Thank you for using QReader & Barcode Scanner (“the App”). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how our app handles permissions, device access, user data, and third-party advertising services.
The app is designed as a lightweight application. We do not directly collect or store personally identifiable information (PII). All scan data is processed locally on your device and is not transmitted to any server.
However, third-party advertising services (AdMob and Pangle) may collect certain information such as device identifiers, IP address, advertising ID, app usage data, and location (if enabled) to deliver personalized ads and measure ad performance. We do not control this data collection.
| Permission | Purpose | Data Collected / Shared |
|---|---|---|
| android.permission.CAMERA | Access camera for scanning QR codes and barcodes | None sent or stored |
| android.permission.INTERNET | Used for optional content, updates, and ad loading | Non-personal device info and ad interactions for ads |
| android.permission.ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION | Optional location for personalized ads (via AdMob or Pangle) | Shared with ad providers if enabled, not stored by us |
| android.permission.VIBRATE | Vibration feedback when scanning | None |
| android.permission.FLASHLIGHT | Enable flashlight for scanning in low light | None |
The app’s core scanning features work entirely offline. Network access is required only for non-personal purposes such as checking for updates and loading ads.
The app integrates third-party advertising services provided by Google AdMob and Pangle. These services may collect and process certain non-personal information about your device, app usage, and interactions with ads, in accordance with their own policies. This data is used for ad delivery, personalization, and measurement.
Since the app itself does not collect personal or sensitive data, all core processing occurs locally on the device. Data collected by third-party ad services is handled according to their respective policies.
This app is suitable for general audiences and does not target children under the age of 13. No data from children is collected or stored.
We may update this Privacy Policy periodically. Updates will be published in the app and/or on the official listing page. Continued use of the app after updates means you accept the new version.
