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.
Data on Your Device
Scan History
Your scan history, favorites, and the codes you create, including optional thumbnail images, are stored in the App's private storage on your device, which other apps cannot access. This data never leaves your device unless you choose to back it up via Google Drive or export it.
Permissions
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 from URL
If you use Scan from URL, the App downloads the image from the address you enter. Decoding happens on your device.
Contacts (optional)
When you create a contact QR code, you may pick a contact from your phone. The selected contact is read on your device only to fill in the QR code and is never uploaded.
App Lock (optional)
You can protect the App with a PIN and/or biometrics. The PIN is stored on your device only as a salted hash. Biometric checks are handled by Android; the App never receives your fingerprint or face data.
Backup and Restore
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 at any time in the App's settings. Backup files can be deleted from Google Drive (see Data Deletion below).
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.
In-App Purchases
Pro is an optional one-time purchase that removes ads and unlocks extra features. It is processed by Google Play Billing. We do not receive your payment details; the App only checks with Google Play whether Pro has been purchased.
Advertising
The App displays advertisements using the following third-party advertising SDKs:
| SDK | Data Collected | Purpose |
|---|---|---|
| Google AdMob | Device identifiers (Advertising ID), app interactions, diagnostics | Ad serving & personalization |
| Unity Ads | Device identifiers (Advertising ID), app interactions, diagnostics | Ad serving via AdMob mediation |
These SDKs may collect data automatically to serve relevant advertisements. You can opt out of personalized ads through your device's advertising settings:
- Android: Settings → Privacy → Ads → Delete advertising ID
Where required (for example, in the EEA and the UK), the App asks for your consent through Google's consent form before showing personalized ads. Users who purchase Pro see no ads.
For more information, see: Google Privacy Policy | Unity Privacy Policy
Analytics & Crash Reports
The App uses the following Google Firebase services:
- Firebase Analytics - app opens, session duration, and feature usage
- Firebase Crashlytics - crash logs and error reports
- Firebase Remote Config - app settings delivered without an app update
This data is linked to a random app-instance identifier, not to your name or email, and is used only to improve the App's performance and user experience.
