Security & Privacy

Your data never
leaves your browser.

DataForge parses, cleans, and charts your files entirely inside your browser tab. No upload to any server. No third-party processing. GDPR-safe by architecture, not just by policy.

Zero network transmission
File bytes never leave your machine. Mathematically impossible to intercept.
No content analytics
We track upload counts, never file contents. We cannot read your data.
No server-side processing
All parsing and cleaning runs in-browser via JavaScript.
GDPR-safe by architecture
You can't leak what you don't store.
