Are my files uploaded?

No. On Free, files stay in your browser and are gone when you close the tab. Nothing is sent to a server unless you use the API, CLI, MCP, or apps.

What if I forget the password?

There is no recovery. Unlock PDF only works when you still know the password.

Yes. Browser tools run on your device. Files are not stored on a server unless you use the API, CLI, MCP, or apps.

What happens to my file?

Can I use this at work?
