  Mobile applications and online service providers track our virtual and
physical behaviour more actively and with a broader scope than ever before.
This has given rise to growing concerns about ethical personal data management.
Even though regulation and awareness around data ethics are increasing,
end-users are seldom engaged when defining and designing what a future with
ethical personal data management should look like. We explore a participatory
process that uses design futures, the Future workshop method and design
fictions to envision ethical personal data management with end-users and
designers. To engage participants effectively, we needed to bridge their
differential expertise and make the abstract concepts of data and ethics
tangible. By concretely presenting personal data management and control as
fictitious entities called Data Daemons, we created a shared understanding of
these abstract concepts, and empowered non-expert end-users and designers to
become actively engaged in the design process.
