The store gets your order. It doesn't need to keep your real email, your personal phone number, and a card that works everywhere, forever.
Merchant databases are the classic source of card fraud, and you can't control how a shop stores what you typed.
A single order enrolls your real email in newsletters, "partners", and eventually breach dumps.
That aliexpress-adjacent store with the great price? It gets the same real identity your bank has.
One Quackr ID identity per shop: alias email, private number, and a virtual card with a spend limit you set.
A $40/month limit means a compromised or unscrupulous merchant hits a wall: no surprise renewals, no drained account.
Rotate the alias, freeze the card. Your real inbox, number and bank card were never in their database.
Yes. They're real prepaid cards on the Visa/Mastercard networks. Fund the wallet, set limits per card, and use them anywhere cards are accepted online.
Aliases receive all mail, forwarded to your real inbox, and your private number receives real SMS, order updates and verification codes included. The store can reach you; it just can't identify or spam the real you.
