Wow. Did not now this App will be open source (backend and front end!)!<p>I heard they wanted to really bring it to highest (possible) privacy level <i>without</i> a central "Master knows all" server. But open source is a real wow for a German governement project.<p>So, maybe one could adapt the title of this HN post "Germany’s Corona-Warn-App will be open sourced on GitHub"?
