The internet never forgets. Everyone has heard that before. But what does that really mean? In this talk, Dennis Schulz and Gregor Ziegltrum will show the chaos, the biggest insights, and the weirdest details that come back when someone invokes their European right of access to their own personal data.

Dennis, Gregor, and their team asked hundreds of companies for their personal data: online shops, social networks, advertisers, health insurers, dating platforms, and many more. They received everything from manually redacted PDFs to gigabytes of CSV and JSON files and tried to reconstruct their online and offline lives. They turned to AI to handle the heaps of data, and before they knew it, it had assembled an almost complete biography of them.

In this talk, Dennis Schulz and Gregor Ziegltrum will unpack all the datasets they received: small online shops, medium-sized tech companies, and the Silicon Valley giants. Using this data, they will try to analyze their own behavior: Have they truly never ghosted anyone while dating online? Can they tell where they went on vacation ten years ago? And do they even want to know what their search history reveals? In true “what could go wrong?” spirit, Dennis and Gregor will run a live demo on their own data. The audience will face the most embarrassing things companies already know about people!
