The service. FuelMetric Pro is a calculation tool for fuel-oil density at 15 °C, volume correction factors and tank quantities. It is provided by Sanaur Labs.
Your responsibility. Results depend entirely on the calibration charts, readings and settings you enter. You are responsible for checking that they are correct and for verifying important figures — especially for commercial custody transfer, billing or legal purposes — against your official documents and procedures.
Method. Calculations follow the published fuel-oil procedure of the 1980 Petroleum Measurement Tables (Tables 53B and 54B) as implemented and validated by the developer. The app is independent and is not affiliated with or endorsed by ASTM International, API or the Energy Institute. The official standards remain the reference.
No warranty. The app is provided "as is", without warranty of any kind. To the extent permitted by law, Sanaur Labs is not liable for any loss arising from the use of, or inability to use, the app or its results.
Purchases. Pro features are sold through Google Play. Billing, renewals, cancellations and refunds follow Google Play's policies; subscriptions can be managed in the Google Play app.
Your data. Your data stays on your device (see the Privacy policy). You are responsible for keeping backups.
Licence. You may use the app for your personal or business work. You may not copy, reverse-engineer, resell or redistribute the app.
Changes. We may update the app and these terms; continued use means you accept the updated terms.
