+# 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.
+
+## 🛡️ Advanced Privacy Features
+
+This wrapper goes beyond standard "privacy browsers" by implementing deep-level request interception:
+
+*   **Controlled Fetch Engine**: Unlike standard wrappers, this app intercepts Main Frame GET requests and performs a manual fetch. This allows for:
+    *   **Total X-Requested-With Stripping**: Completely removes the header that identifies the Android app to Facebook's servers.
+    *   **Strict Content Security Policy (CSP)**: Enforces a custom CSP that prevents Facebook from loading scripts or tracking pixels from third-party domains.
+*   **Fingerprint Mitigation**: Injects a hardened JavaScript layer to:
+    *   **Disable WebRTC**: Prevents your local/VPN IP address from being leaked via STUN servers.
+    *   **Canvas/WebGL Muffling**: Returns empty data for canvas read-back attempts used in hardware sketching.
+    *   **Hardware Masking**: Reports generic values for CPU cores and device plugins.
+*   **Zero Permissions**: Requires **no access** to your contacts, location, microphone, camera, or files.
+*   **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`).
+*   **UI**: Edge-to-edge layout with dynamic Window Inset handling for modern Android status bars.
+*   **Persistence**: Session cookies are flushed to disk on page finish to ensure login persistence without background syncing.
+
