Privacy Policy

Introduction

PetrolFinder.uk (“we”, “us”, “our”) is a free fuel price comparison service for the United Kingdom. We are committed to protecting your privacy and complying with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. This policy explains what personal data we collect, how we use it, and your rights regarding that data.

What Data We Collect

When you create an account and use PetrolFinder.uk, we may collect the following data:

• Account information: Your name and email address, collected and managed through our authentication provider, Supabase Auth.
• Station reviews: Star ratings and review text you submit for fuel stations. When you submit a review, your display name is derived from the local part of your email address (the part before the @). For example, if your email is [email protected], your review will appear under the name “jane.smith”. This name is visible to all visitors.
• Price confirmations: When you confirm a fuel price at a station, we record the confirmation along with your user identifier.
• Fuel logbook entries: Vehicle information (make, model, registration) and fill-up records (date, station, litres, cost) that you voluntarily add to your logbook.
• Receipt images: If you use the receipt scanning feature, your receipt image is sent to Google Gemini for data extraction. We do not store the receipt image itself — only the extracted data (fuel type, litres, price, station) is saved to your logbook.
• Location data: If you use the “Use my location” feature, your browser will ask for permission. This data is used solely to find nearby stations and is not stored.
