404 MONEY
把找不到的錢，找回來給你 Find the money you couldn’t see
回饋怎麼算、卡怎麼挑、錢散落在哪——先看清楚，再決定下一步。 How rewards add up, which card to use, where cash sits — see it clearly, then decide.

算得準、追得到、看得清——少漏賺一點。 Accurate estimates, cap tracking, and a clear net worth view.

回饋計算Reward estimates
花多少、在哪花，立刻知道比較划算刷哪張——數字跟銀行規則對齊。加碼還剩多少、這個月刷滿了沒，一眼看懂，少漏賺。See which card fits a spend — numbers aligned to bank rules. Remaining boosts and monthly caps at a glance.
為什麼可信 Why it’s trustworthy
FinTech 工具最怕資料外流。404 的記帳明細預設留在你的手機；不上傳完整帳本、不要求註冊帳號。 FinTech tools shouldn’t leak your ledger. 404 keeps expense data on your phone by default — no full-ledger upload, no required account.
