Stopp Corona (Austria)

While Germany saw the light very early on in aligning itself with the Apple-Google initiative, Austria didn’t need any convincing at all. It was actually one of the first European nations to get on board with Apple’s approach with its Stopp Corona app.

Since it uses Apple’s Exposure Notification, this means that it’s Bluetooth based and decentralized, so no data is actually stored outside of the user’s iPhone, and the entire thing is voluntary at every stage of the process, even to the point of a COVID-19 positive person choosing to share their diagnosis.
