Community Preview Terms and Conditions

1. Eligibility

You may use the Community Preview only if:

• You are at least 18 and can enter into a binding contract.
• Your account information is accurate and belongs to you.
• You are not located or ordinarily resident in Russia, Iran, or North Korea and do not use the Services for those locations.
• You are not subject to applicable sanctions or trade restrictions, and providing the Services to you is lawful.

If you accept for an organisation, you confirm that you can bind it. Every person using the Software must accept the agreements and have an individual API key. We rely on these declarations without collecting date-of-birth, identity-document, geolocation, or sanctions-screening data.

2. Consumers and business users

A Consumer uses the Services mainly outside their trade, business, craft, or profession. Everyone else is a Business User. Nothing in the agreements removes rights or remedies that applicable law does not allow us to exclude.

3. Acceptance

The contract is formed when you affirmatively accept the current Terms and Software Licence through the account portal. We record the version and time before issuing or activating an API key. Downloading or installing an unmodified binary only to review the agreements is not acceptance and does not authorise execution or use.

4. Community Preview

The Community Preview is provided at no charge for evaluation. It is not a paid subscription and is not a promise of a later paid product. It has no guaranteed duration, availability, service level, maintenance, or support; may contain errors and change materially; and is not intended for safety-critical use.

The Preview does not authorise production deployment, commercial reliance, redistribution, or third-party benchmarking unless we agree otherwise in writing. We may apply reasonable technical, capacity, security, or fair-use limits.

5. Accounts and API keys

Sign-in uses your GitHub account. Each user must have a confidential, individual, non-transferable API key. Do not share, sell, publish, sublicense, or embed it in a product supplied to another person. Promptly rotate a key that is lost, exposed, or potentially compromised.

6. Software use

The Software Licence grants the applicable object-code rights. An eligible Consumer may use the Software for personal, non-commercial evaluation and development. An eligible Business User may use it for internal evaluation and development.

You may connect your own agents and tools through publicly documented external interfaces. Source access, linking, embedding, redistribution, OEM use, hosted or managed services, and integration of context-engine-core require a separate written agreement.

7. Your code and materials

You retain your rights in code and other materials used with the Software and in results produced from them, subject to our rights in the Software. The licence-verification request does not transmit repository source code, prompts, file contents, repository names, file paths, symbol names, or MCP query arguments.

8. Prohibited conduct

You must not:

• Violate the Software Licence or share credentials.
• Bypass or interfere with entitlement, licence, signature, rate-limit, or access controls.
• Disrupt the Services or probe them without authorisation.
• Use the Services unlawfully, introduce malware, attempt unauthorised access, or misrepresent eligibility.

9. Intellectual property

Context Engine and its licensors retain all rights in the Services and Software. The Software is licensed, not sold. Third-party materials remain subject to their identified licences. Voluntary feedback is licensed as stated in the Software Licence.

10. Consumer cancellation

You may stop using the Preview at any time without a cancellation fee. The Preview is free, so there is no subscription payment to refund. This does not remove statutory cancellation, digital-content, service, quality, or other consumer rights. We do not ask Consumers to waive a statutory cancellation right.

11. Changes and support

We may change, restrict, suspend, or discontinue Preview features or the Preview. We will give Consumers reasonable notice of materially disadvantageous changes where practicable unless immediate action is needed for security, law, misuse, or service integrity. No support, maintenance, compatibility, availability, or response time is promised unless agreed in writing.

12. Suspension and termination

We may suspend an account, key, or entitlement for false eligibility information, compromise, sharing, breach, or security or legal risk. We may also discontinue the no-charge Preview. For Consumers, we will act fairly and give reasonable notice where practicable unless immediate action is needed.

13. Privacy and security

The Privacy Policy explains our processing. No internet service is completely secure. Protect your GitHub account, API key, computer, repositories, and credentials and notify us of suspected compromise.

14. Warranties

The experimental Preview may be unavailable, incomplete, or incorrect. You remain responsible for reviewing its operation and output. Business User warranty disclaimers are in the Software Licence. We do not exclude non-waivable Consumer rights.

15. Liability

Nothing excludes liability that law does not permit us to exclude, including liability for death or personal injury caused by negligence, fraud, or deliberate misconduct. Consumer liability follows applicable consumer law. Business User exclusions, caps, and indemnities are stated in the Software Licence.

16. Contact and account closure

Contact legal@context-engine.app for complaints, consumer or privacy requests, account closure, compromised credentials, or legal notices. Notices may also be sent to our registered office.

17. Governing law and courts

English and Welsh law governs these Terms. Consumers retain mandatory protections of their habitual-residence country and may use courts that mandatory consumer law permits. For Business Users, the courts of England and Wales have exclusive jurisdiction, except for urgent protective relief.

18. General

You may not transfer your account, key, entitlement, or rights. We may transfer these Terms with the relevant business or assets without reducing mandatory Consumer rights. If a provision is unenforceable, the remainder continues. A delay in enforcement is not a waiver.
