Privacy Policy – QR Scanner Pro+ & Barcode

📋 Overview

QR Scanner Pro+ & Barcode ("the App"), developed by Golden Roots, respects your privacy. This Privacy Policy explains what data the App accesses, how it is used, how it is shared, and your choices regarding your data.

By using the App, you agree to the collection and use of information in accordance with this policy.

🔐 Permissions & Local Data

Camera Access

The App uses your device's camera to scan QR codes and barcodes. All scan processing is performed locally on your device. No camera data is transmitted to any server or third party.

Photo Library Access

The App may access your photo library to scan QR codes from saved images. Selected images are processed entirely on your device and are never uploaded to any external server.

Scan History

Your scan history, including scanned content and optional thumbnail images, is stored locally on your device using an encrypted local database. This data never leaves your device unless you explicitly choose to back it up via Google Drive.

☁️ Google Drive Backup

The App offers an optional Google Drive backup feature. When you choose to use this feature:

The App requests access to Google Drive's app-specific storage (appDataFolder) only.
Your scan history data is encrypted in transit (HTTPS/TLS) and stored in a private folder that only this App can access.
No other files on your Google Drive are accessed, read, or modified.
You can disconnect your Google account or delete the backup data at any time through the App's settings.

🔑 Google Sign-In

If you use the Google Drive backup feature, you will be asked to sign in with your Google account. The App accesses only the following information:

Email address — to display which account is connected
Display name — to show your name in the settings screen
Profile photo — to show your avatar in the settings screen

This information is used only for display purposes within the App and is not stored on any external server or shared with any third party.
