What do you reveal about yourself ?: Corono warning app in check

The federal government’s Corona Warning app had a brilliant start. According to the RKI, it was downloaded almost eight million times after two days. The app should make it easier to track corona infections. To this end, Bluetooth is used to check whether two smartphone owners are at a distance of two meters or less from one another for 15 minutes or more. The special feature of the app: If a user tests positive and then stores this information in the app, all people who have been close to the person receive a notification. If you receive a corresponding notification via the app, you can have yourself tested at the till, even if you do not yet show any symptoms.
