Terms of Service

Last updated: March 17, 2026

1. Agreement and Operator

These Terms of Service ("Terms") govern your access to and use of Teichat, including any website, application, chat interface, file-upload workflow, and related services we make available (collectively, the "Service"). By creating an account, accessing, or using the Service, you agree to these Terms.

Teichat is owned and operated by TeichAI. If you use the Service on behalf of a company or other entity, you represent that you have authority to bind that entity to these Terms.

2. Eligibility and Accounts

  • You must be at least 13 years old to use the Service
  • If you are under the age of majority where you live, you must have permission from a parent or legal guardian
  • You must provide accurate account information and keep it reasonably current
  • You are responsible for maintaining the confidentiality of your credentials and for activity under your account
  • We may enable, disable, or limit registration methods, including password sign-in and third-party sign-in, at any time

3. Service Description

Teichat provides an interface for interacting with one or more third-party AI models and optional tools such as web search and file upload. The Service may route your prompts, files, and related context to third-party providers selected by TeichAI or by your chosen model. Features, models, limits, and integrations may change over time.

The Service may also store conversation state associated with your chats, including uploaded attachments, tool-call records, and assistant timeline data such as reasoning or content blocks, so chats can be rendered, resumed, and managed within the product.

4. Acceptable Use

You may not use the Service to, or attempt to:

  • Violate any law, regulation, court order, or the rights of others
  • Generate, upload, or distribute unlawful, exploitative, fraudulent, defamatory, or infringing content
  • Develop or distribute malware, phishing content, credential-harvesting tools, or malicious code
  • Stalk, harass, threaten, abuse, dox, or invade another person's privacy
  • Attempt to gain unauthorized access to accounts, systems, models, prompts, secrets, or data belonging to others
  • Probe, disrupt, overload, scrape, reverse engineer, or interfere with the Service or its supporting infrastructure except as allowed by applicable law
  • Circumvent rate limits, safety controls, account restrictions, billing controls, or access restrictions
  • Use the Service to make solely automated decisions in high-risk contexts such as medical diagnosis, legal advice, credit, employment, housing, insurance, or public-sector determinations without qualified human review
  • Use the Service in a way that violates the policies or terms of third-party providers supporting the Service

5. User Content and License

You retain any rights you have in prompts, uploads, chat content, and other material you submit to the Service ("User Content"). You are responsible for ensuring that you have all rights, permissions, and legal bases needed to submit User Content and to instruct us to process it.

You grant us a non-exclusive, worldwide, royalty-free license to host, store, copy, transmit, display, adapt, and otherwise process User Content as necessary to operate, secure, maintain, and improve the Service for you, including by sending content to our hosting, storage, search, identity, and AI model providers. This license ends when the relevant User Content is deleted from the Service, except to the extent retention is required for backups, legal obligations, security, or dispute resolution.

If you enable the privacy setting that allows data collection for model training, new chats you create may be marked as eligible for training export. For chats marked that way, you also authorize us to include the chat and its stored conversation data in training-data exports for model training. Changing that setting affects only chats created after the change.

We may also apply separate downstream review or filtering processes to training exports in an effort to remove API keys, credentials, and other sensitive data before those exports are used for training. Those efforts are not a guarantee that all sensitive data will be detected or removed.

6. AI Features and Output

  • AI output may be incorrect, incomplete, biased, offensive, or unsuitable for your use case
  • You are responsible for reviewing and validating output before relying on it or sharing it with others
  • The Service is not a substitute for professional advice or qualified human judgment
  • Model availability, latency, output style, and provider policies may change without notice
  • Third-party providers may apply their own terms, usage policies, and retention practices to content processed through their services

7. Usage Limits and Access

We may impose token caps, weekly token quotas, rate limits, model restrictions, upload limits, or other fair-use controls. Those limits may vary by user, account type, or service settings and may be changed, suspended, or removed at any time.

8. Third-Party Services

The Service depends on third-party services, including AI model providers, search providers, identity providers, hosting services, and cloud storage providers. We are not responsible for outages, policy changes, data handling, or other acts or omissions of third parties. Your use of third-party services may also be subject to separate terms and privacy policies.

9. Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how personal information is collected, used, disclosed, and retained.

10. Suspension and Termination

We may suspend, restrict, or terminate your access to the Service, with or without notice, if we believe you violated these Terms, created risk or potential liability, interfered with the Service, or if we are required to do so by law or by a third-party provider. You may stop using the Service at any time.

11. Intellectual Property

The Service, excluding User Content and third-party materials, is owned by TeichAI or its licensors and is protected by intellectual property laws. Except as expressly allowed by these Terms or by applicable law, you may not copy, modify, distribute, sell, lease, sublicense, or create derivative works of the Service.

12. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, AND UNINTERRUPTED OR ERROR-FREE OPERATION.

13. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS.

TO THE FULLEST EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) USD $100.

14. Indemnity

To the extent permitted by law, you will defend, indemnify, and hold harmless TeichAI and its affiliates, personnel, and service providers from claims, liabilities, damages, losses, and expenses arising out of or related to your User Content, your use of the Service, or your violation of these Terms or applicable law.

15. Export and Sanctions Compliance

You may not use the Service in or for the benefit of any person or entity subject to applicable trade embargoes, sanctions, or export restrictions, and you may not use the Service in violation of export control laws.

16. Governing Law and Disputes

These Terms are governed by the laws of the jurisdiction in which TeichAI is established, excluding conflict of laws rules, unless a mandatory law requires otherwise. Unless TeichAI states otherwise in a separate written agreement, disputes will be resolved in the courts located where TeichAI is established, and each party consents to personal jurisdiction in those courts.

17. Changes to These Terms

We may update these Terms from time to time. The updated version will be posted here with a revised "Last updated" date. If a change is material, we may provide additional notice through the Service or by another reasonable method. By continuing to use the Service after the effective date of the updated Terms, you agree to the revised Terms.
