Terms of Service

Last updated 29th October 2026

These terms govern your use of Tarn.hr, provided by Tarn.hr Ltd (company number SC898414) (“Tarn.hr”, “we”, “us” or “our”). By creating an account or using Tarn.hr, you agree to these terms. If you do not agree to them, please do not use the service.

1. What Tarn.hr is

Tarn.hr provides HR guidance based on UK employment law and Acas codes of practice. It does not constitute legal advice and should not be relied upon as such. Employment law is complex and turns on the facts of each case. For any situation involving significant legal risk, potential tribunal claims, or matters of particular sensitivity, you should seek advice from a qualified employment solicitor. Tarn.hr is not responsible for any decisions made on the basis of its guidance.

Tarn.hr generates guidance and documents using artificial intelligence, based on the information you provide and on our understanding of UK employment law and ACAS good practice. It is a guidance tool, not a solicitor, and using it does not create a solicitor-client relationship. You remain responsible for any decisions you make and any action you take, and you should seek advice from a qualified employment solicitor for any situation involving significant legal risk. See our Disclaimer for more.

2. Eligibility and your account

You must be at least 18 years old and using Tarn.hr for legitimate workplace or HR purposes to create an account. You are responsible for keeping your login details secure and for all activity on your account. Please tell us straight away, via our contact form, if you think your account has been accessed without your permission.

3. Plans and billing

Tarn.hr is available on a free plan, which includes one scenario per account. Paid plans are not open to new subscribers yet. When they open, they will offer up to 50 scenarios in each calendar month, counted in UTC, with every document, at £15 per month or £150 per year. Prices are shown inclusive of any applicable UK tax unless stated otherwise. We may change our prices or plans from time to time; where we do, we will give existing subscribers reasonable notice before any change takes effect for them.

Paid subscriptions are billed in advance and are processed for us by Stripe. Card and payment details are handled by Stripe and are not stored by us. Subscriptions renew automatically until cancelled, and we will email you before each renewal with the date and the amount that will be charged.

4. Cancelling, cooling-off and refunds

You may cancel a paid subscription at any time from your account settings, and cancelling is no harder than subscribing was. Cancelling stops future renewal, but you will keep access to any period you have already paid for. You can delete your account entirely at any time; this will remove your access to your scenario history, subject to our data retention obligations described in our Privacy Policy.

As a consumer, you have a 14-day cooling-off period, starting when you first subscribe and again after each renewal payment, during which you can cancel and receive a refund.

Because using Tarn.hr means immediate access to your scenarios and documents, if you use your subscription during a 14-day cooling-off period and then cancel within it, we will refund you the amount paid less a proportionate deduction for the value of what you have already used, worked out by reference to the scenarios you have run against your plan’s allowance. We tell you this, and ask you to confirm you understand it, before you subscribe; if we ever fail to do that clearly, you are entitled to a full refund regardless of use.

Outside the 14-day cooling-off period, subscription fees already paid are non-refundable, though we are happy to look at individual circumstances on request via our contact form.

Before each renewal, we will email you the date and the amount that will be charged, and remind you how to cancel. You do not need to contact us to stop a renewal: cancelling from your account settings before the renewal date is enough.

5. Acceptable use

You agree not to:

  • use Tarn.hr for any unlawful purpose, or to generate content that is misleading, discriminatory or intended to harm someone;
  • try to reverse engineer, scrape, or gain unauthorised access to Tarn.hr or its underlying systems;
  • resell, sublicense or provide the Tarn.hr service itself to third parties without our written agreement;
  • use Tarn.hr in a way that places an unreasonable load on our systems or interferes with other users’ access to the service.

We may suspend or close an account that breaches these terms, acting reasonably and, where practical, giving you the chance to put things right first.

6. Personal data you enter about other people

When you describe a workplace situation, a case, a deadline or a policy, you may enter information about employees or other people. For that information, your organisation is the controller and Tarn.hr processes it on your behalf as your processor. This section is the contract between us for that processing. We will:

  • process it only to provide Tarn.hr to you, on your documented instructions, which are these terms and the way you use the service, unless UK law requires otherwise, in which case we will tell you first unless the law prevents it; and tell you if we think an instruction would break data protection law;
  • make sure that anyone at Tarn.hr who can access it is bound by confidentiality;
  • keep it secure with appropriate technical and organisational measures, as described in our Privacy Policy and on our trust page;
  • use only the sub-processors listed on our trust page, each under written terms giving at least the same protection, which you authorise by accepting these terms, and tell you before we add or replace one so that you can object;
  • help you, as far as the nature of the processing allows, to respond to people exercising their data protection rights, and to meet your obligations on security, breach notification and impact assessments;
  • tell you without undue delay after becoming aware of a personal data breach affecting it;
  • delete it when you delete it or close your account, unless the law requires us to keep it, and let you take a copy first using the data export in your account settings;
  • give you the information you need to show that these obligations are met, and allow for and contribute to reasonable audits, including inspections, by you or an auditor you appoint.

The information concerned is whatever you choose to enter about people in your workforce, which may include special category data such as health or pregnancy. It is processed for as long as your account holds it, for the sole purpose of producing your guidance and documents. You are responsible for having a lawful basis for entering it, and for entering only what the guidance needs: Tarn.hr never needs anyone’s name.

7. Intellectual property

We own the Tarn.hr software, website, brand and underlying systems. You keep ownership of the information you enter into Tarn.hr. We grant you a licence to use the guidance and documents Tarn.hr generates for your own genuine workplace purposes, including adapting and issuing them; you should not resell or redistribute them as a standalone product.

8. Liability

Tarn.hr is provided on an “as is” basis. To the fullest extent permitted by law, we exclude all warranties as to the accuracy, completeness or fitness for a particular purpose of the guidance and documents Tarn.hr provides, and we are not liable for any loss arising from decisions made or actions taken on the basis of that guidance. Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else which cannot lawfully be limited or excluded.

Subject to the paragraph above, our total liability to you for any claim arising from your use of Tarn.hr is limited to the amount you have paid us in the twelve months before the claim arose.

9. Changes to these terms

We may update these terms from time to time, for example as Tarn.hr develops. We will post the updated version here with a new “last updated” date, and where a change is significant we will try to let existing users know in a more prominent way.

10. Governing law

These terms are governed by the law of Scotland, where Tarn.hr is registered. The Scottish courts have jurisdiction over any dispute arising from them, and if your business is based in England and Wales you may instead bring proceedings in the courts of England and Wales.
