Privacy Policy

Last updated: February 25, 2025

Aktechvn ("we", "our", or "us") built the QR Scanner app as a free/ad-supported application. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application.

1. Information We Collect

We may collect the following types of information:

• Camera Access: Our app requires access to your device's camera to scan QR codes and barcodes. Images captured by the camera are processed locally on your device and are not transmitted to our servers.
• Photo Library Access: If you choose to scan a QR code from an existing image, we access your photo library only for that specific purpose.
• Scan History: Your scan history is stored locally on your device. We do not upload or sync this data to any external server.
• Device Information: We may collect non-personal device information such as device model, operating system version, and app version for analytics and improvement purposes.
• Advertising Data: Our app may use third-party advertising services that collect data to serve personalized ads. This may include advertising identifiers provided by your device.

2. How We Use Your Information

We use the information we collect to:

• Provide and maintain the QR scanning functionality
• Improve, personalize, and expand our app
• Understand and analyze how you use our app
• Display relevant advertisements
• Detect and prevent technical issues

3. Third-Party Services

Our app may use the following third-party services that may collect information:

• Google Play Services
• Google AdMob
• Firebase Analytics

Each of these services has its own privacy policy governing the use of collected information. We encourage you to review their policies.

4. Data Security

We value your trust in providing us your information and strive to use commercially acceptable means of protecting it. However, no method of transmission over the Internet or method of electronic storage is 100% secure, and we cannot guarantee its absolute security.

5. Children's Privacy

Our app does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers.

6. Data Retention

Since scan data is stored locally on your device, you can delete it at any time by clearing the app data or uninstalling the application. Analytics data collected by third-party services is retained according to their respective policies.

7. Your Rights

You have the right to:

• Access, update, or delete your scan history within the app
• Opt out of personalized advertising through your device settings
• Revoke camera and photo library permissions through your device settings
• Request information about the data we process

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
