Is SummYT - YouTube Summarizer safe?

Clean risk

SummYT - YouTube Summarizer sends selected YouTube video IDs and transcript lines to use.summyt.app.

When you use the SummYT overlay on YouTube, the extension sends the current video URL or ID to use.summyt.app to request a summary. It also captures YouTube timed-text transcript data for that video, converts it into timestamped lines, and uploads those lines to use.summyt.app.
