OptiFuelUK Privacy Policy

Last updated: 26 May 2026.

OptiFuelUK (“the app”, “we”) helps UK drivers find the cheapest fuel along a planned driving route. This policy explains what data the app handles and where it goes.

Short version

• No accounts. Nothing to sign up for. No login.
• No analytics, advertising or tracking. The app contains no third-party SDKs of any kind.
• Everything personal stays on your device. Your vehicle profile, recent routes, and journey history are stored locally via SwiftData. We can’t see them; nobody else can either.
• The only outbound network traffic is to Apple (for maps and routing) and to the UK Government’s Fuel Finder service (for fuel prices).

What the app stores on your device

• Vehicle profile — fuel type, fuel efficiency, tank capacity, “refill from” threshold.
• Recent routes — start and end coordinates plus addresses of routes you’ve planned. Capped at the 20 most recent.
• Journey history — when you tap one of the navigation-app export buttons, a record is saved with the route, the petrol station you picked, the price, and how much you saved versus the on-route baseline. Used to show your lifetime savings on the Journeys tab.

All of this lives in iOS’s protected app sandbox. Deleting the app removes everything. You can delete individual recent routes and journeys at any time by swiping left on them inside the app.

What the app sends off your device

Request	Sent to	Why
Address autocomplete keystrokes	Apple (MKLocalSearch)	To resolve “M62 services” to a coordinate
Route calculation requests	Apple (MKDirections)	To compute driving routes and detour distances
client_credentials OAuth flow	UK Gov Fuel Finder (fuel-finder.service.gov.uk)	To authenticate the data fetch
Forecourt + price feed fetch	UK Gov Fuel Finder (fuel-finder.service.gov.uk)	To get the data the app ranks

Apple’s services are subject to Apple’s Privacy Policy. The UK Government’s Fuel Finder API publishes data under the Open Government Licence v3.0.

The app does NOT send: your location, your vehicle profile, your recent routes, your journey history, your home address, or anything else identifiable.

Location

If you tap “Use current location” when planning a route, iOS asks for the standard When-In-Use permission. The latitude/longitude that comes back is used only to set the route’s start point on your device. It is not transmitted anywhere. Deny the permission and the app continues to work — you just type the start address instead.

Third-party navigation apps

When you tap “Apple Maps”, “Google Maps” or “Waze” from a ranked station, the app constructs a deep-link URL (containing the route coordinates) and hands it to iOS to open in the chosen app. From that point onward you’re using the navigation app’s own privacy controls, not ours. We don’t see what happens after the hand-off.

Children

The app is suitable for general audiences and does not knowingly collect data about anyone. Apple’s App Store age rating is 4+.
