This Privacy Policy applies to the mobile application “QR & Barcode Reader”, developed and published by Ali Ben Fredj (“we”, “our”, “us”). It explains how we collect, use, and protect information when you use the app.

1. Information We Collect

We do not collect personal information such as your name, email, phone number, or contact details.

However, the app may automatically collect non-personal device and usage data through third-party SDKs used for analytics and advertising. This may include:

Device Information

• Device model, operating system version, language
  
  

• Screen size and hardware characteristics
  
  

Usage Data

• App interactions
  
  

• Session duration
  
  

• Crash logs (via Firebase)
  
  

Advertising Data

• Advertising ID (AAID)
  
  

• Approximate location (inferred from IP address)
  
  

This data is collected automatically to support ads, analytics, and app functionality.

2. Advertising & Analytics

QR & Barcode Reader uses Google AdMob to display advertisements.
AdMob may automatically collect:

• Advertising ID
  
  

• Approximate location
  
  

• App usage information
  
  

• Crash and performance data
  
  

These are used to:

• Deliver ads
  
  

• Measure ad performance
  
  

• Fight fraud and abuse
  
  

• Improve app stability
  
  

You can manage your ad preferences via:
👉 Google Account › Ads Settings
👉 Reset Advertising ID in Android Settings

Third-Party Policies:

• Google AdMob: https://policies.google.com/privacy
  
  

(No Start.io, AppLovin, Unity, or IronSource are used, since your app is AdMob-only.)

3. How We Use the Information

The collected data is used to:

• Display and optimize ads
  
  

• Improve app performance
  
  

• Analyze app usage trends
  
  

• Detect fraud and abuse
  
  

• Ensure the app works correctly on different devices
  
  

All data is processed automatically and encrypted in transit.

4. Third-Party SDKs

The app uses the following third-party SDKs:

• Google AdMob (advertising)
  
  

• Firebase Analytics (optional analytics)
  
  

• Firebase Crashlytics (crash reporting)
  
  

These providers may receive non-personal device or usage data.
Each provider follows its own privacy policy.

5. Data Security

We use security measures such as HTTPS/TLS to protect information transmitted between your device and our servers or third-party services.

While we strive to protect your data, no method of transmission is completely secure.

6. Children’s Privacy

QR & Barcode Reader is intended for general audiences.
It is not designed for children under the age of 13.
We do not knowingly collect data from children.
