Frequently Asked Questions

Is my code saved anywhere?

Your code is automatically saved to this browser's local storage as you type, so it survives a page refresh — but it's never sent to a server. Use Export (ZIP/JSON) to keep a permanent copy.

Can the JavaScript in my code access the internet or my files?

The preview runs in a sandboxed iframe with restricted permissions (scripts, forms, and modals only) — it can't navigate the top-level page or access anything outside the preview itself.
