zero-tracking json tools entirely in the browser is exactly the right shape for developer utilities - paste vagaries of production data into random sites is how secrets leak. do you do everything in-memory or is there any persistence at all, even local?

Thanks Mark, and fair question. The tools themselves do everything in memory: the JSON you paste is processed in JavaScript inside the tab. It isn't sent anywhere, and the tools don't write it to localStorage, cookies or IndexedDB. Close the tab and it's gone.

One honest caveat: the site does use Google Analytics for basic page-view and button-click counts. It never sees what you paste, but "zero-tracking" in my title was overstated, so I'm correcting that wording. If people would rather have no analytics at all, I'm open to switching to something more privacy-friendly.
