Take turns picking the album. Listen, rate, discuss, and watch your taste evolve.
No, but full-track playback inside the app requires one. Without it, you can listen to the standard 30-second previews Apple provides, or open any pick in your music app of choice.
In your iCloud account, in a private Turntable Club CloudKit container. Nothing is sent to any Turntable Club server because there isn't one. Club content syncs to other members through Apple's CloudKit sharing.
Two things to check: (1) they need to have signed in with their iCloud account on their device, and (2) they need to have tapped the share invitation link you sent them via Messages, Mail, or AirDrop. The link opens the app and accepts the share automatically.
The "Differing opinions" / track-highlights / club-summary cards use Apple Intelligence, which requires iOS 26+ on a supported device. The rest of the rating and reveal experience works without it.
Album metadata comes from Apple Music's catalog. If something looks wrong, it's probably the catalog entry — try removing and re-adding the album, which will pick up any catalog corrections.
If you've enabled auto-pick (Profile → Auto-pick on next turn, or per-club in Club Settings), the top of your queue is applied automatically when the period rolls over. The Upcoming tab shows what would auto-pick so you can override before the boundary.
Club Settings → "Leave club" at the bottom. Your past picks stay in the club's history for the other members; new content from the club stops syncing to you.
Sign in to iCloud and manage the Turntable Club container under iCloud storage. Removing it there wipes the iCloud-stored data. Also delete the app from your devices to remove local copies.

Privacy Policy — short version: nothing is collected; everything lives in your iCloud.
