FuelSync ("the Application"), developed by Onest Tech ("we," "us," or "our"), is engineered from the ground up as an offline-first vehicle management, mileage tracking, and peer-to-peer audio tool. We believe that your driving routes, fuel expenses, and vehicle documents belong exclusively to you.
FuelSync does not operate user accounts, login authentication, or cloud databases. All vehicle logs, fuel entries, odometer readings, and notes are stored strictly in a local SQLite database sandboxed on your personal mobile device. We do not transmit, sell, or sync your data to remote cloud servers.
FuelSync contains zero advertising SDKs, zero user tracking trackers, and zero analytical trackers. Map tiles are fetched directly from OpenStreetMap servers with standard user-agent attribution.
You retain 100% ownership of your data. You can export your data as JSON or CSV files at any time, or permanently delete all vehicles and logs using the in-app "Delete Data" feature in Settings.

FuelSync is designed as an informational vehicle assistant. You agree not to interact with or adjust the Application while operating a motor vehicle. Always pull over to a safe location before logging fuel, configuring intercom rooms, or scanning receipts.
Tour Intercom operates over direct Wi-Fi and Bluetooth radio frequencies. Communication range varies depending on terrain, line of sight, and environmental interference. Onest Tech makes no guarantee of uninterrupted communication during emergency situations.
Because FuelSync is 100% offline, your data exists only on your device. It is the user's responsibility to periodically create backups using the in-app export tools. Onest Tech is not responsible for data loss resulting from device loss, damage, or operating system resets.
Welcome to the official FuelSync Support Center. FuelSync is engineered by Onest Tech to deliver seamless, privacy-first vehicle tracking, fuel economy monitoring, and offline tour intercom. If you encounter any issues, have questions, or would like to request new features, we are here to support you.
