The Robert Koch Institute (RKI) as the national public health institute publishes the Corona-Warn-App on behalf of the German Federal Government for Germany. The app serves as a digital complement to distancing, hygiene, and wearing masks. It uses Bluetooth technology and the Apple/Google Exposure Notification APIs. The app is designed to help break infection chains by informing you if you were recently close to someone who subsequently tested positive for COVID-19. However, at no time does it collect any personal information. Who you are and where you remain secret – and your privacy is well-protected.
