Is Learn Languages on YouTube & Netflix - zeroStudy safe?

Medium risk

Learn Languages on YouTube & Netflix - zeroStudy sends watch-session details, an access token, and a bundled secret to Supabase.

When a YouTube or Netflix page is closing, the extension builds a beacon with the session ID, user ID, video ID, watch time, current video position, the current access token, and a hardcoded function secret. It sends that beacon with navigator.sendBeacon to a Supabase Edge Function endpoint.
