這是一個個人自用的小工具：每月底整理自己各張信用卡與貸款應繳的金額，算出要從自己帳戶轉出多少錢。不對外開放，也沒有其他使用者。
工具會以唯讀方式讀取擁有者本人 Gmail 裡的銀行帳單通知信，只用來取出應繳金額與繳款截止日。
A personal, single-user tool that totals the owner's own monthly credit card and loan payments. It reads the owner's own bank statement emails from Gmail with read-only access. It is not offered to anyone else.
