Questions

Do I need an account?

No. Open the app and start. Your logbook lives in your browser on your device.

Where are my receipt photos stored?

Only on your device, inside your browser. They are shrunk to save space and never uploaded. Pro backups include them.

How do I install it on my phone?

Open the app, then choose "Add to Home Screen" (iPhone: the Share menu in Safari; Android: the browser menu).

Can I move my data to a new phone?

Yes. Settings → Download backup, then Restore backup on the new device.

Is Pro a subscription?

No. One payment and you get a key that unlocks Pro on your devices. 14-day refund if it is not for you.

Does the mileage report work for taxes?

It adds up the business trips you enter and multiplies by a rate you choose. It is not tax advice; check the rules that apply to you.

Stay safe. Please don't use OilTag while driving; log your fill-up once you are parked. Reminders follow the intervals you set; always follow your vehicle maker's maintenance schedule.
