Where do you shop? How big is your house? Do you give money to charity? Do you own a timeshare? Or a credit card? Have you bought a car recently? Are you in debt? In a new relationship? A new job?
The result has been a digital goldmine. In just three months this year, Facebook made £4.8billion from ad sales, because it could point advertisers to exactly the people they were after.
But how did Facebook get that data in the first place? For much of it, the answer is simple: because you told it.
