Questions

Is my JSON sent anywhere?

No. It is parsed by your own browser, so API keys and private data stay with you.

Is my data private?

Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.

Is it free?

Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
