Is Double Subtitles for Prime by MovieLingo safe?

Clean risk

Double Subtitles for Prime sends Prime Video and Amazon subtitle text to Google Translate for second-subtitle display.

When subtitles change on Prime Video or Amazon pages, the extension reads the visible subtitle text from the page and sends it to Google Translate with the selected source and target languages. The translated text is returned to the content script and inserted back into the video page as a second subtitle line.
