Privacy Policy

Last updated: November 1, 2026

Welcome to HisabFlow, developed by FARHAD VARIETY STORE. HisabFlow is a personal and household bookkeeping utility designed to log income and expenses, organize category-based monthly budgets, track personal savings goals, and maintain informal debt/lending records. We are deeply committed to protecting your personal and financial privacy. This Privacy Policy transparently explains how your data is handled, how third-party advertising services operate, and your rights of control.

1. Developer & Business Identity

2. No Personal Data Collected by Developer

HisabFlow does not collect or transmit any personal or sensitive user data to the developer. We do not require, ask for, or transmit your real name, email address, phone number, GPS location, contacts, or bank account credentials. No user account registration or cloud sign-in is required to use the app.

3. On-Device Financial Storage

All financial records you enter—including income, expenses, monthly budgets, savings goals, debt/lending ledgers, account balances, and application settings—are stored strictly on your local device (in private Android SQLite Room database and SharedPreferences files). All bookkeeping entries you input remain exclusively on your physical device. FARHAD VARIETY STORE operates no centralized database storing your personal accounts and cannot view, monitor, or access your records. None of your financial records are ever uploaded to any developer server or cloud storage.

4. Data Security & PIN Protection

To safeguard your records against unauthorized physical access, the app provides a 4-digit PIN lock. Your PIN is stored and verified strictly on-device using cryptographic salting (PBKDF2/SHA-256); the plain PIN is never stored. Repeated failed PIN entries trigger an escalating temporary lockout. All app data resides within Android's protected application sandbox.

5. Third-Party Advertising (Google AdMob & UMP)

To keep HisabFlow free to use, we display advertisements via Google AdMob (Banner, Native, Interstitial, and optional Rewarded formats). For ad serving, fraud prevention, and analytics, Google AdMob uses internet connectivity and may process pseudonymous telemetry such as the Android Advertising ID (AD_ID), IP address, and technical device parameters. For users in the European Economic Area (EEA) and UK, Google User Messaging Platform (UMP) manages regulatory consent.

6. User Controls & Advertising ID Opt-Out

You retain full control over advertising identifiers. At any time, you can navigate to your device settings (typically 'Settings > Google > Ads' or 'Settings > Privacy > Ads') and select 'Reset advertising ID' or 'Delete advertising ID' to limit personalized ads.

7. Android Permissions Used

  • • INTERNET: Required by Google AdMob to fetch ad creatives over the network.
  • • ACCESS_NETWORK_STATE: Allows checking active internet connectivity before attempting ad requests.
  • • com.google.android.gms.permission.AD_ID: Standard Google Play Services advertising permission on Android 13+.

8. Data Retention & Deletion

Because all financial data is stored purely on your device, you have total retention control:

  • 1. Tap 'Reset Financial Data' in Settings to permanently wipe all local transactions, budgets, goals, and accounts.
  • 2. Uninstalling HisabFlow or clearing application storage in Android Settings permanently removes all records. No residual data exists on any remote server.

Because all records reside solely on your device with no remote cloud backup:

  • • If you forget your security PIN,
  • • If your device is lost, stolen, formatted, or damaged,
  • • If you uninstall the app or clear its application data,

FARHAD VARIETY STORE has no technical capability to recover or restore your financial data. Maintaining independent backups of critical figures is entirely your responsibility.

9. Cloud Backup Status

HisabFlow explicitly configures 'android:allowBackup=false' in its AndroidManifest.xml. The app does not automatically upload database backups to Google Drive or external cloud services.

10. Children's Privacy

HisabFlow is not directed at children under the age of 13. We do not knowingly solicit or collect personal information from children under 13.

11. External Links

The application provides external intents to rate on Google Play, share via the system share sheet, and launch your email client for support. Interacting with third-party advertisements directs you to external properties subject to those third parties' respective terms. When using these services, the respective external platform policies apply.

12. Policy Changes

We may update this Privacy Policy from time to time. Any revisions will be published within the app and on this page with a revised 'Last updated' date.
