Fuellin: Fuel Log · Support
Fuellin Support
Help with fuel entries, mileage, backups, reports, purchases, or app access.
Updated October 9, 2026
Before contacting support
- Check that the correct vehicle and units are selected.
- Mileage needs suitable full-tank endpoints; partial refills stay pending until the next full tank.
- For purchase issues, confirm that you are signed in to the same Google Play or Apple account used to buy Premium, then use Restore Purchases. A pending payment does not unlock Premium.
- For backup issues, keep the original local data and do not overwrite your only backup.
What to include
Include the app version, device model, operating-system version, and a short description of what happened. Never send a password, Google or Apple access token, full store receipt, or complete backup file by ordinary email.
Privacy and deletion
Fuellin has no developer account to delete. Local records and optional backup snapshots are controlled from the app. Deleting records or uninstalling does not cancel Premium: manage the subscription through the purchasing store. See the project privacy and data-deletion pages for guidance.
