In this study, the German "Corona-Warn-App" of the German Federal Government and the Robert-Koch-Institute is examined by means of a non-representative online survey with 1482 participants for reasons of use and non-use. The study provides insights into user behavior with the app during the Corona pandemic, highlights the topic of data protection and how the app is used in general. Our results show that the app is often not used due to privacy concerns, but that there are also technical problems and doubts about its usefulness. In addition, the app is mainly used due to altruistic reasons and is often opened to view the own risk assessment and to ensure its functionality. To better understand the results, we compare our results with a sample of infas 360 with 10553 participants. It is shown that the results of this study can be compared to a larger population. Finally, the results are discussed and recommendations for action are derived.

电晕警告应用程序：Erste Ergebnisse einer Onlineumfrage zur（Nicht-）Nutzung和Gebrauch

在这项研究中，德国联邦政府和罗伯特·科赫研究所的德国“ Corona-Warn-App”通过使用1482名参与者的非代表性在线调查进行了研究，以了解其使用和不使用的原因。该研究提供了在电晕大流行期间应用程序用户行为的见解，重点介绍了数据保护的主题以及应用程序的总体使用方式。我们的结果表明，出于隐私方面的考虑，该应用通常不被使用，但同时也存在技术问题和对其实用性的怀疑。此外，该应用程序主要是出于无私的原因而使用，并经常打开以查看自己的风险评估并确保其功能。为了更好地理解结果，我们将我们的结果与具有10553名参与者的Infas 360样本进行了比较。结果表明，这项研究的结果可以与更大的人群进行比较。最后，讨论了结果并提出了行动建议。
