CardDue: Credit Card Tracker

A simple way to keep track of what you owe on your credit cards. In CardDue you add the cards and you enter the amounts. The app takes it from there: statement dates, due dates, remaining debt and everything you have paid so far. It does not access bank accounts, does not ask for online banking credentials and does not make payments for you — it keeps track, nothing else. WHAT YOU TRACK • Total card debt, the amount due this month and your total minimum payment on one screen • Statement day and due day per card, adapted automatically in shorter months • Full or partial payments; remaining debt is recalculated instantly • Payment history and how much of this period you have already paid • A reminder to update the balance when a new statement period starts — nothing you entered is wiped • Archive cards you no longer use instead of deleting them NEVER MISS A DUE DATE Reminders are scheduled 7, 3 and 1 day before the due date, plus one on the morning of the due date and an overdue notice if it passes. Notifications are scheduled on your device. With Pro you choose the days and the time per card. ONLY THE DETAILS THAT MATTER The full card number, expiry date and CVV are never requested. The app stores only what you type in: card name, bank name, card network (Visa/Mastercard), the last 4 digits, statement balance, minimum payment and credit limit. YOUR DATA STAYS ON YOUR DEVICE Your records live in a local database encrypted with AES-256, with the key held in the device's secure storage. No account, no sign-up, no e-mail required. Add a 4-digit PIN and biometric unlock if you want an extra layer. Your card and payment data is never sent to a server; network access is used only for store purchases and subscription checks. MULTI-CURRENCY 13 currencies: TRY, USD, EUR, GBP, CHF, AED, SAR, JPY, KRW, INR, BRL, CAD, AUD. There is no exchange rate conversion, so different currencies are never merged into one total — each is summed on its own line. STATISTICS Period debt, paid and remaining amounts, the overdue share, the remaining debt breakdown and a card-by-card view, all with charts. Pro unlocks the 6 and 12-month payment charts. 36 LANGUAGES AND THEMES The interface follows your phone's language by default and you can pick from 36 languages in settings, right-to-left languages included. Light and dark themes are both supported. FREE AND PRO Free: up to 2 active cards, basic reminders, this period's summary and the card-by-card breakdown. Pro: unlimited cards, JSON and CSV export, PIN and biometric app lock, per-card reminder settings, all 13 currencies, 6 and 12-month payment reports. The Free limit only applies when you add a new card. Cards you already have are never locked, hidden or deleted. CardDue is a tracking tool. It does not provide financial, credit or investment advice.
