Encrypted Credit Card Manager

Credit Card Manager & Reminder is a 100% offline app that helps you organize your credit cards, track statement dates, manage bills and subscriptions, and monitor your spending—all while keeping your data completely offline. Your financial information never leaves your device.

💳 CREDIT CARD VAULT
• Store your card details securely: Card number, Expiry date (optional), CVV (optional), Cardholder name (optional), Card network, and Card Limit.
• On-Device Encryption: Your sensitive card details (card number and CVV) are individually encrypted on-disk using AES-256-GCM, with keys securely derived from your custom App Lock PIN.
• Scan cards with your camera to quickly auto-fill details using on-device text recognition.
• Assign card categories (Credit, Debit, Prepaid, Charge) and tiers (Classic, Gold, Platinum, etc.).
• Keep eyes off your screen with privacy toggles to mask card numbers on your main list.

🔒 PRIVACY BY DESIGN
• Works 100% offline. No servers, no trackers, and no analytics.
• Secure vault locked by your device's biometric sensor (fingerprint/Face ID) or custom PIN.
• Transfer your data securely between your own devices via QR code—we never see your data.

📊 EXPENSE, SUBSCRIPTION & EVENT TRACKER
• Expense Tracker: Log daily spending, track categories, and view analytics charts and monthly trends.
• Subscription Tracker: Never get billed by surprise. Track recurring subscriptions and renewal intervals.
• Event Budgets: Group credit card charges into custom Events (e.g., travel, holiday shopping) to track group spending.
• Installments: Track installment plans (e.g. Installment 3 of 12) and view remaining balances.

📅 IN-APP BILL CALENDAR
• View statement cycles, subscription renewals, payment due dates, and expense events on an interactive, color-coded calendar.
• Schedule offline local notifications to remind you before statement cycles and bills are due.
