“In principle, the concept of a « Corona App » involves an enormous risk due to the contact and health data that may be collected. At the same time, there is a chance for « privacy-by-design » concepts and technologies that have been developed by the crypto and privacy community over the last decades. With the help of these technologies, it is possible to unfold the epidemilogical potential of contact tracing without creating a privacy disaster.

We however advise against the use of apps that do not meet these requirements.”
