The so-called Right to Data Portability (RtDP) promises to significantly reduce switching costs for consumers in digital service markets, provided that its potential is effectively translated into reality. Thus, of all the consumer rights in the GDPR, the RtDP has the potential to be the one with the most significant implications for digital markets and privacy. However, our research shows that the RtDP is barely known among consumers and can currently only be implemented in a fragmented manner—especially with regard to the direct transfer of data between online service providers. We discuss several ways to improve the implementation of this right in the present article.Text/Journal Article10.1007/s00287-021-01372-w1432-122X
