Terms of Service

Welcome to LLM-notebook (the “Service”). The Service is operated by Shanghai IntLinkBridge Technology Co., Ltd. (上海智连桥科技有限公司, “we”, “us”). Please read these Terms of Service (the “Terms”) carefully before creating an account or using the Service. By creating an account, accessing, or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms.

1. About the Service

The Service is an AI-native notebook: it lets you collect LLM conversations, web pages, PDFs/Office documents and images into a single material library, ask questions grounded in that material with cited sources, and have a built-in Agent read and write your notes.

We may adjust, add, or remove features within reason. If a change affects paid features or materially affects your rights, we will notify you in advance under Section 12.

2. Accounts and Eligibility

You need an account to use the main features of the Service. You agree to provide a genuine, accurate email address and to keep it up to date.

• You must be at least 18 years old, or use the Service with the consent of a legal guardian.
• You are responsible for safeguarding your account credentials (password or third-party sign-in) and for all activity under your account.
• Accounts are for your own use and may not be transferred, lent, or shared. If you believe your account has been compromised, contact us immediately under Section 14.

3. Subscriptions, Billing, and Credits

The Service offers a free trial period and paid subscriptions. The trial starts on the date you register, and a welcome credit is granted upon registration.

• Subscriptions come in monthly, quarterly, and annual tiers. The tiers, prices, and entitlements in effect at the time of purchase are those displayed on our pricing page.
• Purchases are made manually. We do not auto-charge and do not auto-renew. When a subscription expires, you purchase again if you want to keep using paid features — there is nothing you need to cancel.
• A paid subscription includes a credit grant each billing cycle. You may also top up credits separately; topped-up credits are not tied to the subscription cycle.
• Credits are consumed according to the actual cost of the AI model calls you incur, denominated in Chinese yuan cents. Credits have no cash value and may not be transferred, withdrawn, or exchanged.
• When a subscription expires or credits run out, paid capabilities (such as Agent runs and background parsing jobs) are paused. Your stored material remains viewable, and we will not delete your data for this reason.

4. Refunds

Subscriptions are non-refundable once purchased. If you no longer wish to use paid features, simply stop purchasing — the Service does not auto-renew, so there is nothing to cancel.

Topped-up credits are likewise non-refundable. If the Service has been unavailable for an extended period due to our fault, or if you are charged twice or billed incorrectly, please contact us so we can investigate.

5. Your Content

Material, notes, and conversations that you upload, import, or create in the Service (“Your Content”) belong to you. We do not acquire copyright in Your Content by providing the Service.

To provide the Service, you grant us permission to store, process, and transmit Your Content to the extent necessary — for example, to parse documents, generate summaries, call AI models, or export data at your request. This permission is limited to operating the Service and ends when you delete the relevant content or close your account.

You are responsible for the legality of Your Content and its sources. You agree not to upload or process anything that infringes the copyright, trade secrets, privacy, or other lawful rights of others, or that applicable law prohibits.

6. AI-Generated Content

The Service includes features powered by third-party large language models. AI-generated content may be inaccurate, incomplete, or biased. It is provided as an aid for reference only and does not constitute legal, medical, financial, investment, or other professional advice.

Please verify AI-generated content independently before relying on it for any important decision. You are responsible for the AI-generated content you adopt, publish, or rely on.

7. Acceptable Use

You agree not to use the Service to:

• violate any applicable law or regulation, or infringe the lawful rights of others;
• upload or distribute malware or spam, or engage in fraud or phishing;
• mass-register accounts by automated means, abuse credit grants, or circumvent quota or billing limits;
• reverse engineer, scrape, or stress-test the Service, or attempt to gain unauthorized access to data or systems;
• use the Service’s capabilities in a way that breaches a third party’s terms (for example, circumventing a model provider’s usage restrictions).

If you engage in any of the above, we may restrict features, suspend, or terminate your account depending on severity.

8. Intellectual Property

The Service’s software, interface, icons, trademarks, name, built-in templates and themes, and all documentation we provide are owned by us or our licensors.

Provided you comply with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable license to use the Service normally. Beyond that, you may not copy, modify, distribute, sell, or commercially exploit the above without our written permission.

9. Availability and Changes

We make reasonable efforts to keep the Service available, but we do not promise it will be uninterrupted or error-free. The Service may be temporarily unavailable due to maintenance, upgrades, third-party dependency failures, network attacks, or events beyond our control.

We may adjust the Service’s content, storage allowance, or usage limits where necessary. If a change materially reduces entitlements you have already paid for, we will offer a comparable alternative or compensation.

10. Termination

• You may stop using the Service at any time and may delete content or request account closure from your account page.
• If you materially breach these Terms, we may suspend or terminate your access to the Service.
• After termination, we retain data for as long as the law requires and delete the rest in accordance with our Privacy Policy. Paid subscription fees are handled under Section 4.

11. Disclaimer and Limitation of Liability

To the maximum extent permitted by law, the Service is provided on an “as is” and “as available” basis. We are not liable for losses arising from: your own actions, device, or network; failures of third-party services (including AI model providers, payment processors, and cloud providers); or interruptions caused by events beyond our control.

To the maximum extent permitted by law, our total liability under these Terms is capped at the total amount you actually paid us in the 12 months preceding the event giving rise to the claim. We are not liable for indirect losses, lost profits, lost data, or loss of goodwill.

Nothing in this section excludes or limits liability that cannot lawfully be excluded or limited.

12. Changes to These Terms

We may revise these Terms from time to time. When we do, we will update the “Last updated” date on this page. For changes that materially affect your rights, we will notify you in advance via an in-product notice or email.

If you continue to use the Service after a revision takes effect, you are deemed to accept the revised Terms. If you do not accept them, please stop using the Service and you may request account closure.

13. Governing Law and Disputes

These Terms, including their formation, validity, interpretation, performance, and any dispute arising out of them, are governed by the laws of the People’s Republic of China, excluding its conflict-of-law rules.

Any dispute arising out of these Terms or the Service shall first be resolved through friendly negotiation. If negotiation fails, either party may bring proceedings before the Qingpu District People’s Court of Shanghai.
