Privacy Policy for QR Scanner: Barcode Scanner
Privacy Policy for QR Scanner: Barcode Scanner
Effective Date: August 12, 2026
This Privacy Policy explains how QR Scanner: Barcode Scanner ("the App") collects, uses, and protects your information. To provide a free, stable, and continuously improving experience, our application utilizes third-party services for analytics, crash reporting, and advertising.
By downloading and using the App, you agree to the collection and use of information in relation to this policy.
1. Information Collection and Use
While the core functionality of scanning QR codes and barcodes is processed locally on your device, the App requires internet access to utilize third-party integrations (such as Firebase and AdMob). These third-party services may collect specific identifiers and usage data to serve advertisements, monitor app performance, and deliver push notifications.
We do not collect or transmit your personal camera frames, scanned text, or generated QR codes to our servers. All barcode decoding happens securely on your device.
2. Required Device Permissions
To function correctly, the App requests the following permissions:
Camera (CAMERA): Required to scan QR codes and barcodes in real-time. Image data is processed on-device and is never uploaded.
Internet (INTERNET): Required to fetch advertisements, send crash reports, and receive push notifications.
Wi-Fi Connections (ACCESS_WIFI_STATE, CHANGE_WIFI_STATE): Used strictly to allow the App to automatically connect your device to a network when you scan a Wi-Fi QR code.
Notifications (POST_NOTIFICATIONS): Allows the App to send you relevant alerts, updates, and messages via Firebase Cloud Messaging.
System Alert Window (SYSTEM_ALERT_WINDOW): Allows the App to draw floating UI elements over other apps (e.g., a quick-scan floating widget), if this feature is activated by you.
Device Boot (RECEIVE_BOOT_COMPLETED): Allows the App's background services (like notification receivers) to resume seamlessly after your device restarts.
Vibration (VIBRATE): Used to provide physical feedback upon a successful scan.
3. Third-Party Services and SDKs
The App uses third-party libraries that may collect information used to identify you, track app performance, and serve ads. The data collected by these services is encrypted in transit and handled according to their respective privacy policies.
We use the following third-party services:
Google Mobile Ads (AdMob) & Advertising ID (AD_ID):
We use AdMob to display ads. This service collects your device's Advertising ID and usage data to provide personalized or non-personalized advertisements. You can opt out of personalized advertising or reset your Ad ID at any time via your Android device's Settings (Settings > Google > Ads).
AdMob Privacy Policy: https://support.google.com/admob/answer/6128543
Google Analytics for Firebase:
Collects app usage data, user engagement metrics, and device identifiers (such as the Firebase Installation ID) to help us understand how users interact with the App.
Firebase Analytics Policy: https://firebase.google.com/policies/analytics
Firebase Crashlytics & Performance Monitoring:
If the App crashes or experiences lag, these services automatically collect log data. This "Log Data" may include your device Internet Protocol ("IP") address, device name, operating system version, the App's configuration at the time of the crash, and the time and date of your usage.
Crashlytics Privacy Policy: https://firebase.google.com/support/privacy
Firebase Cloud Messaging:
Creates a unique device token to send you push notifications.
Google Play Services & ML Kit:
Provides core on-device machine learning for fast barcode scanning. Play Services may collect device-level diagnostic data.
Google Privacy Policy: https://policies.google.com/privacy
4. Data Security
We value your trust in providing us your information. All third-party SDKs used in the App (Firebase, AdMob) use secure, industry-standard encryption protocols (HTTPS) to transmit data. However, remember that no method of transmission over the internet or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.
5. Children’s Privacy
These Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we will be able to take necessary actions. Furthermore, advertisements served via AdMob are configured to comply with the Children's Online Privacy Protection Act (COPPA).
6. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately after they are posted.
