Introduction

Last Updated: August 2026

This Privacy Policy explains how Hisab Book ("we", "us", or "our") handles your information when you use our mobile application ("App"). We are committed to protecting your privacy and ensuring your financial data remains completely under your control.

1. Data Collection and Storage

Local Storage: Hisab Book operates on a strict "local-first" architecture. All your personal data, customer details, transactions, and financial records are stored securely in a local database (SQLite) directly on your physical device. We do not collect, read, or transmit your financial data to our servers.

Analytics: We may collect non-personally identifiable crash reports and usage statistics to improve app stability and performance.

2. Third-Party Services

The App uses third-party services that may collect information used to identify you. By using the App, you agree to the privacy practices of these third-party service providers:

  • Google Play Services: Used for core application functionality and security.
  • Google AdMob: We use AdMob to display advertisements within the App to keep it free. AdMob may use advertising identifiers to serve personalized ads based on your interests. You can opt out of personalized advertising by visiting your Google Ad Settings.

3. Permissions

Our App requires specific permissions to function correctly. We only request permissions necessary for core features:

  • Storage/File Access: Required to generate PDF reports of your transactions and to facilitate local database backups and restores.
  • Internet Access: Required to sync backups to your Google Drive and to serve advertisements via AdMob.

4. Google API Services

If you choose to use the automated backup feature, Hisab Book will request access to your Google Drive via Google API Services.

Hisab Book's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Your backup data is uploaded exclusively to a hidden app data folder in your personal Google Drive. We do not process, read, or share your backup files with any third parties.

5. Data Deletion

Because Hisab Book is an offline application, you have complete control over your data deletion at all times. We do not hold your data on any central server.

To permanently delete your data:

  • Local Data: Simply uninstall the app, or clear the app data via your Android Settings > Apps > Hisab Book > Storage > Clear Data.
  • Cloud Backups: Open your Google Drive app, go to Settings > Manage Backup, and delete the backup associated with Hisab Book.

6. Data Security

We value your trust. Since the data resides exclusively on your device, the security of your information primarily depends on the physical and digital security of your device. We highly recommend using a screen lock, PIN, or biometric authentication to secure your phone, and utilizing Hisab Book's built-in App PIN Lock feature.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We advise you to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page.
