Security Architecture
100% Client-Side Processing
All file processing, data manipulation, and computations occur entirely within the user's browser using JavaScript. No files, data, or content are transmitted to our servers or any third-party services.
✓ Network Security Benefits:
- No outbound data transmission of user files
- No file uploads to external servers
- No API calls with sensitive data
- Works within air-gapped networks once cached
- No WebSocket or persistent connections
