Dataswift had a usability issue. This brilliant team of academic researchers had created a new way for consumers to own the data created when they interacted with services online, but the experience was confusing.
Starting at the sign-up process, I designed the UX flow to be compliant with daunting EU privacy regulations (but friendly enough that users would not be too intimidated.)
In the beginning, the platform was little more than a big data dump. There was not much utility for end-users. This changed with data filters that allowed users to organize and learn from the aggregated data they collected, stay notified of any issues via data audits, and maintain better control of how and where their personal data was shared.
In addition to the UX you see above, I also designed the UX for a developer portal for companies and their engineering teams to help with GDPR compliance and security through plug-and-play identity and authentication. (But that's another story.)
