# 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 necessary 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 under [BezahlBrudi.jetzt](https://bezahlbrudi.jetzt), 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 every time.

# Data privacy

The web app doesn't store any data of the sender, the receiver or the transaction outside of your machine. Everything runs locally in your browser. The `RememberMe` function uses a cookie that expires after 180 days.
