The Robert Koch Institute (RKI) – in its capacity as the central federal institution for public health and as the German national public health institute – publishes the Corona-Warn-App on behalf of the German government The app serves as a digital complement to distancing, hygiene and wearing masks.
• No third-party access: Neither the person reporting a proven corona infection, nor those who have been notified can be traced – not by the German government, the Robert Koch Institute, any other user, nor by Apple.
• No personal information is transmitted: When you encounter another person using the app, your smartphones only exchange random IDs.
If a person is diagnosed with corona and chooses to share his/her own smartphone’s random IDs, all persons previously encountered will then be notified anonymously.
Based on maximum corona incubation times, the random IDs your smartphone collects are stored in an exposure log for 14 days and then deleted.
Corona-Warn-App is the main corona app for Germany, where it is interconnected with the national health care system.
The Corona-Warn-App does not collect any information about the location of the encounter or that of its users.
They measure the time and distance of an encounter, but do not allow to identify persons or find out locations.
When enabled, smartphones exchange encrypted random IDs with other devices using Bluetooth.
The random IDs only provide information about the duration and distance of an encounter.
Important: Information about the notified persons is not accessible at any time.
The app is designed to help break infection chains by informing you if you were recently close to someone who subsequently tested positive for corona.
However, at no time does it collect any personal information.
In addition to the exposure notifications, affected users will receive clear recommendations for action.
