Last Updated: December 16, 2025

This Privacy Policy describes how ExpenseBuilder ("we", "us", or "our") collects, uses, and discloses your information.

1. Overview

ExpenseBuilder is an offline-first financial tracking application. We believe your financial data is personal and private. We do not collect, store, or share your personal data on our servers. All data you enter into the application is stored locally on your device in a secure database.

2. Information Collection and Use

Personal Data

We do not require you to create an account, log in, or provide any personal identification information (such as name, email, or phone number) to use the application.

Financial Data

All financial transactions, expenses, and account details you enter are stored locally on your device's internal storage using an encrypted database (Room Database). This data is never transmitted to us or any third-party cloud server for storage or analysis.

3. App Permissions

The app requests the following permissions for specific functionalities:

• INTERNET (android.permission.INTERNET):

  • Purpose: This is used solely to fetch live currency exchange rates from a public API (open.er-api.com).

  • Note: Your financial data is never sent over the internet. Only the currency pair (e.g., "USD" to "INR") is transmitted to fetch the current rate.

• ACCESS WIFI STATE & NETWORK STATE (android.permission.ACCESS_WIFI_STATE):

  • Purpose: This is required for the "PC Dashboard" feature. The app creates a local HTTP server on your device to allow you to view and manage your expenses from your laptop browser via your local WiFi network.

  • Note: This connection happens entirely within your local network. No data leaves your local WiFi environment.

4. Third-Party Services

The application interacts with the following third-party service solely for currency conversion rates:

• Open Exchange Rates API: We use this service to provide up-to-date exchange rates. Their privacy policy can be viewed at https://open.er-api.com.

5. Data Retention

Since we do not host your data, we have no control over data retention. Your data remains on your device until you uninstall the application or manually clear the app data from your device settings.

6. Children’s Privacy

We do not knowingly collect personally identifiable information from children under 13. Since the app does not collect data, it is safe for all ages, but it is intended for use by adults for financial management.
