms, the Acceptable Use Policy, applicable product documentation, and any plan limits. Users are responsible for the legality, accuracy, permissions, and rights in their content and instructions. Users must not misuse the service, interfere with security, overload systems, bypass limits, or use the service to harm others.
6. AI outputs
AI outputs may be inaccurate, incomplete, offensive, or unsuitable for a specific purpose. Users are responsible for reviewing outputs before relying on them, publishing them, using them in production, or making decisions that affect legal rights, safety, employment, credit, healthcare, housing, education, or other sensitive matters. The service is not a substitute for professional advice. Users are solely responsible for reviewing and verifying outputs before relying on, publishing, or acting on them.
7. Third-party services and model providers
The service may interoperate with third-party model providers, payment processors, hosting providers, identity providers, and tools. Third-party terms may apply. We are not responsible for third-party services outside our control, but will use reasonable efforts to disclose material subprocessors and provider roles; for users outside Mainland China, through the Praxis Trust Center.
8. Fees, billing, and suspension
Paid plans, usage-based charges, subscriptions, prepaid balances, enterprise fees, taxes, and refunds are governed by the applicable order, checkout terms, invoice, subscription terms, or refund terms. We may suspend or limit service for non-payment, security risk, abuse, legal risk, excessive usage, or breach of these Terms.
9. Disclaimers and limitation of liability
The service is provided on an "as is" and "as available" basis except where a separate written agreement states otherwise. To the maximum extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose, non-infringement, and uninterrupted or error-free operation.
To the maximum extent permitted by law, we will not be liable for indirect, incidental, special, consequential, or punitive damages, loss of profits, loss of revenue, loss of data, business interruption, or substitute services; for users outside Mainland China, this exclusion also covers exemplary damages. Unless a separate written agreement states otherwise, aggregate liability is limited, for users in Mainland China, to the fees you paid for the service in the three months before the event giving rise to liability, and, for users outside Mainland China, to the fees paid by the customer for the service in the three months before the event giving rise to liability.
10. Termination
Users may stop using the service at any time. We may suspend or terminate access for breach, legal risk, security risk, non-payment, abuse, or discontinuation of the service. Sections that by nature should survive termination will survive, including payment obligations, IP rights, disclaimers, liability limits, confidentiality, and dispute terms.
11. Governing law and disputes
For users in Mainland China: these Terms are governed by the laws of Mainland China (excluding conflict-of-laws rules). Disputes arising from these Terms are subject to the jurisdiction of the competent people's court at the domicile of Nanjing Deep Practice Artificial Intelligence Technology Co., Ltd. in Nanjing.
For users outside Mainland China: unless a separate written agreement states otherwise, these Terms are governed by the laws of Hong Kong, without regard to conflict-of-law rules. Courts in Hong Kong will have non-exclusive jurisdiction.
12. Indemnification
You will indemnify, defend, and hold harmless us, our affiliates, and licensors from and against any third-party claims, losses, liabilities, and reasonable expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your content, prompts, data, or instructions, including any claim that you submitted them for AI or other processing without the right or consent to do so; (b) your use of outputs in violation of these Terms or law; (c) prohibited or high-risk uses under the Acceptable Use Policy; (d) your failure to apply required human review before making decisions that have a material effect; and (e) your breach of these Terms or infringement of third-party rights.
13. Changes to the Terms
We may modify these Terms. For material changes, we will give advance notice by reasonable means, such as in-product notice or email. Continued use of the service after the effective date of a change constitutes acceptance. If you do not agree, you must stop using the service.
14. Assignment
We may assign these Terms, including in connection with a merger, acquisition, or reorganization. You may not assign these Terms without our consent.
15. Entire Agreement; Severability; No Waiver
These Terms, together with the policies and orders they reference, constitute the entire agreement between you and us regarding the service. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure or delay in exercising a right does not constitute a waiver of that right.
16. Force Majeure
Neither party is liable for any delay or failure to perform caused by events beyond its reasonable control, including natural disasters, war, network or power outages, upstream provider or infrastructure failures, and government actions.
17. Export Controls and Sanctions
You will comply with applicable export control, sanctions, and trade laws, and will not use or export the service in violation of them. You represent that you are not listed on any restricted-party list.
18. Feedback
If you provide feedback or suggestions about the service, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them without restriction and without obligation to you.
