How are secrets detected?

Keys containing words like secret, token, key, or password are treated as secrets.

What happens with duplicate keys?

They're flagged in a warning banner and the last occurrence is used in the output.

Are quoted values handled?

Yes, surrounding single or double quotes are stripped automatically.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
