Terms

Version 2026-09-20. This is the version recorded against your account when you joined.

An agreement between you and Kerby LTD, a company registered in Scotland with company number SC895039, registered office 4 Coronation Gardens, Montrose, DD10 9GH. Questions to hello@gokerby.co.uk.

Who this is for

Kerby is sold to approved driving instructors and trainee instructors for use in their business. It is not a consumer service, and you are agreeing to this as a business rather than as a consumer.

You need to be entitled to teach people to drive for money in Great Britain. We do not check that, and it is your responsibility rather than ours.

What Kerby is, and what it is not

Kerby is a diary, a pupil record, a driver’s record and a set of books. It is a tool you use to run your business.

Kerby does not find you pupils, does not take bookings on your behalf, and is not a marketplace. Nobody is introduced to you by us. Any arrangement you have with a pupil is between you and them, and we are not part of it.

Kerby is not your accountant. The figures it shows are arithmetic on what you entered. What you owe HMRC is between you and them.

What it costs

£11.99 a month for Standard. It is not an introductory price and it does not step up after a year.

If you subscribe inside the iPhone app instead, it is £14.99 a month. The difference is Apple’s commission and VAT on purchases made in an app, which we do not receive. Subscribing on the website is cheaper for you and you can do it either way.

Pro is £19.99 a month on the website and £24.99 in the iPhone app. Nothing you are on today moves into it unless you choose it. On the website, moving up to Pro takes effect straight away and the rest of the month is charged at the Pro price; moving back to Standard also takes effect straight away, and the unused part of Pro comes off your next payment. In the iPhone app, Apple’s own rules for moving between plans apply.

There is no commission. Not on a lesson, not on a block, not on anything a pupil pays you. When a pupil pays by card through Kerby, the money goes to your own payment account and we never hold it.

When available and enabled, your subscription includes SMS message parts each calendar month — 100 on Standard, 200 on Pro — resetting on the first day of the month in UK time. Unused parts do not roll over. Long messages or some characters can use multiple parts. There are no automatic SMS overage charges. When the allowance is exhausted, reminders use email where an address is available. Sending and delivery are not guaranteed.

Prices exclude VAT where it applies. If we change what you pay, we will give you at least 30 days’ notice by email with the reasons, and you can cancel before it takes effect.

Payment

Monthly in advance, by card, through Stripe. Card details go to Stripe and are never held by us.

If a payment fails we will keep trying for a short grace period and tell you. After that, writing in your diary is suspended — but you keep read access to your records, and lessons already booked stay in the diary. A billing problem between you and us is not a pupil’s problem.

Your records are yours

Your pupils, your lessons, your notes and your figures belong to you. We claim no ownership of them and will not sell them, publish them or use them to build anything else.

You can export everything Kerby holds, as a file, at any time, from inside the product and without asking us. If you leave, that is how you take it with you.

You are responsible for what you put in — in particular, for having a lawful basis to hold your pupils’ details, and for what you write in a lesson note. The privacy policy explains how that works.

Data protection

Your pupils’ details are yours, not ours. In data-protection terms you are the controller of them and Kerby is your processor, which means the law requires a written contract between us about how we handle them.

That contract is the data processing agreement, and it forms part of these terms. It sets out what we do with pupil data and what we do not, the services that see it, how it is kept secure, what happens if there is a breach, and what is deleted when you leave. Accepting these terms accepts it, and the version above is the version of both.

Using it sensibly

• Keep your password to yourself; the account is yours to look after.
• Do not use Kerby to send anybody messages they have not agreed to receive.
• Do not try to reach another instructor’s data, or to get around the limits of your account.
• Do not resell Kerby or run somebody else’s driving school from one account.

Ending it

You can cancel at any time, from inside the product. Your subscription runs to the end of the month you have paid for, and we do not refund part of a month. You can close the account entirely, which removes your details and your pupils’ details — see the privacy policy for what we have to keep.

We can end it too, with 30 days’ notice. We can suspend an account immediately without notice if it is being used to break the law or to put somebody at risk, and we will tell you why and give you a way to respond.

Availability

We will keep Kerby running as well as we reasonably can, and we do not promise it will never be unavailable. There is no uptime guarantee on these terms.

Reminders are sent through third parties and delivery is not something anybody can guarantee. Treat a reminder as a help rather than as proof a pupil was told.

If something goes wrong

Nothing here limits liability for death or personal injury caused by negligence, for fraud, or for anything else the law does not allow to be limited.

Otherwise, and because this is a business-to-business service: we are not liable for lost profit, lost business, lost bookings or loss of goodwill, and our total liability in any twelve-month period is limited to what you paid us in that period.

Keeping your own records is your responsibility. The export exists so that is straightforward.

Changes to these terms

If we change anything that affects what you are agreeing to, we will email you at least 30 days beforehand and say why. Carrying on using Kerby after that is how you accept the change; cancelling before it takes effect is how you do not.

Law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
