Privacy Policy for Daily Cashbook

1. Overview & Introduction

Welcome to Daily Cashbook, a digital ledger and financial bookkeeping utility application developed and published by Emperor Smart Solutions ("we", "us", "our", or "Company"). This Privacy Policy explains our commitment to preserving your privacy, detailing how information is handled when you download, install, and use our mobile application across Android and supported platforms.

We respect your fundamental right to financial privacy. Daily Cashbook has been architected from the ground up as an offline-first local application, ensuring your private financial transactions remain strictly in your hands.

2. Information Collection & Usage

To provide context on how Daily Cashbook operates, here is an explicit breakdown of the data types processed by the application:

1. Financial & Ledger Data (Locally Stored):

   Any records you input—such as income values, expense amounts, payment methods, transaction dates, categories, remark notes, and custom ledger tags—are stored exclusively in an embedded local SQLite database managed by the app. This information is processed solely to calculate balances, generate cash flow charts, and render PDF/CSV reports.

2. Device & Performance Telemetry (Non-Personal):

   We may process standard non-identifying device metrics via official operating system APIs (such as Google Play Services). This includes device hardware model, operating system version, screen resolution, app installation version, system language, crash diagnostic logs, and ANR (Application Not Responding) metrics. This telemetry is strictly used to troubleshoot crashes and improve application stability.

3. No Personal Identification (PII):

   Daily Cashbook does not require account creation, sign-in, mobile OTP verification, social login, or submission of personal identifying details like your legal name, home address, or government ID numbers.

3. 100% Offline Data Storage & Security

Your trust is paramount. Here is how we enforce maximum data protection for your financial records:

• Local Database Engine: Data is persisted using high-performance local SQLite storage (Drift database engine).
• No Cloud Syncing: Daily Cashbook does not automatically sync your transaction history with external cloud databases, third-party storage, or remote servers.
• Biometric App Lock: The application supports device-level PIN, Pattern, and Biometric authentication (Fingerprint / Face Unlock). Biometric data is verified directly by your device hardware security chip (Android Keystore system) and is never accessible by Daily Cashbook or sent externally.

4. Device Permissions & Rationale

To deliver specific features, Daily Cashbook may request explicit runtime permissions. You maintain full control over these permissions via your device system settings:

5. Third-Party Services & Analytics

Daily Cashbook may incorporate reliable third-party Software Development Kits (SDKs) provided by industry leaders to maintain application quality and deliver in-app advertisements. These third-party services operate under their respective privacy policies:

• Google Play Services: Used for app distribution, core runtime services, and security checks.
  Google Privacy & Terms
• Google AdMob: Serves non-intrusive in-app advertisements. AdMob may utilize anonymous advertising identifiers (Advertising ID) to serve personalized or contextual ads according to user preferences.
  Google AdMob Privacy Policy

6. User Rights, Data Control & Deletion

Because Daily Cashbook stores all data locally on your smartphone, you hold 100% control over your data lifecycle:

• Data Export & Backup: You can export your entire transaction history to PDF or CSV files at any time through the app's Report section.
• Data Erasure: You can clear all cached transactions and reset your database directly within the app settings.
• Complete Permanent Deletion: Uninstalling the Daily Cashbook app from your Android or mobile device will immediately and permanently erase all locally saved transaction logs, categories, and application preferences. Because we do not keep server backups, erased data cannot be restored by Emperor Smart Solutions.

7. Children's Privacy (COPPA & Global Standards)

Daily Cashbook is designed as a general utility tool for managing financial records and is not targeted at children under the age of 13. We do not knowingly solicit or collect personal information from minors. If you are a parent or guardian and discover that a child has provided us with personal data, please contact us immediately so we can assist in resolving the issue.

8. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect enhancements in app functionality, regulatory requirements, or organizational updates. Any modifications will be posted directly on this official domain page (https://cashbook.vardaansmartsolutions.com/) with an updated "Last Updated" timestamp.

We encourage users to review this page periodically to remain informed about how we protect user privacy.
