Yes. DriftFM uses your Last.fm profile to select seed artists and build personalized recommendations.
Not if your Last.fm profile is public — just enter your username and start drifting, read-only. Connecting (authorizing) with Last.fm is needed for scrobbling and for private profiles.
Every playlist holds 20 tracks from artists you have never scrobbled, and they play back to back automatically. When the queue ends you can save the ones you liked, share the whole queue, or build a new one.
No. Scrobbles are only sent when you explicitly press the scrobble button.
We store minimal data needed to generate recommendations: your Last.fm username, a session key only if you connect, preferences, favorites, and blocklist.
Yes — after connecting with Last.fm, use the in‑app deletion request, or contact drift@skaffa.net.
