I asked Tinder for my data. It sent me 800 pages of my deepest, darkest secrets

The dating app knows me better than I do, but these reams of intimate information are just the tip of the iceberg. What if my data is hacked - or sold?

At 9.24pm (and one second) on the night of Wednesday 18 December 2013, from the second arrondissement of Paris, I wrote "Hello!" to my first ever Tinder match. Since that day I've fired up the app 920 times and matched with 870 different people. I recall a few of them very well: the ones who either became lovers, friends or terrible first dates. I've forgotten all the others. But Tinder has not.

The dating app has 800 pages of information on me, and probably on you too if you are also one of its 50 million users. In March I asked Tinder to grant me access to my personal data. Every European citizen is allowed to do so under EU data protection law, yet very few actually do, according to Tinder.
