Log in to spotify.com/account/privacy, scroll to the bottom and request "Extended streaming history". Spotify emails you a zip file within ~3 weeks. That's the file you drop here. (The basic "Account data" zip only covers the last year — you want the extended one for a real Wrapped.)

Everything happens in your browser. No file is uploaded to any server, no account is needed, and nothing is stored. Refreshing the page wipes everything. The page does fetch artist and album artwork from Deezer's public catalogue (no login) — if you'd rather it didn't, just stay offline while it loads.

Spotify's official Wrapped uses some private signals (skip behaviour, listening segments, podcast separation) we can't see. Numbers here come straight from your raw history — sometimes higher, sometimes lower than Spotify's. Plays under 30 seconds are still counted; phantom multi-week records are capped at 10 minutes per play.
