+# BezahlBrudi
+
+In an effort to reduce the usage of Paypal, I created this simple web app. It can generate GiroCodes that can be used to easily transfer money between friends by showing a QR code that can be scanned by most banking apps. It will import all neccessary infos for a normal SEPA bank transfer. No third parties involved, only the banks of the friends who want to exchange money.
+
+# How to use
+
+Simple visit the webpage, and put in the details. The QR code will be generated automatically. You can choose to save your details in a cookie, so you don't have to input your bank details everytime. The cookie will be store on your device.
+
+# Data privacy
+
+The web app doesn't store any data of the sender, the receiver or the transaction. Everything runs locally in your browser.
+
+# Notes
