About your receipt data.

A receipt is a document issued upon receipt of payment for services or goods. Receipts are also called vouchers and serve as proof of receipt of money. Vouchers cannot be disposed of at one's discretion because the retention period of vouchers is set by law. The retention period differs between regional regulations.
We do not set digital data storage periods now. We save your data as long as our service exists. Or unless requested by the issuer and receiver after the regulated period.
