These Terms of Use govern your access to and use of kaironull.com and the KairoNull Umbra Trust Protocol platform ("Platform"). By using this website or Platform, you agree to these terms.

1. Acceptance

By accessing kaironull.com or using any KairoNull service, you confirm that you are at least 18 years old and authorised to act on behalf of the organisation you represent (if applicable).

2. The Platform

The Umbra Trust Protocol is an AI governance evidence infrastructure service. It captures, hashes, chains, and stores evidence of AI decisions for regulated organisations. It does not provide legal advice, compliance certification, or regulatory approval of any kind.

Evidence records generated by KairoNull are technical outputs. Their legal sufficiency for any specific regulatory purpose depends on your jurisdiction, applicable law, and your deployment context. You are responsible for assessing whether KairoNull evidence meets your regulatory obligations.

3. Free tools

The public verification tool at kaironull.com/verify and the deadline tracker at kaironull.com/deadline are provided free of charge, without warranty. We make no representation that these tools are complete, accurate, or current at any given moment.

4. Acceptable use

You must not:

• Use the Platform to falsify, tamper with, or misrepresent AI decision records.
• Attempt to reverse-engineer, copy, or resell any part of the Platform without a written licence.
• Use the Platform in violation of applicable law or to facilitate illegal activity.
• Submit material that contains malicious code, constitutes spam, or violates third-party rights.

5. Intellectual property

All content on kaironull.com, including the Umbra Trust Protocol methodology, is owned by KairoNull and protected by copyright. You may not reproduce or distribute it without written permission, except for brief quotation with attribution.

6. Limitation of liability

To the maximum extent permitted by law, KairoNull's total liability arising from use of the Platform or website is limited to the amount you paid us in the three months preceding the claim. We are not liable for indirect, consequential, or regulatory losses, including regulatory fines.

7. Disclaimer

The Platform and website are provided "as is." We disclaim all warranties, express or implied, including fitness for a particular regulatory purpose.

8. Governing law

These terms are governed by English law. Disputes are subject to the exclusive jurisdiction of the courts of England and Wales.

We may update these terms. We will notify newsletter subscribers of material changes. Continued use after the effective date constitutes acceptance.
