Privacy Policy

Last updated: 15 March 2026

Fuel Finder ("the app", "we", "us") is a free Android application that helps UK drivers find petrol and diesel prices and EV charging points near them.

This policy explains what data we collect, how we use it, and your rights. We have designed the app to collect as little data as possible.

1. What data we collect

1.1 Location

• Precise location — collected on your device when you use the Near Me, Map, Route, or Alerts screens. Used only to find stations near you or along your route. Your location is sent to our backend (Supabase, see §3) to perform the database query and is not stored in our database.
• Approximate location — used on the map screen if you grant only approximate permission.

Location is only accessed when the app is open and in the foreground. We do not collect background location.

1.2 Push notification token

If you enable price alerts, the app registers a device token with Firebase Cloud Messaging (FCM, see §3). This token is stored in our Supabase database alongside your home postcode coordinates (if set) so we can send you price alerts. The token is a random identifier and does not contain any personal information. It can be deleted by disabling alerts in the app.

1.3 Home postcode

If you enter a home postcode in Settings, the app converts it to latitude/longitude coordinates using the postcodes.io API and stores those coordinates in our Supabase database linked to your push notification token. The raw postcode text is stored on your device only; only the coordinates are sent to the server.

1.4 App preferences

Your settings (preferred fuel type, tank size, fuel efficiency, theme, map style, widget mode) are stored locally on your device using Android's SharedPreferences. They are never uploaded to our servers.

2. What we do NOT collect

• We do not collect your name, email address, or any account information. There is no account system.
• We do not collect your precise driving routes or history.
• We do not use advertising SDKs or analytics SDKs (no Google Analytics, Firebase Analytics, Crashlytics, etc.).
• We do not sell any data to third parties.
• We do not share your location with any third party beyond what is described in §3.

3. Third-party services

The app uses the following third-party services. Each has its own privacy policy.

Service	Purpose	Data sent	Privacy policy
Supabase (Ireland/EU)	Backend database — stores fuel station data, prices, and (if alerts are enabled) your push token and home coordinates	Location coordinates (per query), push token, home coordinates	supabase.com/privacy
Firebase Cloud Messaging (Google)	Delivers price alert push notifications to your device	Push notification token	firebase.google.com/support/privacy
OpenStreetMap / tile providers	Map tiles displayed in the app	Your IP address (standard web request)	osmfoundation.org
OSRM	Route calculation for the Route screen	Origin and destination coordinates	Open-source — no personal data retained
postcodes.io	Converts a UK postcode to coordinates when you set your home postcode	The postcode text you enter	Open-source — no personal data retained

Fuel station and EV charger data is sourced from the CMA Fuel Finder API (UK Government, Open Government Licence v3.0) and OpenChargeMap (Creative Commons Attribution 4.0). These are data sources only; no personal data is sent to them.

4. Data storage and retention

Data stored in our Supabase database:

• Push notification token and home coordinates — retained as long as you have price alerts enabled. Clearing your push token from the Alerts screen or uninstalling the app will cause the token to expire naturally (FCM tokens expire after ~270 days of inactivity). You can request deletion at any time — see §6.
• Fuel station and price data — public data from government and open-data sources. Contains no personal information.

Data stored on your device:

• App preferences and cached station results — stored locally and never uploaded. You can clear the cache from Settings → Clear offline cache.

5. Children

The app is not directed at children under 13 and does not knowingly collect personal data from children. The app is rated Everyone (PEGI 3) and has no features requiring user accounts.

6. Your rights

Under UK GDPR you have the right to:

• Access — request a copy of any personal data we hold about you
• Deletion — request that your data (push token and home coordinates) be deleted from our servers
• Correction — request correction of inaccurate data

To exercise any of these rights, or to ask questions about this policy, contact us at:

We will respond within 30 days.

7. Changes to this policy

We may update this policy when we add new features. The date at the top of this page will always reflect the most recent update. Continued use of the app after a policy update constitutes acceptance of the updated policy.

8. Legal basis (UK GDPR)

We rely on legitimate interests as the lawful basis for processing location data and push tokens — specifically, providing the core features of the app that users have explicitly opted into. You can withdraw your consent at any time by disabling location access in Android settings or clearing your push token from the Alerts screen.
