Terms of use

Last updated 15 November 2026

Who we are

Theo is made by Callum Simpson, a sole trader in the United Kingdom. Contact: callumjohnsimpson@gmail.com. By using Theo you agree to these terms and to the licence terms of the app store you got it from.

The questions

We write Theo's questions ourselves from the Highway Code and check them carefully. They are not the official DVSA revision questions, and Theo is not approved by, made by or connected to the Driver and Vehicle Standards Agency. The rules of the road can change, so the Highway Code on GOV.UK is always the final word.

Contains public sector information licensed under the Open Government Licence v3.0.

Free and paid parts

Stage 1 and your first mock test are free. Theo Full Access is a single payment that unlocks the rest of the app for as long as Theo is available, on the Apple or Google account you paid with. Payments, refunds and receipts are handled by Apple or Google under their rules. Prices can change, but never for something you've already bought.

Your account

An account is optional. You need to be 13 or over to make one. Keep your sign-in to yourself. You can delete your account at any time in Profile.

Fair use

Please don't try to break, overload or reverse engineer Theo, get around the payment, or copy and share its questions or artwork. We can close accounts that do.

If something goes wrong

We work hard to keep Theo accurate and running, but we can't promise it will always be available or free of mistakes. We're not responsible for your test result or for losses we couldn't reasonably have foreseen. Nothing in these terms limits liability that can't be limited by law, or your rights under the Consumer Rights Act 2015.

Changes and ending

We may update Theo and these terms. If a change matters, we'll tell you in the app first. If Theo ever closes, we'll give at least 30 days' notice in the app.

Law

These terms are under the law of England and Wales. If you live elsewhere in the UK, you can also use your local courts.
