Getting started

Your proof is in Spotify's vault.

Cosign scores your real listening history — the Extended Streaming History export only Spotify can hand you. Request it today; it's usually ready within a few days.

1. 1
   Open Spotify's privacy page

   Go to spotify.com/account/privacy and scroll to Download your data.

2. 2
   Tick “Extended streaming history”

   Not the default “Account data” box. Only the extended export carries the per-play timestamps Cosign needs to tell how early you were.

3. 3
   Request it — then live your life

   Spotify emails a download link when it's ready — usually a few days (they allow up to 30). Meanwhile: follow people on the leaderboard so your board is warm when your score lands.

4. 4
   Drop the .zip on Cosign

   When it arrives, drop the file as-is on the home page — we read the Streaming_History_Audio files inside it. No unzipping needed. Questions about the export itself? See the full guide.
