Is B站bilibil弹幕下载生成ASS字幕 safe?

Low risk

B站bilibil弹幕下载生成ASS字幕 can send downloaded Bilibili danmaku and video metadata to a server-supplied URL.

When a user starts a download, the extension posts Bilibili video metadata and identifiers to bilibili.flysay.com/config.json along with a persistent extension install ID and a Bilibili user ID parsed from the page. That remote configuration can provide an uploadDMUrl, which the extension then uses to post downloaded danmaku segments, video title, media ID, and episode metadata.
