The sharing economy platform (SEP) has evolved significantly since the 1990s, driven by advancements in digital technologies such as the Internet, cloud computing, and big data. Its rapid growth has introduced significant economic benefits and new business models. However, it has also raised critical concerns regarding data privacy and data security. These concerns are critical in the SEP, where large amounts of consumer data are collected, raising fears of misuse and cyber-related incidents. Such issues can deter consumers from using platform services. This study investigated how data privacy and data security concerns influence consumer trust within the SEP, focusing on Uber and Bolt within the transportation sector in South Africa. A survey research strategy was used to collect data through semi-structured interviews with 14 Uber or Bolt users. The data was analysed using thematic analysis using the constructs of the privacy calculus theory to classify the themes that emerged from the data. The study reveals significant data privacy concerns, including unauthorised use of personal information and unwanted communications, and data security concerns such as cyber incidents and policy and security deficiencies. These concerns have an impact on consumer trust and continued use of the platforms. The findings of this study will provide insights for platform providers on how to address consumer concerns and improve service offerings.
