# Privacy Policy for DocuSense

## Overview
DocuSense respects your privacy. This app processes documents such as receipts and utility bills.

## Data Collection
DocuSense may collect limited personal data when users choose to sign in using Firebase Authentication, including email address and a user identifier (UID). This information is used only for authentication and basic app functionality.

## On-Device Processing
All document processing (OCR and analysis) is performed locally on your device. Images, extracted text, and document contents are not transmitted to external servers.

## Third-Party Services
The app uses Firebase Authentication (Google) for optional user login. Firebase may process authentication data such as email address and user ID in accordance with its own privacy policies.

## Data Usage
Authentication data is used only for account login and functionality. All document data remains on your device unless explicitly shared by the user. No personal data is used for advertising or tracking.
