Stop impulse buying, with no bank login.
Vauban tracks your spending from your bank's notifications and stops you at the right moment. Your data stays on your phone.
Why Vauban?
Automated Tracking: The app intelligently reads payment notifications from your bank and digital wallets to update your budgets, keeping this information strictly on your device. See supported banks
Anti-Impulsive Buying: Get real-time budget alerts right before opening a shopping app or your digital wallet.
Physical Friction (NFC): If you go over budget, Vauban requires you to disable your phone's contactless payment to instantly prevent impulsive in-store purchases.
On your computer too: The Vauban Guard browser extension blocks payment pages; the app only gives you the unlock code after a pause. The two only talk through QR codes.
100% Local-First: Your financial data (budgets, transactions, history) never leaves your phone. No Cloud account is required.
