# Privacy and local file processing

KitDevs is structured so the main file-processing workflow runs in the user's browser.

## Summary

### User files

Selected files are read by the browser for compression or conversion. The main workflow does not require uploading files to a backend for processing.

### External libraries

The app can load third-party libraries such as JSZip and FFmpeg.wasm from CDNs to enable ZIP files, conversion and audio/video processing.

### Analytics

The site uses Vercel Web Analytics to understand page visits. Analytics does not need to receive the files processed by the user.

### Recommendations

- Avoid processing sensitive files on shared devices.
- Use updated browsers for better security and compatibility.
- For very large files, prefer computers with more memory.
