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.

Which mode should I use?

Keep is the lightest change. Web and Strong make a smaller file for sending.

Can I get the original back?

Keep an original copy if you use Web or Strong. Those modes rebuild the pages.

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?

On Free, nothing is uploaded. The file stays in your browser and disappears when you close the tab. Pro and Studio add API, CLI, MCP, and apps, not a file locker.

Can I use this at work?

Yes. Use the site in the browser for free. For the same tools in your workspace, open Apps and start with the API, CLI, or MCP on Pro.
