vCon Ledger

Terms of Service

Last updated: 1 August 2026

These Terms of Service ("Terms") are a legal agreement between you ("you", "your") and INBOX.KY Ltd. (a Cayman Islands company), trading as vCon Ledger ("vCon Ledger", "we", "us", "our"), governing your use of the vCon Ledger website and, where made available to you, the vCon Ledger service (together, the "Service"). By using the Service you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 18 years old (or the age of majority where you live) and able to form a binding contract. If you use the Service for an organisation, you confirm you are authorised to bind it. The Service is intended for businesses, not consumers.

2. The Service

vCon Ledger accepts signed vCon records, resolves the Billing Handle to the account that should pay, prices the event against your rate plans, posts the charge and returns a signed receipt vCon.

Release 0.1 is a working prototype, not a purchasable product. It is made available to a limited number of design partners, against a sandbox, under these Terms together with the partner arrangement we agree with you. Features, behaviour, interfaces and availability may change without notice while the Service is at this stage.

3. Design-partner access

Submitting the interest form is a request, not an agreement: it creates no obligation on us to grant access, reserves nothing and takes no payment. We may decline, pause or end a partner engagement at our discretion. Where we grant access, we will confirm the scope, the sandbox environment and any additional terms — including data-processing terms — in writing.

4. Accounts and credentials

You are responsible for your credentials, API keys and all activity under your access. Keep them secure and tell us promptly at nick@myst.ky of any unauthorised use.

5. Acceptable use

Your use of the Service is subject to our Acceptable Use Policy, which forms part of these Terms. Breaching it may lead to suspension or termination.

6. Fees

Release 0.1 is provided to design partners at no charge unless we agree otherwise in writing. Nothing on the website is an offer to sell the Service. If and when paid plans are introduced, they will be governed by the commercial terms set out in your order or quote, and no charge will be made without your prior agreement.

For the avoidance of doubt: amounts, rate codes and balances shown by the Service relate to your billing of your customers. Illustrative figures shown on this website are invented and are labelled as such.

7. Your records and your customers' data

You retain all rights to the records you submit and the charges derived from them. You grant us only the limited rights needed to operate the Service for you — to receive, validate, canonicalise, hash, resolve, price, store, back up, secure and return them.

You are responsible for the records you submit, including having a lawful basis to send them to us and any personal data they contain. Where those records contain personal data, you are the controller and we act as your processor under a separate written data-processing agreement. We handle personal data as described in our Privacy Policy.

8. Correctness statements

The correctness rules published on our website — for example idempotency by source UUID, frozen charge plans and replayable operations — describe how the Service is designed to behave. They are a description of intended behaviour at release 0.1, not a warranty or a service-level commitment, except where restated in a signed agreement or written SLA.

9. Availability, changes and "as is"

We work to keep the Service reliable but, except as expressly stated in a separate written SLA, the Service is provided "as is" and "as available" without warranties of any kind, to the fullest extent permitted by law. This is doubly true of a release 0.1 prototype: it may be interrupted, reset or withdrawn. Do not rely on it as the system of record for live customer billing without an agreement that says you may.

10. Suspension & termination

We may suspend or terminate your access if you breach these Terms or the Acceptable Use Policy, or to protect the Service, other users, or to comply with law. You may stop using the Service at any time. On termination we will handle your data per the Privacy Policy and your partner agreement and, where practical, allow a reasonable window to retrieve your data before deletion.

11. Intellectual property

The vCon Ledger name, brand, site and software are owned by us or our licensors. We grant you a limited, revocable, non-transferable right to use the Service under these Terms. You may not copy, resell or reverse-engineer the Service except as the law allows. The vCon specification itself is an open standard and nothing here claims rights in it.

12. Feedback

If you send us feedback, ideas or bug reports, we may use them to improve the Service without obligation or payment to you. This does not give us any rights in your records or confidential information.

13. Third-party services

The Service relies on third-party providers (for example hosting and email delivery). We are not responsible for third-party services outside our control, though we choose providers carefully.

14. Disclaimers & limitation of liability

To the fullest extent permitted by law:

  • we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, data, revenue or goodwill;
  • our total aggregate liability arising out of or relating to the Service is limited to the amounts you paid us for the Service in the 12 months before the event giving rise to the claim, or CI$100 if you have paid nothing — which, during release 0.1, will normally be the case;
  • nothing in these Terms excludes liability that cannot be excluded by law.

You remain responsible for the invoices you issue to your customers. We are not liable for billing decisions you make on the basis of prototype output.

15. Indemnity

You agree to indemnify and hold us harmless from claims, losses and costs arising from your misuse of the Service, the records you submit, or your breach of these Terms or the Acceptable Use Policy, to the extent permitted by law.

16. Governing law & disputes

These Terms are governed by the laws of the Cayman Islands, and you and we submit to the exclusive jurisdiction of the courts of the Cayman Islands, without regard to conflict-of-laws rules.

17. Changes to these Terms

We may update these Terms. We will post the updated version and update the date; material changes take effect on reasonable notice. Continuing to use the Service after changes means you accept them.

18. General

If any provision is unenforceable, the rest remains in effect. Our not enforcing a right is not a waiver. You may not assign these Terms without our consent; we may assign them to an affiliate or successor.
