I completely agree with the concern about data logging, especially for developer tools. I constantly worried about pasting sensitive JWTs or JSON payloads into random online formatters. That frustration actually led me to build https://encryptdecrypt.org. It’s a suite of 330+ utilities (AES, Base64, Hashing) that run 100% client-side in the browser using the WebCrypto API. Data never touches a server. Keeping these utilities offline/in-browser feels like the only way to guarantee privacy these days.
