This app runs entirely in your browser. No account or sign-up
needed. No data is collected, no cookies, no analytics, no
tracking.
Your uploaded data is cached in your browser so the app loads
instantly on return visits. Everything stays on your device and can
be cleared from Settings.
If you use the play button, the artist name and track title are
sent to YouTube to find a match. Album art is fetched from Spotify
using only the track title and artist name. Neither request is
linked to your identity in any way. If you don't use the player,
nothing leaves your browser.
Last.fm scrobbling is also optional. If you choose to link your
Last.fm account, track name, artist, and album are sent to Last.fm
when you listen. No other data is shared. You can unlink at any
time from Settings.
