SaoPiao Support
Last updated：October 8, 2026
SaoPiao scans QR codes on Taiwan e-invoices in batches, removes duplicates, and exports CSV or Excel (XLSX) files. For questions or feedback, email anderson.hu@amperestudio.com with your iPhone model, iOS version, and App version. Invoice data stays on your device; only the seller's tax ID is sent when looking up store names (can be turned off in Settings). See the Privacy Policy.
