Fast Video Link — privacy policy (also at https://fastvideolink.com/privacy)

The extension looks at what the open tab loads (addresses, type, size) and its title to list the videos; the list stays in the browser for that tab and is cleared when the tab leaves the page. There is no analytics, advertising or tracking, and nothing is sold. Videos are downloaded straight from their site. The optional helper runs on the computer and runs yt-dlp and ffmpeg, which contact only the video's site; its installer fetches yt-dlp, ffmpeg and (on Windows) Python from their official sources.

Data leaves the computer only when you press Share or Copy link with a link place chosen in the settings, and only to that place: the fastvideolink.com link server (the video's and page's addresses, title and quality; the video is kept until it goes 2 hours unwatched; accounts keep a login, a PBKDF2 password hash, a fingerprint of their key, device sign-in keys and the day's upload volume; IP addresses count the day's traffic, web server request logs with IP addresses are kept 14 days), a server of your own, or your Google Drive (a "Fast Video" folder, files shared by link; the app sees only files it made). The server runs in Oracle Cloud (Stockholm). Nothing is shared with anyone else.
