Privacy Policy

Last updated: April 2026

1. Data Collection

We do not collect any personal data. The app does not use analytics or tracking services, and does not use advertising SDKs. FuelFile does not access your location, contacts, or microphone, does not create user accounts or require login, and does not transmit any data to servers operated by us.

The app functions entirely offline. An internet connection is only required for the optional Pro purchase and for restoring purchases.

2. Local Data Storage

All data is stored exclusively on your device: vehicles, receipts and receipt data in a local SQLite database, the raw receipt text read during recognition (OCR), receipt photos in the app's local file system, and app settings (language, currency, theme).

This data never leaves your device. It is not transmitted, uploaded, or synced. Uninstalling the app removes all locally stored data.

3. Text Recognition (OCR)

Receipt text recognition runs entirely on-device via Google ML Kit. Neither receipt photos nor recognized text are sent to any server.

4. Permissions

Camera — to scan fuel receipts directly in the app. Photo library — to import receipts you have already saved.

Both permissions are used only for the respective action.

5. Export & Delete Your Data

You can export all app data as a JSON file (local backup) or delete it completely at any time. Since no servers are involved, deletion is immediate and permanent.

6. Third-Party Services

FuelFile uses a single third-party service — solely for purchases: RevenueCat processes and validates the Pro subscription. RevenueCat receives an anonymous user ID and the purchase receipt from Apple or Google. No personal data (name, email, location) is sent.

7. Other Platform Features

When you share an export, your device's native share dialog opens. The shared content is handled entirely by your device's operating system — we do not process or store it.

The app may occasionally ask you to rate it using the standard platform dialog. No data is collected through this process.

8. Children

FuelFile collects no data from any user, including children.
