5. Storage, Security & Offline Architecture

Munim Book is built with an offline-first design:

  • Local Sandboxing: Your billing data is stored locally on your device within Android's protected app-private directory (SQLite / Room database), inaccessible to unauthorized third-party apps.
  • Encryption in Transit: When synchronizing with WebCultivation cloud servers, all network traffic is secured using industry-standard Transport Layer Security (TLS 1.3 / HTTPS).
  • Cloud Storage Encryption: Cloud backup snapshots are encrypted at rest using AES-256 standard encryption on ISO-certified data center infrastructure.

6. Third-Party Integrations & Tools

Munim Book integrates with trusted industry SDKs to provide critical infrastructure:

  • Google Play Services: For application distribution, license validation, in-app billing, and automatic app updates.
  • Firebase (Google LLC): Used exclusively for crash reporting (Crashlytics) and anonymized application performance metrics to resolve bugs.
  • WhatsApp / Messaging Intents: When you share an invoice via WhatsApp, Munim Book triggers an Android system intent passing the PDF to the official WhatsApp app installed on your phone. We do not access your private WhatsApp conversations.
  • UPI Payment Apps: Standard NPCI UPI URI intents are generated on-device. Munim Book does not handle, store, or process your bank PINs, OTPs, or debit card credentials.
