Privacy Mask 🛡️ #

A lightweight, high-performance Flutter widget that protects sensitive information by preventing screen recording and screenshots at the OS level.

🌟 Why Privacy Mask? #

In 2025, mobile security is more than a feature—it's a requirement. Whether you're building a Banking, Healthcare (HIPAA), or Private Messaging app, privacy_mask ensures that sensitive data stays on the user's screen and out of their camera roll.

• Android Support: Uses FLAG_SECURE to block screenshots and screen recordings system-wide.
• iOS Support: Utilizes a secure layer hack (isSecureTextEntry) to black out recordings and screenshots.
• Lifecycle Aware: Automatically enables/disables protection as the widget enters or leaves the screen.

Protection States #

You can toggle protection dynamically. When enabled, the OS prevents the UI from being captured in the screen buffer.

Screenshot Prevention #

When a user attempts to take a screenshot or record the screen while protection is active, the OS intercepts the action.

⚠️ Warning #

Note on Testing: Screenshot prevention is a hardware-level feature. It will not work on the iOS Simulator because the Simulator bypasses the iOS Render Server. To verify iOS protection, you must use a physical device and test using Screen Recording or Screen Mirroring.
