Merchant name, MCC, card and reward outcome — the four things that make this database useful.
Search existing merchants, or type a new name exactly as it appears at checkout.
Type the four-digit code from your statement or SMS — the name resolves instantly.
Leave blank if you do not know the MCC yet.
Pick the bank first, then the exact card variant.
What actually landed, not what the T&C claims.
Outcome
Reward type
How you paid and when — recency is what makes this useful.
Payment context
Reports are append-only: nothing you add overwrites someone else's result. Conflicting outcomes are shown side by side.
