COMMON QUESTIONS

Frequently Asked Questions

Do you accept payments in Indian Currency (₹ / INR)?

Yes, absolutely. We are based in Kolkata, India, and support all standard Indian payment methods including UPI, Net Banking (NEFT/RTGS/IMPS), Debit/Credit Cards via Verified Payment Gateways, and GST-compliant invoices.

How do you build apps using Flutter and Android Studio 4?

For cross-platform apps needing quick time-to-market on both iOS and Android, we utilize Google Flutter with Dart. For specialized Android applications requiring deep on-device hardware access, local PDF parsing, or background alarms (like our Statement Analyzer and Legal Diary), we engineer natively in Android Studio 4+ using modern Kotlin and Jetpack Compose.

What is covered under 24/7 Cloud & Firebase Server Maintenance?

Our 24/7 cloud custody includes active server health telemetry, Linux OS security updates, automated database backups, Firebase Firestore performance tuning, security rules auditing, SSL certificate renewals, and an emergency response SLA where our engineers triage critical incidents within 15 minutes.

Can I choose a demo website and have it customized for my brand?

Yes! When you submit a project request, our engineering team tailors a proven, high-performance architecture to your brand colors, logo, product catalog, payment gateway, and domain within 5 to 7 business days.
