We don't sell user data and we make money by taking a cut of the savings we're able to claim on behalf of our users. It aligns our incentives and keeps us focused on maximizing the savings our users get.

We started building Paribus when we realized that most retailers were actually using PII and user information to price discriminate and overcharge their customers. The last thing we want to do is help enable these practices.

We are not selling data. Our model is to charge a portion of refunds that we actually get for you (that way we share same incentive as our users)

If you read the article you'll notice that they take a 25% commission on the refund amount.
