Scan a loyalty card, name it, show it at the till. That's the whole app.
No account. No cloud. No ads. No tracking.
Your cards are stored on your iPhone and never sent anywhere. There is no server to leak them, because there is no server.
No offers feed, no partner deals, no newsletter, no loyalty points dashboard, no notifications. It holds your cards and shows them. That is the entire product.
Free for 14 days. After that a single payment unlocks adding more cards — no subscription, and it never renews. Cards you have already saved keep working whether you buy it or not.
The unlock is shared with your Family Sharing group.
