At Oi Applications, the security and privacy of our users' data are our highest priorities. Oi QR Scanner is designed to be a "Privacy-First" application, meaning that your data remains on your device at all times.

The Oi Guard is a proactive security layer built into the scanner. It automatically analyzes every scanned URL for:

• Phishing Detection: Identifying suspicious keywords like wp-admin, login-, or secure-banking.
• Malicious Files: Flagging links pointing to potential malware (.apk, .exe, .zip).
• Masked Destinations: Detecting shortened URLs (e.g., bit.ly) to prevent redirection scams.
• Insecure Protocols: Flagging unencrypted HTTP connections.

• On-Device Intelligence: All machine learning operations (Barcode scanning) are performed strictly on-device. No images or scan data are transmitted to any external servers.
• Local Persistence: Scan history is stored in a private SQLite database accessible only by the application.
• System-Level Security: We rely on the device's native security (PIN, Pattern, or Biometrics) for overall data protection, rather than maintaining a redundant internal lock system.

Security updates are provided for the latest stable releases of the application.

We welcome reports from security researchers and users. If you believe you have found a security vulnerability in Oi QR Scanner, please follow these steps:

1. Email us: Send a report to security@oiapplications.com.
