FAQ

Good questions.

Does it work outside the US?+

Yes. Choose the UK or Other country preset, set your own tax-year start (e.g. April 6), use kilometres, rename the categories and pick from 27 currencies.

What mileage rate does it use?+

Whatever rate you enter in Settings. It starts at 0 so you set the rate that applies to you, and you can override it on individual trips.

Where are my receipts stored? Can you see them?+

Only in your browser on your device. Nothing is sent to me or anywhere else. Backups include your receipt images.

Does it work on my iPhone?+

Yes, use the hosted version. After you buy, open your private app link in Safari and tap Share, then Add to Home Screen. It opens full screen and works offline after the first visit. We test in Google Chrome, including phone-size screens. If anything doesn't work on your device, message us.
