YOUR DATA
The database is encrypted on the device. Backups are encrypted with your password—even we couldn't open them. There is no account because there is no server on which one could reside.

Two functions can establish a connection—if you explicitly allow it: the renewal of a firm license and the location search in the logbook. Both are disabled by default, both explain in detail beforehand what data will be sent, and both continue to function without this permission.

FREE TRIAL
Five scans to try it out, one-time only. Everything else—logbook, journeys, export—can be used without limitations. Pro is available as a subscription or as a one-time purchase. If you work with a tax firm, they can also activate Pro directly for you.

NOTE
The app calculates and freezes the rates applicable to each receipt date. For trips outside of Austria and Germany, the app prompts for the daily rate instead of inventing one.

This is not tax advice. Information provided without guarantee.

What’s new

• Cash-register receipts (AT): scan the QR code first – date, total and VAT split come straight from the till, nothing to type
• The merchant is remembered per till and filled in on the next receipt automatically
• Receipts back to 2016 are valued at the rates in force at the time
• Receipts older than that are refused instead of loading forever
• Under "More details": till id, receipt number, certificate and signature status
