Our research responds to calls for more engagement with everyday personal data. We used a co-designed, fictional persona called Alex Smith to concretise and represent people's online information to help participants (through role-playing) reflect on data and digital traces. Drawing together four fields of scholarly research concerning personal data: digital traces and the digital self, datafication and dataveillance, mundane, everyday data and the data journey – our aim was to advance understandings of personal data by exploring ordinary people's seemingly innocuous digital traces generated through everyday online interactions. Our paper presents three key findings from our analysis: (1) how ordinary people cope with and manage everyday data; (2) the haunting effects and affects of peer-to-peer surveillance and (3) postdigital identities. We argue that greater attention needs to be paid to everyday digital traces – how they are understood, managed and revealed because this has implications for ordinary people, corporate entities and governments. We contribute to a gap in critical data studies literature that calls for further investigations into ordinary people's engagement with data. We also offer a method that can be adapted for and used with different participant groups, which also supports their awareness of cumulative functions of personal data and potential use by un/known actors.

This paper argues that trust cannot be taken for granted in long-term participatory research and promotes greater consideration to conceptualizing the trusting process as fluid and fragile. This awareness by researchers can reveal to them how the passing of time shapes and reshapes the nature of trusting relationships and their constant negotiation and re-negotiation. The paper draws together literature from different disciplines on the themes of trust, temporality and participatory research and outcomes from interviews and workshops undertaken for The Trust Map project to focus on two key moments that reveal the fragility of trust. These are the subtlety of disruption and trust on trial and trust at a distance. We discuss how trust was built over time through processes of interaction that were continually tested, incremental and participatory.
