So there are two issues I was talking about: 1) rotation of tokens/virtual card numbers 2) giving the transaction data to merchants From what you copied here it seems that Google is rotating the virtual numbers - however, there's no way of knowing if Google isn't still tracking all of those numbers through your account and linking them back together for data mining. I think there's a high probability Google is doing that. Google only says it's rotating the numbers. And that leads us to #2, which remains completely unanswered. Google says it doesn't give the credit card information to merchants (as in your real credit card number). However it could still give the transaction data.
