🛠 Prerequisites

- Root Access: Essential for reading/writing to /data/data/. - Target Browser Installed: The app you're moving to must be installed. - Storage: ~100MB of free space for temporary processing and backups.

🚀 How to Use

1. Open the App: Grant root permissions when prompted. 2. Select Source: Type or paste the package name of your current browser (e.g., org.mozilla.firefox). 3. Select Target: Type or paste the package name of your new browser (e.g., com.brave.browser). 4. Start: Tap START MIGRATION and watch the real-time log. 5. Verify: Open your new browser and check that your data is there. 6. Cleanup: Use DELETE BACKUPS to remove the temporary safety copies.

🔒 Security & Privacy

- Local Only: No data ever leaves your device. No analytics, no cloud, no internet required. - Input Validation: Strict regex filtering on package names to prevent shell injection. - Sandboxed Execution: Scripts run in a controlled environment under /data/local/tmp. - SELinux Aware: Automatically restores file contexts using restorecon to prevent "App Not Responding" or permission issues.

⚠️ Known Limitations

- Chromium Passwords: Due to Android Keystore encryption, passwords moved between different apps (e.g., Chrome → Brave) may not be decryptable. Migration works best when reinstalling the same app or moving within identical signature families. - Tabs: Intentionally skipped to prevent session crashes caused by version mismatches.

ℹ️ Important

Root access is required (KernelSU, Magisk, or SuperSU) to access protected browser data directories.
