Effective Date: 27 July 2026 App: GSTBilling Pro Sandhya SoftTech Pvt. Ltd.

1. Introduction

Welcome to GSTBilling Pro ("we", "our", "us", "the App"), developed and maintained by Sandhya SoftTech Pvt. Ltd. ("the Company"). This Privacy Policy explains how we collect, use, store, and protect information when you use our Android application for GST billing, invoicing, and business management.

By downloading, installing, or using GSTBilling Pro, you agree to the collection and use of information in accordance with this Privacy Policy. We are committed to protecting your privacy and ensuring transparency about the data we handle.

  • Business information provided during registration and setup
  • Customer details entered by you for invoicing purposes
  • Product and inventory information
  • Invoice and GST billing records

3. Business Information

When you set up your business profile, we collect the following details to generate accurate GST invoices and reports:

Business Name

GSTIN and Email Address are optional fields — you can use core app features without providing them, though certain GST-compliant invoice formats may require a valid GSTIN.

4. Customer Information

GSTBilling Pro allows you to save your customers' details — such as name, contact number, address, and GSTIN — to generate invoices quickly. This information is entered and managed entirely by you (the business owner) and is used solely for billing and record-keeping within your business account.

5. Product Information

The App stores details of products and services you sell, including product name, description, price, HSN/SAC code, GST rate, and stock quantity. This data helps generate accurate, GST-compliant invoices and track inventory.

6. Invoice Information

Every invoice generated through the App — including invoice number, date, itemized billing details, tax breakdown, and payment status — is securely stored so you can retrieve, edit, print, or share it as a PDF at any time.

7. GST Billing Data

GST-specific data such as CGST, SGST, IGST calculations, tax slabs, and GSTIN details of both business and customers are processed within the App to help you remain GST-compliant. This data is used exclusively for invoice generation and reporting purposes and is not used for any unrelated purpose.

8. Authentication

GSTBilling Pro uses secure authentication methods to protect access to your business data:

Mobile Number Login
PIN Login

Your Mobile Number is used as the primary identifier for authentication, and your PIN adds an extra layer of security for quick, secure access to your account.

9. Firebase Usage

GSTBilling Pro uses Google Firebase, a secure cloud platform, to store and sync your business data reliably:

  • Firebase Realtime Database — securely stores business, customer, product, and invoice data in the cloud
  • Firebase Authentication (if enabled) — helps verify user identity securely
  • Firebase Cloud Messaging (if enabled) — used to deliver app notifications and updates

Firebase is operated by Google LLC and complies with industry-standard security practices. Your data transmitted to Firebase is encrypted in transit.

10. How We Use Your Information

  • To create and manage your business profile
  • To generate GST-compliant invoices and bills
  • To authenticate and secure your account
  • To sync your data securely across sessions
  • To provide customer support and resolve issues
  • To improve app performance and reliability

11. Data Storage

Your data is stored securely on Firebase Realtime Database (Google Cloud infrastructure) and, where applicable, locally on your device for offline access. We do not store your data on unsecured or third-party servers outside of Google's trusted infrastructure.

12. Data Security

We implement industry-standard technical and organizational measures to protect your information from unauthorized access, alteration, disclosure, or destruction, including encrypted data transmission, secure Firebase access rules, and restricted internal access.

Security Notice

All data transmitted between the App and Firebase is encrypted using industry-standard protocols (HTTPS/TLS). Access to your business data is restricted to your authenticated account only.

13. Data Sharing

We do not sell, rent, or trade your personal or business information to any third party. Your data is used solely to provide and improve the App's services. We may share limited data only with:

  • Google Firebase — for secure cloud storage and authentication

  • Google Play Services — core Android functionality

These providers have their own privacy policies governing the use of your information, and we encourage you to review Google's Privacy Policy for additional details.
