There is growing interest in contact tracing apps (CT apps) for pandemic management. It is crucial to consider ethical requirements before, while, and after implementing such apps. In this paper, we illustrate the complexity and multiplicity of the ethical considerations by presenting an ethical framework for a responsible design and implementation of CT apps. Using this framework as a starting point, we briefly highlight the interconnection of social and political contexts, available measures of pandemic management, and a multi-layer assessment of CT apps. We will discuss some trade-offs that arise from this perspective. We then suggest that public trust is of major importance for population uptake of contact tracing apps. Hasty, ill-prepared or badly communicated implementations of CT apps will likely undermine public trust, and as such, risk impeding general effectiveness.

人们对用于流行病管理的接触者追踪应用程序（CT 应用程序）越来越感兴趣。在实施此类应用程序之前、期间和之后考虑道德要求至关重要。在本文中，我们通过提出负责任的设计和实施 CT 应用程序的道德框架来说明道德考虑的复杂性和多样性。以此框架为起点，我们简要强调了社会和政治背景的相互联系、流行病管理的可用措施以及 CT 应用程序的多层评估。我们将讨论从这个角度产生的一些权衡。然后我们建议公众信任对于人们使用接触者追踪应用程序至关重要。仓促、准备不足或沟通不畅的 CT 应用程序实施可能会损害公众的信任，因此存在阻碍总体有效性的风险。
