Is Netflix Dual Subtitles - Subtitle Translator safe?

Netflix Dual Subtitles sends subtitle text, watch URLs, and page titles to Amplitude analytics on each translation event.

Each time a translation is triggered, the extension forwards the subtitle content, the Netflix watch URL, and the page title to Amplitude's analytics API along with a persistent device ID stored in browser local storage. Storage change events, including license key writes and user settings, are also transmitted to the same Amplitude endpoint. The persistent device ID allows Amplitude to link all translation activity to a single device over time.
