Most of the PDS’ choose not to disclose the number of users. They also all have functioning apps, however with varying degree of functionality (except Data for Good and Mydex, who seems to work through partners’ setups). These PDS’ all reports having raised between 4 and 10 mil. In between the mature and relatively immature PDS’ comes a middle category with Mydex, Polypoly, CitizenMe and Meeco. In the other end of the maturity spectrum comes with investments of more than 30 mil. Also all of these PDS’ have raised modest levels of investments - they disclose themselves, that the combined investments and grants are all below 2 mil. The PDS’ which stood out to us as least mature was Onecub and Schluss, who don’t yet have a functioning app and iGrant.io, OwnYourData and Ethi, whose apps seemed only very basic. When going through the results, what first stroke us, was how relatively small and immature most of the PDS’ seemed. Also the results from the survey are nearly all based on pure self-descriptions from the participating PDS’, which leaves a lot of leeway for misunderstandings or straight out false answers. The survey is, however, fra from perfect: Only 13 out of 28 identified PDS’ participated, and many more might exist. To the best of our knowledge, the survey represented the first publicly available overview of PDS solutions (see table 1). We’re building this analysis on the Personal Data Store Survey we conducted during the summer of 2021 (for full survey results, click here). Making great solutions today isn’t necessarily a guarantee the solution is also great tomorrow. But nevertheless we hope the basic analysis of the forces at play have helped illuminate the PDS’ playing field, and draw attention to principles, which at least we find to be decisive for the future development of our digital world.īut there’s an important aspect on which the PDS’ differ: Their ability to ensure users the privacy offered by the PDS will be respected not only now, but also in the future. Pernille is pro bono in the advisory board of both polypoly and Data for Good Foundation. Jon is an affiliated pro bono specialist with Data for Good Foundation, and during the research Jon was employed by polypoly Denmark. You might disagree with how we portray individual PDS’ and you most certainly should question how we treat the PDS’ (polypoly and Data for Good) with which we are personally involved. Others again on utilising data for valuable services to users.įull Disclosure: This analysis is written from our vantage points as professionals embedded in the space ourselves. Others on cryptography and on how to make secure computation possible. Some focus on storage of data, like extended cloud services. Naturally, not all Personal Data Stores (hereafter just “PDS’”) are the same. They comes with the promise of empowering the users to reclaim control of their digital lives. That’s our take on how to make sense of this vital part of our digital future.įuelled by big tech’s exploitation of user’s personal data, a new and hugely exiting breed of privacy-preserving technologies has emerged: Personal Data Stores. However, a sweet spot exists, where Personal Data Stores – the ones we are rooting for – are likely to be able to scale up without sacrificing their ideals. Some are challenged by their underlying business model, others by their organisational setup. But not all of them are likely to succeed in the privacy-preserving quest. Personal Data Stores are technologies which share the ambition of letting users remain in control of their own data. The market for Personal Data Stores is growing.
