Terms of Service

1. Agreement to Terms

These Terms of Service (“Terms”) form a binding agreement between you and Langkast and govern your access to and use of Langkast. By creating an account or using the service, you agree to these Terms. If you are using Langkaston behalf of an organization, you represent that you have authority to bind that organization, and “you” refers to that organization.

If you do not agree to these Terms, do not use Langkast.

2. Description of Service

Langkast is a team AI workspace that gives every member of your organization on-demand access to multiple frontier AI models, agents, and shared company knowledge through a single subscription. We may add, modify, or discontinue features over time. Where a change materially reduces core functionality, we will give reasonable advance notice.

3. Accounts & Eligibility

You must provide accurate information when creating an account and are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your account. Notify us promptly at the address in section 19 if you suspect unauthorized access. You must be at least 18 years old, or the age of legal majority in your jurisdiction, to use Langkast.

4. Organization Accounts & Administrators

If you join an organization’s workspace, an administrator may access, manage, restrict, transfer, or delete your account and its content, and may control the settings that apply to your use of the service. Your organization is responsible for its members’ use of Langkast and for ensuring it has any consents required to process the content its members submit.

5. Free Trial & Billing

New organizations receive a free trial with no credit card required at signup. Paid subscription plans and billing are a forthcoming addition to Langkast; when introduced, we will provide clear pricing and obtain your consent before any charge is made. Unless stated otherwise, fees will be exclusive of taxes, and you will be responsible for applicable taxes.

6. Acceptable Use

You agree not to:

• Use Langkast for any illegal, harmful, deceptive, or abusive purpose, including generating content that violates applicable law or infringes the rights of others.
• Resell, sublicense, or provide Langkast or access to the underlying AI models to third parties outside your organization without our written consent.
• Attempt to circumvent usage limits, rate limits, or security controls, or violate the acceptable use policies of the underlying AI model providers.
• Reverse engineer, decompile, or attempt to derive the source code or underlying models of the service, except to the extent this restriction is prohibited by law.
• Use the service or its outputs to build or train a competing AI model or product.
• Interfere with or disrupt the integrity or performance of Langkast or its underlying infrastructure, or access it by automated means other than an interface we provide.

7. Your Content & Ownership

You retain all ownership rights to the content you submit to Langkast, including prompts, files, and other materials (“Your Content”). You grant us a limited, non-exclusive, worldwide license to host, process, and transmit Your Content solely to provide, secure, and support the service. This license ends when you delete Your Content, except for copies retained in routine backups.

You represent that you have the necessary rights to submit Your Content and that doing so does not violate any law or third-party right. We do not use Your Content to train AI models.

8. AI Outputs

Langkast generates responses using third-party AI models. As between you and us, you own the outputs generated from your inputs, to the extent ownership is available under applicable law. Because of the nature of machine learning, outputs may not be unique, and other users may receive similar responses.

Outputs may be inaccurate, incomplete, or inappropriate for your use case and do not constitute professional, legal, medical, or financial advice. You are responsible for evaluating and verifying any output before relying on it, and for any decision you make based on it.

9. Our Intellectual Property

Langkast, including its software, interfaces, documentation, and trademarks, is owned by us and protected by intellectual property laws. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable right to access and use the service for your internal business purposes. We reserve all rights not expressly granted. If you send us feedback or suggestions, we may use them without obligation to you.

10. Third-Party Services

Langkast relies on third-party AI model providers (such as OpenAI, Anthropic, and Google) and other infrastructure providers to deliver the service. Your use of Langkast is also subject to the applicable terms and policies of these providers where relevant. We are not responsible for the availability, accuracy, or practices of third-party services.

11. Privacy

Our Privacy Policy explains how we collect, use, and protect personal information and is incorporated into these Terms by reference.

12. Confidentiality

Each party may receive non-public information from the other. The receiving party will use such information only to perform under these Terms, protect it with at least reasonable care, and not disclose it except to personnel and advisors bound by comparable obligations, or as required by law.

13. Termination & Suspension

You may stop using Langkast and close your account at any time. We may suspend or terminate your access if you materially breach these Terms, if required by law, if your use poses a security or legal risk, or if we discontinue the service — with notice where reasonably practicable. On termination, your right to use the service ends immediately. You may export Your Content before closing your account; after termination we may delete it in accordance with our Privacy Policy. Sections 7 through 18 survive termination.

14. Disclaimers

To the maximum extent permitted by law, Langkastis provided “as is” and “as available” without warranties of any kind, express or implied, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty that the service will be uninterrupted, error-free, or that outputs will be accurate. Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you.

15. Limitation of Liability

To the maximum extent permitted by law, Langkast and its affiliates will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, or goodwill, arising from or relating to your use of the service, even if advised of the possibility of such damages.

Our total aggregate liability arising out of or relating to these Terms will not exceed the greater of the amounts you paid us for the service in the twelve months preceding the event giving rise to the claim, or one hundred US dollars (US$100). These limits apply regardless of the theory of liability and do not limit liability that cannot be limited by law.

16. Indemnification

You will defend, indemnify, and hold harmless Langkastand its affiliates from any claim, demand, loss, or expense (including reasonable attorneys’ fees) arising from Your Content, your use of the service, or your violation of these Terms or applicable law.

17. Changes to These Terms

We may update these Terms from time to time. We will post the updated version on this page and revise the “Last updated” date above. If the changes are material, we will provide reasonable notice before they take effect. Continued use of Langkast after that date constitutes acceptance of the revised Terms.

18. Governing Law & Disputes

These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict of law principles. The parties will attempt in good faith to resolve any dispute informally by contacting us first. Any dispute that cannot be resolved informally will be subject to the exclusive jurisdiction of the state and federal courts located in the State of Delaware, United States, and each party consents to that jurisdiction and venue. Nothing in this section prevents either party from seeking injunctive relief to protect its intellectual property.

19. General

These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the service. If any provision is held unenforceable, the remaining provisions stay in effect. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Neither party is liable for delays caused by events beyond its reasonable control.
