 # Private Facebook Wrapper (Android)
 
-A high-security, open-source WebView wrapper for Facebook, engineered to provide a "Digital Faraday Cage" for your social media usage. This app is designed to break Facebook's cross-app tracking and hardware fingerprinting.
+A high-security, open-source WebView wrapper for Facebook, engineered as a **Digital Faraday Cage** for your social media usage. This app is architected to break Facebook's cross-app tracking, hardware fingerprinting, and persistent background telemetry.
 
 ## 🛡️ Advanced Privacy Features
 
-This wrapper goes beyond standard "privacy browsers" by implementing deep-level request interception:
+This wrapper goes beyond standard "privacy browsers" by implementing deep-level request interception and execution isolation:
 
-*   **Controlled Fetch Engine**: Unlike standard wrappers, this app intercepts Main Frame GET requests and performs a manual fetch. This allows for:
+*   **Controlled Fetch Engine**: The app intercepts all Main Frame GET requests and performs a manual fetch via `HttpURLConnection`. This allows for total control over the request lifecycle.
-    *   **Total X-Requested-With Stripping**: Completely removes the header that identifies the Android app to Facebook's servers.
+*   **Total X-Requested-With Stripping**: Completely removes the header that identifies the Android app to Facebook's servers, making the traffic appear as a generic mobile browser.
-    *   **Strict Content Security Policy (CSP)**: Enforces a custom CSP that prevents Facebook from loading scripts or tracking pixels from third-party domains.
+*   **External Link Isolation (The "Double-Lock")**: Implements a strict two-stage gatekeeper. Any navigation attempt to a non-Facebook domain is immediately "snatched" by the OS and forced into your default system browser. This ensures third-party sites are never rendered inside the app's persistent container, preventing cross-site leakage.
-*   **Fingerprint Mitigation**: Injects a hardened JavaScript layer to:
+*   **Strict Content Security Policy (CSP)**: Enforces a custom, injected CSP that physically blocks the browser from loading scripts, tracking pixels, or frames from third-party domains.
-    *   **Disable WebRTC**: Prevents your local/VPN IP address from being leaked via STUN servers.
+*   **Fingerprint Mitigation**: Injects a hardened JavaScript layer (on `onPageFinished`) to:
-    *   **Canvas/WebGL Muffling**: Returns empty data for canvas read-back attempts used in hardware sketching.
+    *   **Disable WebRTC**: Nullifies `RTCPeerConnection` to prevent local/VPN IP leaks via STUN/TURN queries.
-    *   **Hardware Masking**: Reports generic values for CPU cores and device plugins.
+    *   **Canvas/WebGL Muffling**: Disables 2D and 3D canvas read-back attempts used for hardware sketching.
-*   **Zero Permissions**: Requires **no access** to your contacts, location, microphone, camera, or files.
+    *   **Privacy-Hardened User-Agent**: Spoofs a generic, non-identifiable Chrome-on-Android string to prevent device-specific tracking.
+*   **Sponsored Content Removal**: Includes an integrated mutation observer that identifies and removes "Sponsored" and "Suggested" posts in real-time from the DOM.
+*   **Zero Permissions Architecture**: Requires no access to contacts, location, microphone, camera, or files. The app is a self-contained silo.
 *   **Network Hardening**: Uses `network_security_config` to force HTTPS and block all cleartext traffic at the OS level.
 
 ## 🚀 Technical Stack
 
 *   **Language**: Kotlin
-*   **Architecture**: Intercept-and-Modify (using `shouldInterceptRequest` and `HttpURLConnection`).
+*   **Security Layer**: Intercept-and-Modify architecture using `shouldInterceptRequest` and `shouldOverrideUrlLoading`.
-*   **UI**: Edge-to-edge layout with dynamic Window Inset handling for modern Android status bars.
+*   **Hardware Acceleration**: Uses hardware-layer rendering for high-performance video and media playback without sacrificing privacy.
-*   **Persistence**: Session cookies are flushed to disk on page finish to ensure login persistence without background syncing.
+*   **Persistence**: Session cookies are manually flushed to disk on navigation, ensuring login stability without the need for background sync services.
+*   **Zero-Background Footprint**: Optimized for use with app-freezing tools (like Shelter or Hail). The app maintains no background services, receivers, or workers.
