  • Multi-Platform Support: Refactored to a Federated Plugin architecture, enabling seamless support for Android, iOS, and Web.

  • Enhanced Web Privacy:

  • Data Leak Prevention: Added blockers for "Right-Click" (context menu), "Copy", and "Drag-and-Drop" to prevent unauthorized saving of text and images.

  • Anti-Print Logic: Implemented CSS Injection to hide app content automatically if the user attempts to print the page (Cmd/Ctrl + P).

  • UI Protection: Added user-select: none to prevent text highlighting and selection on sensitive screens.

  • Window Focus Tracking: Implemented "Soft Privacy" via CSS blur filters that trigger when the browser tab is switched or the window loses focus.

  • Modern Web Interop: Built using the latest package:web and dart:js_interop for WebAssembly (Wasm) compatibility and future-proofing.

  • Lifecycle Management: Added robust cleanup of JavaScript event listeners and injected styles when the PrivacyMask widget is disposed to prevent memory leaks and restore normal browser behavior.
