Privacy Policy for TripCost
Effective date: 7 October 2026
TripCost is designed to keep your journey and calculator data private. The app does not sell, rent, or share your personal data with advertisers, analytics providers, or data brokers. TripCost does not track you across apps or websites.
Most TripCost data stays on your device. Some optional features, such as iCloud Sync, TripCost Pro, and GOV.UK Fuel Finder price search, use Apple or backend services only as needed to provide the feature you choose to use.
Information Stored by the App
TripCost stores information you enter or choose so the app can provide its core features. This may include:
Fuel price, MPG, distance, budget, and cost values entered into the calculator
Split-cost settings and related calculation results
Saved journey history
Optional journey names
Journey dates, costs, cost per mile, cost per person, and other calculation results
App preferences such as currency, appearance, default fuel price, Fuel Finder fuel type, search radius, station sort order, and iCloud Sync settings
If you save a selected fuel station as your default, the station name, station ID, address or postcode where available, coordinates where available, selected fuel type, last known fuel price, and update timestamps
This information is stored locally on your device unless you enable iCloud Sync or use an online feature described below.
iCloud Sync
TripCost includes optional iCloud Sync for journey history. If you enable iCloud Sync, your journey history is stored in your private iCloud database using Apple CloudKit so it can sync between your Apple devices.
Your iCloud data is managed by Apple and tied to your Apple Account. TripCost does not use iCloud data for advertising, analytics, profiling, or tracking.
To learn about changes made on your other devices, TripCost registers with Apple's push notification service when the app launches. These are background notifications delivered by Apple to tell the app that iCloud data has changed. They are not used for marketing, and TripCost does not send the push token to its own backend.
You can turn iCloud Sync off in the app settings. You can also delete TripCost data stored in iCloud from the iCloud Sync settings screen.
TripCost Pro and Purchases
TripCost Pro subscriptions are purchased through Apple's App Store in-app purchase system. Apple processes the payment and manages billing, refunds, renewals, and subscription status. TripCost does not receive your payment card details or billing address.
TripCost uses StoreKit subscription information to decide whether Pro features are available. The app may store a local entitlement cache, including the active product ID and Apple's signed transaction data, so Pro access can continue briefly when your device is offline.
For Pro-only Fuel Finder features, TripCost sends Apple's signed transaction data to the TripCost Supabase backend so the backend can verify that the subscription is active before returning GOV.UK fuel price data. This verification is used only to provide Pro features and to diagnose verification failures.
If a subscription check fails, is expired, or is revoked, the backend may record a diagnostic entry for troubleshooting. It contains the time, the reason for the failure, the product ID, the app's bundle ID, the App Store environment, and technical details about the signed data. It does not contain the signed transaction itself, your name, or your Apple Account details.
GOV.UK Fuel Finder Price Search
TripCost Pro includes optional GOV.UK Fuel Finder price search for UK fuel stations. Manual fuel price entry remains available without using Fuel Finder.
When you search by current location, TripCost asks iOS for When In Use location access. If you allow it, the app sends your device's current latitude and longitude (to roughly 100 metres accuracy), search radius, selected fuel type, result limit, and Pro entitlement proof to the TripCost Supabase backend. TripCost does not request background location access and does not continuously track your location.
When you search by town, road name, place, or postcode, the app sends the search text, search radius, selected fuel type, result limit, and Pro entitlement proof to the TripCost Supabase backend. The backend may use Postcodes.io and, where configured, Ordnance Survey OS Names API to resolve the search text to an approximate UK location.
The backend uses the official GOV.UK Fuel Finder API and cached official fuel price data to return matching stations and prices. Fuel Finder responses may include station names, addresses, postcodes, coordinates, prices, fuel types, update timestamps, source metadata, and attribution.
The TripCost backend caches Fuel Finder lookup results so repeated searches in the same area load quickly. Each cache entry stores the coordinates searched (your device's coordinates for a current-location search, or the point that a town, road, place, or postcode resolved to), the search radius, the fuel type, and the results returned. It does not store your search text, your account details, or a device identifier. Cache entries are cleared whenever the backend publishes a new set of fuel prices, usually within about six hours, but they can be kept for longer if a price refresh is delayed.
The backend may also process normal technical request data, such as IP address and request metadata, for hosting, security, debugging, abuse prevention, and reliability. TripCost does not use Fuel Finder lookup data for advertising, analytics, profiling, or tracking.
If you save a station as your default fuel price source, TripCost stores that station information locally on your device. While you have TripCost Pro, the app automatically refreshes the selected station's price from time to time, such as when you open or return to the app or open Settings, without you starting a search. To do this, the app sends the saved station's coordinates (not your current location), selected fuel type, search radius, and Pro entitlement proof to the backend.
Directions
If you choose to open directions to a fuel station, TripCost opens the maps app you pick: Apple Maps, or Google Maps or Waze if they are installed on your device. The station name and coordinates (or address where coordinates are not available) are passed to that app, which handles them under its own privacy practices. To show which of these apps you can choose, TripCost checks on your device whether Google Maps and Waze are installed. This check stays on your device and nothing is sent anywhere.
Data Sharing
TripCost does not send your calculator entries or saved journey history to the developer's backend. Feature-specific data, such as Fuel Finder search details and Pro entitlement proof, is sent only when needed for the optional features described in this policy.
TripCost shares data only when needed for features you choose to use:
Apple processes App Store purchases, subscription status, iCloud Sync data, push notification delivery for iCloud Sync, and Apple Maps directions.
Supabase hosts the TripCost Fuel Finder backend and processes Fuel Finder requests for Pro users.
GOV.UK Fuel Finder provides official UK fuel station and price data.
Postcodes.io and Ordnance Survey OS Names API may be used by the backend to resolve UK place, road, or postcode searches.
Google (Google Maps) or Waze receives the station location from your device if you choose either of them for directions.
If you export journey history as a CSV file, the file is shared only with the destination you choose using the iOS share sheet. TripCost does not receive or control what you do with exported files after sharing.
Tracking and Analytics
TripCost does not track you across apps or websites.
TripCost does not include third-party advertising SDKs, third-party analytics SDKs, or tracking technologies.
Permissions
TripCost may request When In Use location access if you choose to search for nearby GOV.UK fuel prices. Location access is optional. You can deny or revoke location access in iOS Settings, and you can still enter fuel prices manually or search Fuel Finder by town, road, place, or postcode where available.
TripCost does not request access to your contacts, camera, microphone, photos, or other sensitive device data for its core calculator features.
Data Retention and Deletion
Calculator inputs, settings, selected default station details, local Pro entitlement cache, and journey history remain on your device until you delete them, clear your journey history, change settings, or uninstall the app.
If iCloud Sync is enabled, synced journey history may remain in iCloud until you delete it using the app's iCloud data deletion option or manage it through your Apple Account or iCloud settings.
Fuel Finder lookup cache entries on the TripCost backend, including the search coordinates described above, are kept until the next fuel price refresh is published, usually within about six hours, and longer if a refresh is delayed. Fuel Finder source data is refreshed from the official GOV.UK Fuel Finder service. Diagnostic entries for failed subscription checks are kept on the backend for troubleshooting.
Children's Privacy
TripCost does not knowingly collect personal information from children.
Changes to This Policy
This privacy policy may be updated from time to time if TripCost's features or data practices change. Any updates should reflect the current behavior of the app.
