If you have an Apple iPhone or iPad, you can delete your account by going to the App Store and selecting “Delete Account.” If you don’t have an Apple device, you can also delete your account by going to the website apple.com/account and clicking on the “Delete Account” link.
You can’t access iTunes Store, App Store, or Apple Books purchases you made in the past if your whole Apple ID is deleted. All of your photos, videos, and documents saved in iCloud—including any purchases you make with your account—will be erased. Any subscriptions you joined up for using your Apple ID will come to an end.
Select the user account where you’d like to apply your changes. Select your account in Settings. Select Users & Accounts, then select your account. Subscriptions are the next option on this screen. Choose the subscription that you want to manage, then click Cancel Subscription.
Open the Apple Music app on your Mac. iTunes for Windows may also be used to access this feature. Select Account > View My Account from the menu bar. You could need to sign in with your Apple ID and password. Select Manage Devices from the menu bar… If you wish to remove a device, select Remove.
On your iPhone, open the Settings program. After that, go to iTunes & App Store and select View Apple ID from the drop-down menu. Then click Delete this Device on the following screen. To get back to your Apple ID account page, press the Back button.
