Terms of Service

Heoka Partners Limited, company number 16516554, registered in England and Wales. "Heoka", "we", "us". You, the business named on the order, "you".

Last updated: 21 August 2026

1. What you are buying

Harness is hosted software. We run it for you at api.heoka.co.uk. ChatGPT and Claude can read the same queue through a connector at mcp.heoka.co.uk.

You are buying a monthly subscription to that hosted service, not a copy that runs on your laptop, and not a Heoka-hosted AI model. Your books and your mail stay in the tools you already pay for. The chase queue, the drafts waiting for your tap, and the logins you connect are stored on our servers.

If Heoka or the hosted service is down, the queue does not update. That is the honest version of "where it runs".

The short commercial version of price, trial, cancel and refund is also on /terms. If the two pages ever disagree, email connor@heoka.co.uk and we will fix the page, not argue the gap.

2. Licence

We grant you a non-exclusive, non-transferable right to use Harness for your business, for as long as your subscription is current.

You may not resell it, sublicense it, or try to break the approval gate. The software stays ours. You own your business data and anything Harness produces from it. We process that data only to provide the service.

3. The approval gate, stated precisely

Harness will not send an email, a message or a document to any third party until you have approved that specific item. This is enforced in code before any send, not by a setting you could leave switched off.

Two things that are not covered by that sentence:

1. Reading. When you connect a ledger or an inbox, Harness contacts it to read your data. That is inbound, and it is what you connected it for.
2. Drafting. To write a chase, context from your queue is sent to an AI model. When you connect ChatGPT or Claude as a connector, that uses your account under your agreement with them. We do not currently run overnight drafts on a Heoka-held AI key. Overnight we sync your ledger and build the chase queue. Drafts wait for you (or your connected AI) to write and for you to approve.

4. Your AI account and the connector

Harness is built to sit next to the ChatGPT or Claude account you already pay for. That relationship is between you and that provider. Their terms, pricing, limits and outages are outside our control.

The connector lets ChatGPT or Claude read the queue and prepare work. It cannot send mail to a customer. Sending still needs your tap.

The first seven days exist so you can try that connector and the queue on your own books. If the connector does not work, tell us. Cancel before day 8 and you are not charged. If you have already been charged and we cannot make it work, we refund that month.

5. What you are responsible for

• Everything you approve. Approving is the act that sends it. Read it first.
• The accuracy and legality of what goes out in your name, including UK marketing, spam and data protection rules when Harness chases on your behalf.
• Keeping your own accounts and credentials secure, and telling us if you think a connection is wrong.
• Your ChatGPT or Claude bill, if you use those products.

6. AI output

Language models get things wrong, including confidently. Every draft is presented for approval because it needs a human decision.

We do not warrant that any draft is accurate, appropriate or fit for a particular purpose. Figures about your own records come from your connected tools by query rather than from the model, but you remain responsible for checking anything before you act on it or send it.

7. Acceptable use

Do not use Harness to send unlawful, deceptive or unsolicited bulk messages, to impersonate anyone, or to process data you have no right to process. We may suspend an account being used this way. In practice we would call you first.

8. Payment, trial, cancellation and refunds

Price. The first 50 companies pay £19 a month including VAT, per company, for as long as that subscription runs without a break. After those 50 places, new customers pay £49 a month. Card details go to Stripe and never to us.

Trial. The first 7 days are free. A card is taken today. You are charged £19 on day 8 unless you cancel before then. The 7 days are for you to connect your ledger, see the queue, and try the ChatGPT or Claude connector.

Cancel. Email connor@heoka.co.uk or WhatsApp. No notice period, no cancellation fee. If you cancel during the trial, you are not charged. If you cancel after a paid month has started, the service runs to the end of that month and we do not bill you again. We do not refund part of a used month except as below.

Refunds. If Harness does not work for you and we cannot fix it, we refund your current month. Consumers may have additional rights that this page cannot take away.

Done-for-you work is a separate £950 deposit: we audit, build and test. If you want it running after that, monthly at an amount we agree from the scope. That is not part of the £19 subscription.

9. Support and availability

We do not offer an uptime guarantee. We are a very small company. The hosted service can be down. If it is, we will say so honestly and fix it.

What we commit to is a human reply the same working day where we can, and always within one working day, Monday to Friday, UK hours. WhatsApp is fastest when something has stopped. Email is for billing, cancellation, or a data request.

10. Changes

We may change these terms. If a change materially affects what you get, what it costs, or where your data goes, we will tell you before it takes effect. If you do not accept it, cancel and we will refund the unused part of the month.

11. Liability

We provide Harness with reasonable skill and care. Our total liability to you in any twelve month period is limited to the fees you paid us in that period.

We are not liable for indirect or consequential loss, for lost profits, for the acts of your AI provider, your ledger, or your mailbox, or for anything sent as a result of an approval you gave.

Nothing here limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be limited by law.

12. Termination

You may cancel at any time. We may terminate for non-payment or for a breach of section 7. On termination your access ends. You can ask us to delete the data we hold about your Harness account. Your books and your mail stay in the tools you already pay for. We cannot delete those, because they were never ours.

13. Governing law

England and Wales, exclusive jurisdiction of its courts.
