Is DeepL / MultiTranslate safe?

Clean risk

DeepL / MultiTranslate sends selected page text to the chosen translation service when you translate it.

When you use the context menu, popup, or selection label to translate text, the extension reads the selected text from the current page. It places that text into a DeepL, Bing/Microsoft Translator, or Google Translate URL and opens the translation service in a popup or embedded view.
