Did she buy something there with a credit card? That data is commonly resold.

You are not plaids customers. They will be selling your transactions to everyone and anyone. It's pretty easy to identify people from their transactions.

Are there credit card companies which do not sell transaction data?

It doesn't say it leaks transaction history, the text says it will tell the bank if you have a long history of purchases.

I can't see how the /contents/ of those transations are leaked via this route, or even what remote stretch of reasoning would indicate it. No bank cares w
