This isn't a project developed for the public sector really. Afaik it's a privately funded, for profit, product that has been licensed by several states in Germany by now.

Apart from that the official (indeed publicly funded) Corona-Warn-App did a much better job at this. (They actually did follow all the recent best practices in software-develoment + it's (mostly) run as a free software project, taking community contributions seriously, reacting to feedback and issues, etc.)

Sounds like a contractor developing something that gets paid with public money.

Sure. It's made by SAP.
