YTM Lux privacy policy

Last updated: October 31, 2026

YTM Lux is a browser extension that changes how YouTube Music looks and adds listening tools. It has no account, no server and no analytics.

What stays in your browser

Your settings, saved lyrics and the original versions you pick are stored in your browser's extension storage. They never leave your computer and are deleted when you remove the extension.

What is sent, and to whom

• Lyrics: to find lyrics, the title, artist, album and length of the song you are playing are sent to LRCLIB (lrclib.net), a public lyrics database, and to YouTube Music itself. No personal information is sent.
• Song versions and the queue: searches for other versions of a song, and for more songs when a queue runs out, are made to YouTube Music, the site you are already using.
• Album covers: the cover image of the playing song is read from Google's image servers to pick background colours.

Nothing is sent to the developer of YTM Lux. No data is sold, shared for advertising, or used for any other purpose.

Playlist backup

When a backup runs, the extension reads your own YouTube Music playlists (read-only) and saves them as files in your computer's Downloads folder. The files stay on your computer.
