Card Nest

Card Nest is a private, offline-first organizer for credit cards, spending, bills, budgets, and payment reminders.

Keep card details and financial activity together without creating an account or connecting a bank. Card Nest stores your records locally and gives you practical tools to understand spending and stay ahead of upcoming obligations.

Organize Your Cards

• Track card networks, limits, statement dates, due dates, expiry, and annual fees
• Add benefit notes and important issuer links
• Group related cards that share an account or limit
• Store optional full card numbers and CVVs with local encryption
• Keep sensitive values hidden until you deliberately reveal them

Track Spending and Payments

• Record purchases, payments, refunds, cashback, fees, interest, and credits
• Organize transactions using custom categories
• Track cash, bank or UPI, meal-card, and credit-card sources
• Add notes, tax details, monthly repeats, and receipt images
• Review card balances, payment activity, and statement cycles

Plan Budgets and Commitments

• Set income and overall budgets for flexible monthly cycles
• Add category spending limits
• Track loans, external EMIs, and card purchase installments
• Review savings, remaining funds, and spending patterns

Reports and Reminders

Explore clear charts and reports by period, category, and payment source. Export masked transaction reports as CSV or PDF. On Android, enable optional reminders for payment due dates, annual fees, and card expiry.

Backup and Security

Create an encrypted .cnbak backup protected by a separate passphrase and restore it when needed. Add an optional application PIN and use Android biometric unlock on supported devices.

Private by Design

Card Nest has no account, bank connection, advertisements, analytics, trackers, or developer cloud. Core card, transaction, budget, calculation, and reporting features work locally on your device.

Card Nest is a personal tracking tool, not a banking or payment service. Always verify balances and due dates with your card issuer.
