Many governments have seen digital health technologies as promising tools to tackle the current COVID-19 pandemic. A much-talked example in this context involves the recent deluge of digital contact tracing apps (DCT) aimed at detecting Covid-19 exposure. In this short contribution we look at the bio-political justification of this phenomenon and reflect on whether DCT apps constitute, as it is often argued, a serious potential breach of our right to privacy. Despite praising efforts attempting to develop legal and ethical frameworks for DCT apps’ usage; we argue that such endeavours are not sufficient to tackle the more fundamental problem of mass surveillance, which will remain largely unaddressed unless we deal with the biopolitical arguments presented and resort to a technical and structural defence.
