Is Google Apps Script Tools safe?

Google Apps Script Tools adds UI enhancements to the Apps Script editor and stores theme preferences locally in browser storage.

The extension injects additional controls into the Google Apps Script IDE, including a theme switcher, word-wrap toggle, and file-list toggle. It loads bundled HTML, CSS, and JavaScript from the extension package itself and uses chrome.storage.sync to save the user's selected theme across sessions. No user data is transmitted to any external server.
