COMMON QUESTIONS

Frequently Asked Questions

Answers to common questions about developing custom finance, payment, and FinTech applications.

How do you protect sensitive user financial data in the app? +

We implement end-to-end cryptographic protocols including hardware-backed biometric authentication (FaceID/BiometricPrompt), AES-256 database storage encryption, TLS 1.3 network transit, and SSL certificate pinning to prevent interception.

Can the app integrate with payment gateways and UPI? +

Yes. We integrate verified payment gateways like Razorpay, Stripe, and PayPal, as well as native UPI deep-linking that opens banking apps securely for instant fund transfers.

Can you build automated loan EMI calculators and repayment tracking? +

Yes. We build dynamic financial calculators for principal, interest amortization schedules, pre-closure models, and automated push notifications for upcoming repayment deadlines.

How do you prevent duplicate charges during slow network conditions? +

We engineer idempotent transaction APIs with unique request tokens. Even if a user clicks submit multiple times during poor connectivity, the server processes only one charge safely.

How long does finance app development typically take? +

A focused personal finance, expense tracking, or loan calculator MVP app takes 7 to 9 weeks. Comprehensive multi-rail payment ecosystems or digital banking apps generally take 12 to 16 weeks.
