I've never actually used a supermarket loyalty card connected to my real persona. Either the information has all been fake, or I've used somebody else's. At the end of the day, I use the same credit card every time I shop, so I'm sure that they can harvest all their data from that. But I feel like it's a bit of a "fuck you" to the system that my loyalty card says I'm a 40 year old woman.

They don't really care though. The point of a loyalty card is to connect all of your purchases to one person or household. Knowing the age and gender of that person is interesting, but not really necessary. These supermarkets want to know if there is a correlation between you buying X frequently, and Y occasionally. They want to know if your profile is that of a bargain hunter or a premium gourmet hobby chef. Knowing all that, they can offer you tailored deals designed to nudge your spending behaviour one way or another, and they can determine if a specific store location should focus more on certain groups of customers.
