Security in PdfEditorApp PDF Password Protection Users can set or remove passwords on any PDF file. Passwords are handled securely and never stored. File Access All file operations (open, edit, save, export) include error handling and user-friendly messages. Sensitive operations are only performed with explicit user action. Permissions The app requests only the minimum permissions required (storage, camera). All permissions are explained to the user and handled gracefully if denied. Data Privacy No user data is sent to external servers. All processing is done locally on the device. Reporting Issues If you find a security vulnerability, please report it via a GitHub issue or contact the maintainer directly.
