Terms of Service.

1. Definitions

“KYE™”, “we”, “us” means KYE Protocol™ Ltd, a company registered in England and Wales (registered office to be confirmed; contact info@kyeprotocol.com). “Customer”, “you” means the legal entity accepting these Terms via the pilot-apply form or a separately negotiated order form. “Services” means the KYE Protocol™ software-as-a-service offering, including KYE Cloud™, KYE Gateway™, KYE Evidence Gateway™, KYE Delegated Auditability™, KYE Developer Tools™ and the KYE AI Agent Audit Pilot™ programme. “Pilot” means the bounded engagement described in Delegated Auditability™ and constitution doc 21.

2. The services

We grant you a non-exclusive, non-transferable right to access and use the Services during the term, solely for your internal business operations and subject to these Terms, the Acceptable Use Policy, and any applicable order form. We may modify, update or improve the Services at any time; material changes will be notified to you by email.

Pilots run under the read-only Stack Binding contract. No production action of yours is blocked by the Services unless and until you have signed an Adoption Stage transition promoting a Guard to enforce.

3. Pilot fees

Pilot fees are agreed in the qualifying call and recorded in an order form. Default pilot pricing is fixed-fee for a 30 to 90 day engagement and covers binding, observation, Shadow Evaluation, Authority Gap classification and the signed Audit Pilot Report. Production deployment beyond the pilot is contracted separately. All fees are payable in GBP, EUR or USD as specified in the order form, exclusive of VAT and any other applicable taxes, within 30 days of invoice.

4. Confidentiality

Each party will treat the other's Confidential Information with at least the same degree of care it uses to protect its own confidential information of similar sensitivity, and in no event less than a reasonable degree of care. Confidential Information includes pricing, technical implementation details, observed-action records, Authority Gap analyses, the contents of any Evidence Pack™ and any data we observe through Stack Bindings on your behalf. This clause survives termination for five years.

5. Intellectual property

The KYE Protocol™ specifications, schemas, OpenAPI contracts, conformance fixtures and SDK source code are licensed under the Apache 2.0 licence (see the GitHub organisation) and that licence governs your use of those open components. All other IP in the Services, including KYE Cloud™, KYE Gateway™, the operational engines (Authority, Purpose, Decision, Evidence, Replay, Directory, Ecosystem, Entity, State, Rules), the KYE Evidence Gateway™ ingest tier and the Guard Recommendation generator, is owned by KYE Protocol™ Ltd. You retain ownership of all Customer Data (defined in the Privacy Policy); you grant us a limited licence to process Customer Data solely to deliver the Services.

6. Trademarks

The marks KYE™, KYE Protocol™, Know Your Entity™, and every KYE-* trademark listed in the constitution at 01-NAMING.md §15 (including, without limitation, KYE Delegated Auditability™, KYE Shadow Mode™, KYE Evidence Gateway™, KYE AI Agent Audit Pilot™, KYE Decision Map™, KYE Evidence Pack™, KYE Authority Gate™, KYE Replay Proof™, KYE Purpose Permission™, KYE Authority Graph™, KYE Directory™, KYE Cloud™, KYE Gateway™, KYE Partner Rail™, KYE Developer Tools™, KYE Admin Console™) are trademarks of KYE Protocol™ Ltd or its affiliates. You may use them only as expressly permitted in the Trademark Policy linked from /legal.

7. Warranty disclaimers

The Services are provided on an “as is” and “as available” basis. To the maximum extent permitted by law, KYE™ disclaims all warranties, whether express, implied or statutory, including any warranties of merchantability, fitness for a particular purpose, title and non-infringement. KYE™ does not warrant that the Services will be uninterrupted or error-free, or that the Services will detect every Authority Gap in your AI-agent fleet. The Services are an observability and decision-support tool; you remain responsible for your own production decisions and your compliance with applicable law.

8. Limitation of liability

To the maximum extent permitted by law, neither party will be liable to the other for any indirect, incidental, consequential, special, punitive or exemplary damages, or for loss of profits, revenue, goodwill, data or use, arising from or related to these Terms. Each party's total aggregate liability under these Terms in any twelve-month period will not exceed the fees paid or payable by you to us in that period. Nothing in these Terms limits or excludes liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability that cannot be limited or excluded under English law.

9. Term and termination

These Terms commence on the date you accept them and continue until terminated. Either party may terminate for material breach not cured within 30 days of written notice. We may suspend the Services immediately if you breach the Acceptable Use Policy or fail to pay undisputed fees within 30 days of their due date. On termination, we will, at your written request received within 30 days, return or delete your Customer Data in accordance with the Data Processing Agreement. Clauses 4 (Confidentiality), 5 (IP), 6 (Trademarks), 7 (Disclaimers), 8 (Liability), 10 (Governing law) and 11 (Notices) survive termination.

10. Governing law and jurisdiction

These Terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute arising from or related to these Terms, save that we may seek injunctive relief in any court of competent jurisdiction to protect our intellectual property or Confidential Information.

11. Notices

Notices to KYE Protocol™ Ltd must be sent to info@kyeprotocol.com and are deemed received on the next business day. Notices to you will be sent to the email address provided in the pilot-apply form or in your order form.

12. Miscellaneous

If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions remain in full force. Neither party may assign these Terms without the other's prior written consent, except in connection with a merger, acquisition or sale of substantially all assets. These Terms, together with the Privacy Policy, the Acceptable Use Policy, the Data Processing Agreement (if applicable) and any order form, constitute the entire agreement between the parties regarding the Services.
