Privacy Policy

Last updated: June 2026

This site and app ("TwinMiles") are operated by Strategzilla Ltd, trading as TwinMiles ("we", "us"). This policy explains what information we handle and how. We have tried to keep it short and honest.

The short version

  • You do not need an account to use TwinMiles.
  • Your practice progress, language choice and premium status are stored on your own device (in your browser), not on our servers.
  • We do not use tracking or advertising cookies.
  • Payments are handled securely by Stripe; we never see or store your full card details.

Information we handle

On-device data. When you practise, the app saves your progress, flagged questions, language preference and (if you upgrade) your premium status in your browser's local storage. This stays on your device and is not sent to us. Clearing your browser data removes it.

Payment data. If you buy Premium, payment is processed by Stripe. You enter your card details directly with Stripe, not with us. We receive confirmation that a payment succeeded, but not your card number. See Stripe's privacy policy at stripe.com/privacy.

If you contact us. If you email us, we will hold your email and message so we can reply.

Cookies

We use only essential local storage needed to make the app work. We do not use analytics, tracking or advertising cookies. See our Cookie Policy for detail. Stripe may set its own cookies during checkout to process your payment securely.

Who is responsible for your data

The data controller is Strategzilla Ltd, trading as TwinMiles. We process the limited information above to provide and support the service (our lawful basis is our legitimate interest in running the service and, for any purchase, performing our contract with you).

We do not sell your data

We do not sell, rent or trade your personal information to anyone, and we do not use it for third-party advertising.

How long we keep it

On-device data stays until you clear your browser. Email correspondence is kept only as long as needed to deal with your query and any follow-up. Payment records held by Stripe are kept per Stripe's policy and our legal obligations.

Your rights

Under UK GDPR you have rights over your personal data, including to access, correct, delete, restrict or object to its use, and to data portability. As most data stays on your own device, you can clear it yourself at any time by clearing your browser storage. For anything we hold (such as email correspondence), contact us using the details below.

If you are unhappy with how we handle your data you can complain to the UK Information Commissioner's Office (ICO) at ico.org.uk.

Children

TwinMiles is aimed at people preparing for a driving theory test (typically 17+). We do not knowingly collect personal data from children.

Changes

We may update this policy from time to time. The latest version will always be on this page.
