Willingness to install the contact tracing "Luca app" in Germany 2021

Almost 41 percent of Germans already installed or would voluntarily install the Luca app, Germany's contract tracing app, on their smartphones. The app is a part of German measures to trace those exposed to confirmed coronavirus (COVID-19) cases, as lockdowns are gradually eased nationwide, therefore leading to more activity among the population. Users input their personal and contact information into the app after installation and generate a personal QR code. This QR code may subsequently be scanned wherever required, for example in a restaurant or shop (provided that the establishment cooperates with the Luca app), instead of information being filled in individually at different locations. The legal framework allows local health authorities to access the data in the event of an infection and therefore inform those who need to undergo testing and quarantine due to the exposure. The app may also be used privately among family and friends as a calendar to record previous contacts and meetings in the event of a coronavirus (COVID-19) infection.
