These Terms and Conditions ("Terms") are an agreement between you and d4vinder Ltd, trading as d4, a company registered in England and Wales under number 17149864 ("we", "us"), and govern your use of the Driving School Diary iPhone app ("the app"). By downloading or using the app you agree to these Terms. If you do not agree, do not use the app.
We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app on Apple devices that you own or control, in line with the Apple Media Services / Licensed Application End User Licence Agreement and these Terms. You may not copy, redistribute, rent, resell or reverse engineer the app except as permitted by law.
The app is a private diary and business tool for a single UK driving instructor. It helps you schedule lessons, keep pupil records, track progress against the DVSA standard, raise invoices, record payments, and manage expenses and mileage. It is a record-keeping and scheduling aid; it is not professional, legal, financial, tax or driver-training advice.
You must be at least 18 and use the app for your own driving-instruction activity in the United Kingdom. You are responsible for the way you run your business, including your bookings, cancellations, pricing, teaching, invoicing, and your tax and regulatory obligations, and for the accuracy of the information you enter.
When you store information about your pupils, you are the data controller for that information under UK data protection law. You are responsible for having a lawful basis to hold it, for giving your pupils the privacy information they are due, and for keeping it accurate and secure. As explained in the Privacy Policy, this data stays on your device and your own private iCloud and is never sent to us.
Pupils pay you directly. The app never holds, transmits or processes lesson money. The payment features record cash and bank transfers you have taken, and build a link or QR code to your own PayPal.me or Stripe payment link; those payments are handled by PayPal or Stripe under their terms and settle into your account. If you connect a SumUp account and take a contactless card payment on the device, that payment is processed by SumUp Payments Limited under your agreement with them, subject to the Tap to Pay on iPhone terms and conditions from Apple, which you accept on first use, and settles into your own SumUp account. Receipts the app produces are records of what you have entered, not proof that funds have cleared. You are the merchant for those payments and are solely responsible for refunds, chargebacks, any processing fees, receipts, and complying with the rules of those services and with consumer law, including the UK ban on charging consumers a surcharge for paying by card.
Your data is stored on your device and, if you enable it, your own private iCloud. You are responsible for keeping your device secure and for maintaining backups; the app offers an export you can use. We are not able to recover data that is lost from your device or iCloud.
The app is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any implied warranties of satisfactory quality, fitness for a particular purpose and non-infringement. We do not warrant that the app will be uninterrupted or error-free, that its calculations, reminders or syllabus references are free from error, or that it is compatible with every device or iOS version. Highway Code and DVSA references are provided for convenience and may change; always check the current official guidance.
Nothing in these Terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud. Subject to that, and to the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special or consequential loss, or for any loss of data, bookings, income, profit or business, arising out of or relating to your use of, or inability to use, the app. This does not affect your statutory rights as a consumer.
We may update the app and may change these Terms from time to time. The current version will always be posted at this address with a new date. Continued use of the app after a change means you accept the updated Terms.
These Terms are between you and us, not Apple, and Apple is not responsible for the app or its content. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Your use of the app must also comply with the applicable Apple terms.
Driving School Diary is an independent app built by d4. DVSA, HMRC, the Highway Code, PayPal, Stripe, SumUp, WhatsApp and other names are the property of their respective owners and are used only to describe compatibility or function. Apple, the Apple logo, iPhone, iPad, Apple Pay, Apple Watch, CarPlay, Siri, Face ID and Tap to Pay on iPhone are trademarks of Apple Inc., registered in the U.S. and other countries and regions. The app is not affiliated with, sponsored by or endorsed by any of them.
These Terms are governed by the laws of England and Wales, and the courts of England and Wales have non-exclusive jurisdiction. Nothing here limits any statutory consumer rights you may have.
