The expose of Cambridge Analytica revealed how little protection Facebook afforded our data and how democracy is undermined if it’s used illegally. However, people have also begun to realise just how much data these firms hold on us legally. Waterford web developer Dylan Curran downloaded his Google data and wrote about it in a Twitter thread that went viral. He said his file was roughly three million word documents.

He discovered that with indefinite range, Google stores your location, your emails, your search history, every YouTube video you’ve ever watched, what time you go to sleep, your photos, calendar appointments, who you’re in contact with, the files you download, the games you play, the apps you use, what you’re listening to and even documents and files you deleted years ago. His file was one decade-long digital footprint.
