Could you explain in plain language how this is different or the same as what a credit card company does?
My outsider understanding was that credit card companies happily sell your purchase history or at least aggregate it for marketing, in addition to using your purchase history model to predict if a purchase is fraudulent.
Stripe’s very readable privacy policy makes a clear statement on this:
Stripe does not sell or rent Personal Data to marketers or unaffiliated third parties. We share your Personal Data with trusted entities, as outlined below.
From that and my reading of the rest, I think the answer is clearly no. Also I doubt the data of consumer purchases on Stripe integrated websites is even that valuable to begin with. At least compared to Stripe’s margins.
