Petrol Planner is developed by an individual UK developer (contact: support@petrolplanner.com). This page explains what data the app collects, why, and who it's shared with.
The app uses your device's location to find nearby fuel stations, plan routes, and generate map previews. Your coordinates are sent to our server as part of these requests but are not stored in our database or linked to your account.
If you create an account (email/password, Google, or Apple), authentication is handled by our processor, Supabase. We receive your email address and a session token to verify you're signed in; we don't separately store a profile beyond what Supabase manages on our behalf.
Saved addresses and vehicle details (registration, make, model, fuel type), favourite stations, and your settings are kept on your device and, if you're signed in, also stored on our servers (via Supabase) so they carry over if you sign in on another device or reinstall the app. When you use a saved address to search, its coordinates are sent as an ordinary location request, the same as if you'd entered them manually.
If you look up a vehicle by registration plate, we pass that plate to the DVSA's MOT History API on your behalf to fetch public MOT data and return it to you. We don't store your lookups in our database.
If you submit a fuel price, we store the station, fuel type, price, and a randomly generated identifier that lives only on your device — it isn't linked to your account or to any device hardware identifier.
Like most web services, our hosting provider logs technical request details (URL, including any query parameters such as coordinates or a plate number, IP address, timestamp) for a short period, used only to diagnose problems and prevent abuse.
No advertising, no selling data, no analytics or tracking SDKs.
You can delete your account at any time from the app's Settings screen — this immediately and permanently deletes your account and every car, address, favourite, and setting saved to it, both on your device and on our servers, with no need to email us. Community price reports aren't linked to an account, so they can't be individually deleted on request, but contain no personal data beyond a random on-device identifier.
Petrol Planner is not directed at children and we don't knowingly collect data from anyone under 13.
Under UK GDPR you can ask us to access, correct, or delete your data at any time by emailing support@petrolplanner.com.
If this policy changes, the "last updated" date above will change too.
