Privacy Policy

Welcome to QR Code Master. We respect your privacy and are committed to protecting your personal data. This privacy policy explains how our mobile application handles your information.

1. Overview

QR Code Master is designed to operate 100% offline. All scanning, generation, and history management take place entirely on your local device. We do not collect, store, or transmit any personal information to external servers.

2. Permissions & Data Access

Our app requests only the minimum permissions necessary for core functionality:

• Camera Permission: Required solely for real-time QR code and barcode scanning through your device camera viewfinder. Camera feeds are processed locally in real time on your device and are never recorded, cached, or transmitted externally.
• Storage / Gallery Access: Used strictly when you choose to load an image from your device gallery to scan a QR code, or when you export generated QR codes as PNG or PDF files.

3. Local Data Storage & Security

All scan history, favorites, and custom configurations are stored locally on your device using a secure local SQLite/Room database. If you use the AES-256 encryption feature, your data is cryptographically secured with your user-defined passphrase locally on your device.

4. Third-Party Services & Analytics

QR Code Master does not integrate any third-party analytics trackers, advertising networks, or cloud synchronization services. Your data never leaves your device.

5. Children's Privacy

Our app does not knowingly collect or solicit personal information from children under 13. Because all data is stored locally on your device, no personal data is collected by us whatsoever.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
