Every tool runs in your web browser. Text you paste and files you open are processed on your own device. We do not upload, store or sell them, and you do not need an account.

If you switch theme, that choice is saved in your browser so the site remembers it. Pages load fonts from Google Fonts, so your browser connects to Google’s servers to download them. We do not use advertising or tracking cookies; if that changes, this notice will be updated first.
