Is this SQL Formatter safe for sensitive data & credentials?

Yes, 100%. All processing runs client-side in your local browser memory. No text, tokens, payloads, or logs are ever transmitted to any remote server or analytics engine.

Can I use SQL Formatter offline without internet?

Partly. This tool runs on client-side JavaScript with no external API calls, so once it is open it keeps working if your connection drops. Pages are not cached for offline use, so loading a tool needs a connection.

How does URL state sharing work?

When you click the share (link) icon, your input is compressed into a URL hash fragment (#data=...) and the link is copied to your clipboard, without storing anything on a database server.
