Terms & Privacy

Last updated: June 2026 (updated to reflect WhatsApp user data storage)

Price of Petrol ("we", "us", "our") operates a WhatsApp-based fuel price finder service accessible at priceofpetrol.com. This page covers our terms of use and explains what personal data we process, why, and your rights under UK GDPR.

1. Who we are

Price of Petrol is operated by Colina. If you have any questions about this page, please contact us at the address below.

2. Terms of use

By using Price of Petrol (via WhatsApp or the website), you agree to the following:

• Free service — Price of Petrol is provided free of charge with no guarantee of availability or continuity.
• UK only — The service covers UK fuel stations only and is intended for use in the United Kingdom.
• Guidance only — Fuel prices are sourced from the UK government's mandatory reporting scheme and updated regularly, but may not reflect real-time prices at every station. Always confirm the price at the pump.
• No liability — We accept no liability for decisions made based on the information provided, including journeys made to fuel stations or any losses arising from inaccurate pricing data.
• Acceptable use — You may not use the service for commercial data scraping, automated querying, or any purpose other than finding fuel prices for personal or business use.
• Availability — We reserve the right to modify, suspend, or discontinue the service at any time without notice.

3. What data we process

When you use the WhatsApp service, we collect and store the following personal data:

• Your WhatsApp phone number — provided automatically by WhatsApp when you message us. We store this persistently so we can identify you as a returning user and remember your preferences.
• Your consent record — we store the date and time you replied AGREE to our Terms & Privacy, as evidence of your consent to use the service.
• Your fuel type preference — if you set a preference (e.g. "Diesel"), we store it against your phone number so it persists between sessions.
• Your location — only when you choose to share it during a search. Used solely to find nearby fuel stations. We do not store your location after the query is complete.
• Anonymised query logs — when you perform a search, we log the approximate area (rounded to 2 decimal places of latitude/longitude, roughly a 1km square), fuel type, and results returned. This is not linked back to your phone number.

We do not collect your name, email address, or any other personal data.

4. How we use your data

We use your data only to provide and improve the service:

• Your phone number and fuel preference are used to personalise your experience — returning the right fuel type without you needing to specify it each time.
• Your consent record is kept for legal compliance purposes.
• Your location (when shared) is used to query our fuel station database in real time and is not retained after the query.
• Anonymised query logs are used to understand which areas are most searched and to improve the service. They cannot be used to identify you.
• We do not use your data for marketing, advertising, or profiling, and we do not sell it to third parties.

5. Legal basis

We process your personal data on the basis of consent (Article 6(1)(a) UK GDPR). By replying AGREE when you first message us, you explicitly consent to us storing your phone number, consent record, and fuel preference for the purpose of operating the service. You may withdraw consent at any time by contacting us — see section 11.

6. Data sharing

We do not sell or share your personal data with third parties for their own purposes. We use the following processors to operate the service:

• Meta Platforms (WhatsApp Cloud API) — routes messages between you and us. Subject to Meta's own privacy policy.
• Vercel Inc. — hosts the application. Requests pass through Vercel's infrastructure.
• Supabase Inc. — hosts the fuel station database. Your location coordinates are used to query this database but are not stored there.

All processors are subject to appropriate data processing agreements.

7. Data retention

We retain different data for different periods:

• Your phone number, consent record, and fuel preference — retained for as long as you use the service, or until you request deletion. If you have not used the service for 24 months, we will delete your record.
• Your location — not stored at all. Used only to process your query in real time.
• Anonymised query logs — retained indefinitely as they contain no personal data.

8. Your rights

Under UK GDPR you have the right to:

• Access the personal data we hold about you
• Rectification of inaccurate data
• Erasure of your data ("right to be forgotten")
• Restriction of processing
• Object to processing based on legitimate interests
• Portability of your data in a machine-readable format

Because we hold very little data and nothing persistently, most of these rights are satisfied by the design of the service. To exercise any right, contact us using the details below.

You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.

9. Cookies and tracking

The priceofpetrol.com website does not use cookies or any tracking technologies. No analytics scripts are loaded.

10. Children

This service is not directed at children under 13. We do not knowingly process personal data from children.

11. Data deletion requests

You have the right to request deletion of your personal data at any time. To do so, email hello@colina.io with the subject line "Data Deletion Request" and include the WhatsApp phone number you used to contact us. We will delete your phone number, consent record, and fuel preference from our database and confirm within 30 days. Note that anonymised query logs do not contain your phone number and cannot be individually deleted.

Requesting deletion also constitutes withdrawal of your consent to use the service. You are welcome to restart the service at any time by messaging us again.

12. Changes to this page

We may update these terms and privacy details from time to time. The "Last updated" date at the top will reflect any changes. Material changes will be noted on the homepage.
