Privacy Policy — Smart Cash Book

Last updated: 22/07/2026

This Privacy Policy explains how Smart Cash Book (“the App,” “we,” “us,” “our”), developed by Nilay Mehta, collects, uses, discloses, and protects your information.

1. Information We Collect

  • Cash Book Data: All entries you create (income, expenses, categories, notes) are stored locally on your device using Room database and EncryptedSharedPreferences. This data is not uploaded to our servers.
  • Subscription & Purchase Data: If you subscribe to a paid plan, RevenueCat collects your purchase history, subscription status, and a device/account identifier to validate your plan.
  • PIN/Admin Panel: Your admin panel PIN is stored locally and encrypted on your device; we never receive or store it.

We do not collect: your phone number, home address, GPS location, contacts/phonebook, or camera access — unless you use optional reminder features (below), which use your device’s own SMS/WhatsApp/Email apps and do not send data to us.

2. Permissions We Request

  • SMS — only if you enable SMS reminders; messages are sent directly from your device, we do not access your message history
  • Storage — required to generate and save PDF exports of your cash book
  • Internet/Network access — required only for subscription validation via RevenueCat

3. How We Use Your Information

  • To let you track and export your cash book data locally
  • To validate and manage your subscription plan
  • To send optional reminders via WhatsApp, SMS, or Email at your request (using your device’s own apps)

4. Advertising & Payments

Smart Cash Book does not show third-party ads. The App offers paid subscription plans, processed via Google Play Billing and RevenueCat. We do not directly handle or store your payment card details — these are managed by Google Play.

5. Third-Party Services

We do not use reCAPTCHA, Google Analytics, remarketing services, or similar third-party tracking tools. We do not sell your personal information.

6. Data Storage & Security

Your cash book data is stored locally on your device using encrypted storage. Subscription data is stored by RevenueCat and Google Play on their secure servers.

7. International Data Transfers

Subscription data may be processed on servers outside your country of residence as part of RevenueCat’s and Google’s global infrastructure.

8. Data Retention & Deletion

Your cash book data is deleted immediately when you uninstall the app. To request deletion of subscription/billing records held by RevenueCat, contact mehta.nilay.b@gmail.com.

9. Children’s Privacy (COPPA)

Smart Cash Book is not directed at children under 13, and we do not knowingly collect information from anyone under 13.

10. Your Rights Under GDPR

If you are in the European Economic Area, you have the right to access, correct, delete, or restrict processing of your personal data, and to data portability. Contact mehta.nilay.b@gmail.com to exercise these rights.

11. Your Rights Under CCPA/CPRA (California Residents)

California residents have the right to know what personal information is collected, request deletion, and opt out of sale/sharing of personal data. We do not sell or share your personal information. Contact mehta.nilay.b@gmail.com.

12. CalOPPA Compliance

We do not respond to “Do Not Track” browser signals at this time, and we do not knowingly allow third parties to collect personal information about your activity over time across the App.
