I just placed an order with an online retailer I hadn't used before and got sucked into Shop Pay before I realized what was happening. ALL of my contact and credit card info appeared and I didn't know how they got it. I have never even heard of Shopify before this experience and do not have an account, so cannot log in and deactivate it.Was seriously creeped out and have spent over an hour this morning trying to find out what Shop Pay is, how it got my info and how to delete it. I finally found a link on a social media site and used it to stop Shop Pay from butting into future transactions and storing my info.As a customer to any online business considering Shopify: If I ever see this option again I will immediately abort any purchase. Apparently if you offer it as a checkout option and I do not opt out at that time, my info is collected and used for any future business that has Shopify. I don't know the legalities, but personally I consider this fraudulent.
