Statistical analysis of the daily diagnosis keys of the official German COVID-19 tracing app (Corona-Warn-App). The daily dumps of the diagnosis keys are being analyzed with the diagnosis-keys-toolset by mh-. These data can only be estimated, due to the decentralized architecture of the tracing app. Hence, all information are without any guarantee. All diagrams in this repository are licensed under CC BY-NC-SA. See for more information about the COVID-19 tracing app for Germany. An alternative dashboard by janpf can be found at

Note: Since February 2021, exact statistical data are being published within the CWA, which are used by this page and make the estimation of data redundant.
