No. We don't share your personal information (your name, your email address, your credit card) with anyone, including the businesses you shop with, without your explicit permission.
We neither store, nor see your credit card information. We integrate directly with Visa, MasterCard, etc (who already have your card information). When you register your card with the app, your card number is encrypted and sent directly from your phone to Visa, MasterCard, etc. They mark your card as "enrolled" and send us a notification when you use it to make a purchase at a participating location.
