Client-side processing
Every operation runs in your browser. Files are never transmitted anywhere — not even to our own servers.
No file access
Documents stay in your browser’s memory during processing and are discarded when you close the tab. We never see, access, or store your files.
Minimal data
Only account info and anonymous usage counts for rate limiting, plus Vercel Analytics for basic page views. No file data, ever.
