Last updated: August 28, 2026. Welcome to the RainFlow TB Open Platform (“we”, “us”). By using our large-model API services (the web console and API endpoints, collectively the “Service”), you acknowledge that you have read, understood and agree to be bound by these Terms.
1. The Service
The Service provides API access to large language models under two billing modes: pay-as-you-go (wallet balance) and subscription (Coding Plans). We continuously improve the Service and may adjust features, model availability and plan benefits from time to time; material changes will be announced on the site.
2. Account and Registration
1. You must provide accurate registration information and keep your credentials (password, API keys, sessions) secure. You are responsible for all activity under your account.
2. Accounts are for personal use only and must not be sold, rented, shared or transferred to any third party.
3. If you suspect unauthorized access or a security issue, notify us immediately via the support channel.
3. Subscriptions, Billing and Refunds
1. Plan purchases, renewals and upgrades are charged from your wallet balance. Renewals append a new cycle after your current paid period; upgrades are prorated against the remaining time of the current cycle, and used quota is carried over to the new plan in proportion to the remaining time.
2. Plan quota includes the cycle quota plus 5-hour and weekly window limits. After the quota is exhausted you may choose to keep billing from your wallet balance (can be disabled in the console).
3. Top-up balance and purchased plans are virtual services. Once purchased, they are non-refundable and non-withdrawable, except where required by law.
4. Free Models
Free models carry a per-user daily quota. We may adjust the scope, quota and availability of free models based on operating costs, with notice on the site.
5. Acceptable Use
You agree not to use the Service to:
1. Share your account or plan quota with third parties, or resell the Service in any form;
2. Abuse free models with scripts or similar means, or otherwise disrupt the Service;
3. Generate or distribute content that violates applicable laws, or infringes others’ intellectual property or personal information rights;
4. Engage in any other conduct that violates laws, these Terms or public order and morals.
Violations may result in warnings, feature restrictions, suspension or termination of your account, without refund of fees already paid.
6. Intellectual Property
The software, interface, trademarks and documentation of the Service are owned by us. Rights in content generated through the Service are governed by applicable law; you are responsible for ensuring your inputs do not infringe third-party rights.
7. Availability and Disclaimers
1. The Service is provided “as is”. Model output is generated by AI and may be incorrect or incomplete; verify it before use. We are not liable for the accuracy or completeness of such output.
2. We are not liable for interruptions or changes caused by force majeure, network failures, upstream model provider adjustments or maintenance, but will endeavor to notify you in advance and restore service promptly.
8. Governing Law and Disputes
These Terms are governed by the laws of the People’s Republic of China. Disputes arising from these Terms should be resolved through friendly negotiation; failing that, either party may bring the dispute to the competent people’s court at the location of the Service operator.
9. Changes to These Terms
We may revise these Terms from time to time; material changes will be announced on the site. Continued use of the Service after changes constitutes acceptance of the revised Terms.
10. Contact Us
Questions about these Terms? Email [email protected] or reach us via the in-console “Feedback” feature.
Last updated: August 28, 2026. This policy is issued by the RainFlow TB Open Platform (“we”, “us”) in accordance with the Personal Information Protection Law of the People’s Republic of China, the Cybersecurity Law and the Data Security Law. It explains how we collect, use, store and protect your personal information when you use the Service (web console and API endpoints), and the rights you are entitled to by law.
1. Information We Collect
Following the principle of minimum necessity, we collect only what is required to provide the Service:
1. Account information: username, display name and password you provide at registration (stored only in irreversibly hashed form); when you sign in with a third-party account, we receive the user identifier and nickname returned by that platform.
2. Usage data: API call records (model used, token usage, fees, request time, IP address, User-Agent).
3. Transaction information: top-ups, plan purchases, order records and wallet transactions.
4. Content you submit: feedback you provide, and prompts and conversation content you send through the API.
2. How We Use the Information
1. To provide, maintain and improve the Service (authentication, billing and settlement, usage statistics);
2. For security and abuse prevention: detecting misuse and account theft to protect the Service and your account;
3. To comply with legal obligations, and to contact you when necessary (service notices, plan expiry reminders, announcements).
3. Sharing and Entrusted Processing
We do not sell your personal information. We share it only where necessary:
1. Upstream model providers: to fulfill the inference requests you initiate, we transmit the conversation content of that request to the relevant model provider, which does not include your direct identifiers such as account or password;
2. Payment and sign-in providers: the order information necessary to interact with the payment channel when topping up; the authorization flow with the corresponding platform when you sign in with a third-party account;
3. Disclosures required by laws, judicial authorities or administrative agencies.
4. Storage and Security
Your personal information is stored on the servers that run the Service; we do not provide it to parties outside mainland China. We protect it with encrypted storage, access controls and least-privilege authorization. We retain the information for as long as your account exists; after account deletion, we will delete or anonymize it within a reasonable period, except where the law requires otherwise.
5. Local Storage
We use localStorage in your browser to store login credentials, interface preferences and language settings, in order to keep you signed in and remember your settings. You can remove them at any time by clearing your browser data.
6. Your Rights
Under the Personal Information Protection Law, you have the right to access, copy and correct your personal information, to delete it and deactivate your account, and to withdraw consent. Send requests to [email protected] or via the in-console “Feedback” feature; we will respond within fifteen business days.
7. Protection of Minors
The Service is not directed to children under the age of fourteen. If you are under fourteen, please use the Service only with the accompaniment and consent of a guardian.
8. Policy Updates
We may revise this policy from time to time; material changes will be announced on the site. Continued use of the Service after an update constitutes acceptance of the revised policy.
9. Contact Us
