A log, not a bank connection
CardWarden does not link to your bank and does not move money. You log credit card transactions yourself: what you spent, and what you paid. The card number stays in the same encrypted vault as your loyalty and gift cards.
Due dates
Set the payment due day and CardWarden can remind you before that date. The reminder is only as useful as the date you entered. It does not pull a due date from the issuer.
Statement balance
Set the statement day. After each statement date, CardWarden calculates the statement balance from the transactions you logged. That number matches the issuer only if every transaction in the period is in the log. A purchase you forgot to add will not appear, and the balance will be short by that amount.
