Cancel a membership in the app that manages it:
For a Digital DJ Pool DJ membership, open Settings → Billing, choose Cancel Subscription, and follow the confirmations.
For an Artist app membership, open the Artist app Billing page, choose the cancel option for that membership, and follow the prompts.
If you use both apps, cancel each membership separately. Cancelling stops the next renewal. You keep access through the paid-through date, and the current paid period is not refunded.
MP3 files already saved to your device remain there after access ends. Your online Library is not a promise that every track will remain hosted or available to download again.
