Terms of Service

Last Updated: October 11, 2026

1. Introduction

Welcome to Paper Lantern, operated by Paper Lantern Labs LLC (“Paper Lantern,” “we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website and the services we provide (collectively, the “Services”). By accessing or using our Services, you agree to be bound by these Terms. If you do not agree to these Terms, please do not use our Services.

2. Use of Our Services

You must use our Services in compliance with all applicable laws and regulations. You agree not to misuse the Services, including but not limited to:

  • Engaging in any unlawful activity.
  • Interfering with the proper working of the Services.
  • Attempting to access data or accounts that do not belong to you.
  • Uploading or sharing content that is malicious, infringing, or harmful.

3. User Accounts

If our Services require you to create an account, you are responsible for maintaining the confidentiality of your account information and for all activities that occur under your account. You agree to notify us immediately of any unauthorized use of your account.

4. Intellectual Property

All content, features, and functionality of the Services, including but not limited to text, graphics, logos, and software, are the exclusive property of Paper Lantern and are protected by international copyright, trademark, and other intellectual property laws.

5. Termination

We may terminate or suspend your access to our Services at our sole discretion, without prior notice or liability, for any reason, including if you breach these Terms.

6. Disclaimers and Limitation of Liability

The Services are provided “as is” and “as available” without any warranties of any kind. We do not warrant that the Services will be error-free or uninterrupted. In no event will Paper Lantern be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or in connection with your use of the Services.

7. Inference API

This section applies to your use of the Paper Lantern Inference API (the “API”), provided by Paper Lantern Labs LLC.

API keys. You are responsible for all use of the API under your API keys. Keep them confidential and use commercially reasonable efforts to prevent unauthorized access. Notify us promptly if a key is compromised.

Your content and output. As between you and Paper Lantern, you own all right, title, and interest in the inputs you submit to the API (“Your Content”) and the outputs the API returns to you (“Output”). We use Your Content only to generate Output for you.

Zero Data Retention. Paper Lantern will not (i) log Your Content or Output, (ii) retain them beyond the time it takes to generate the Output and deliver it to you, or (iii) use them to train models. We log only request metadata (request ID, model, token counts, timing, and status), which contains no prompt or output content. We may preserve data where required by law.

Third-party models. Models served through the API are developed by third parties and may come with their own license terms. Your use of a model must comply with its license terms. In case of any conflict between these Terms and a model's license terms, the model's license terms govern.

Acceptable use. You will not use the API to:

  • Violate any law or infringe the rights of others.
  • Generate content that is unlawful, harmful, or deceptive.
  • Reverse engineer the API or circumvent its security or rate limits.
  • Introduce malicious code.
  • Resell access to the API without our written agreement.
  • Operate high-risk applications where a failure could lead to death, personal injury, or serious damage.

Fees. Prices are per token, in US dollars, as published by us or as agreed in writing. Unless otherwise agreed, invoices are due within 30 days. We may suspend the API for amounts more than 15 days overdue, after notice.

Accuracy of output. Output is generated by machine learning models and may be inaccurate, incomplete, or offensive. You are responsible for evaluating Output before relying on it. We do not warrant that results obtained from the API will be accurate or reliable.

Availability. We do not guarantee the API's uptime, quality, or performance unless agreed in writing. We may change or discontinue models with reasonable notice where practicable.

Suspension. We may suspend your access to the API, in whole or in part, if you breach these Terms, to prevent harm to the API or others, or where required by law. We will give notice where practicable.

Limitation of liability. To the maximum extent permitted by law, Paper Lantern's total liability arising out of or relating to the API is limited to the amounts you paid us for the API in the 12 months before the claim. We are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, or data.

Indemnification. You will defend and indemnify Paper Lantern against third-party claims arising from Your Content, your use of the API in breach of these Terms, or your violation of law.

8. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, USA, without regard to its conflict of law principles.

9. Changes to These Terms

We reserve the right to modify these Terms at any time. We will notify you of any changes by posting the new Terms on this page. Your continued use of the Services after any such changes constitutes your acceptance of the new Terms.
