Import your full history
Upload the "Extended streaming history" export from Spotify to get stats from the day you created your account. Don't have it yet? Here's how to get it.
Your files are read in your browser. Only the track, the time and how long you listened are sent to stats.lk. IP addresses and device info in the export never leave your device. Plays shorter than 30 seconds are skipped, and importing the same file twice won't create duplicates.
