Privacy Policy
Last updated: 10 April 2026
1. Who we are
FuelHound is developed by Lunaire Labs, operating from the United Kingdom. For the purposes of the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, the data controller (to the very limited extent any data controller role applies) is Lunaire Labs.
Contact: support@lunairelabs.uk.
Because FuelHound does not collect, receive, or process any personal data on any server, the traditional obligations of a data controller with respect to your app data do not arise in practice. All processing happens on your device, under your sole control. This policy is provided for full transparency.
2. What data FuelHound handles
Location (on-device only)
FuelHound asks for location permission so the map can center on where you are and find nearby fuel stations. Your GPS coordinates are processed entirely on your device and are never sent to Lunaire Labs or any other party. We have no servers and no way to receive your location even if we wanted to.
Preferences
Your selected country, preferred fuel type, theme choice, and last map position are stored locally on your device using Android's standard preference storage (DataStore). They never leave your phone.
What we don't collect
- No accounts. FuelHound never asks you to sign in.
- No analytics. We do not use Google Analytics, Firebase Analytics, Crashlytics, or any other analytics or crash-reporting SDK.
- No advertising. FuelHound shows no ads and contains no advertising SDKs.
- No personal identifiers. We do not collect your email, phone number, device ID, advertising ID, or any other personal identifier.
- No sync. Your settings and saved map position never leave your device.
3. Third parties FuelHound talks to
To show you fuel prices and render the map, FuelHound makes network requests to these third parties directly from your device:
Google Maps (map rendering)
FuelHound uses the Google Maps SDK for Android to draw the map. When the map loads, Google receives your IP address and the area you're viewing (standard for any mapping service). Google's use of this information is governed by the Google Privacy Policy. We do not share any additional information with Google.
Government fuel price feeds
FuelHound fetches live fuel prices from the following official open-data sources. These are public feeds — no API key or personal information is sent:
- United Kingdom: Fuel Finder scheme (CMA) — 13 registered retailers including BP, Shell, Tesco, Asda, Sainsbury's, Morrisons and others.
- France: prix-carburants.gouv.fr (Ministry of Economy open data).
- Spain: MITECO (Ministerio para la Transición Ecológica).
- Italy: MIMIT (Ministero delle Imprese e del Made in Italy).
- Portugal: DGEG (Direção-Geral de Energia e Geologia).
- Germany: Tankerkoenig (MTS-K government feed).
- Austria: e-Control (spritpreisrechner.at).
OpenStreetMap (fallback station data)
For stations that do not report prices to the official feeds, FuelHound shows station locations from OpenStreetMap via the Overpass API. Your query (a bounding box of the visible map area) is sent to Overpass, and their use of this information is governed by the OSM Foundation Privacy Policy.
Navigation hand-off
When you tap the "Directions" button on a station, FuelHound launches the navigation app you've set as default on your phone (for example Google Maps or Waze). FuelHound does not know which app you launch, and we send no data to those apps beyond the destination coordinates embedded in the Android geo: intent.
4. Legal basis under UK GDPR
Where any personal data is incidentally processed (for example, an IP address being visible to Google when the map tiles load), the legal basis is legitimate interest — you have chosen to open a mapping application and must necessarily reach the map server to render it.
5. Your rights
Under UK GDPR you have rights of access, rectification, erasure, restriction, portability and objection. Because FuelHound stores your data only on your device, you can exercise all of these rights yourself at any time:
- Access and portability: Open the app; everything is there.
- Rectification: Change any setting in Settings.
- Erasure: Clear the app's data via Android's Settings → Apps → FuelHound → Storage → Clear Data, or uninstall the app.
6. Children
FuelHound is not directed at children under 13 and does not knowingly collect any information from children.
7. Changes to this policy
If we change this policy we will update the "Last updated" date at the top. Material changes will be reflected in app updates and noted on this page.
