Turn off purchase sharing and stop sharing a payment method

If you're the family organizer and you want family members to pay for purchases themselves, turn off purchase sharing: 

1. Go to your Purchase Sharing settings in Settings on your iPhone or iPad or in System Settings on your Mac.
2. Turn off purchase sharing:

• • On your iPhone or iPad, tap Stop Purchase Sharing.
  • On your Mac, click Turn Off, then click Stop Purchase Sharing.

When purchase sharing is turned off, you stop sharing your purchases and lose access to the purchases made by your other family members. However, you can continue to share subscriptions like Apple TV+ and Apple Arcade, but everyone must use their own payment method for purchases.
