View, change, or cancel your subscriptions

Manage your subscriptions in Settings on your iOS device, in iTunes on a Mac or PC, or on Apple TV.

Some apps and services require a subscription. With a subscription, you pay to get access to content from the app or service.

Some subscriptions automatically renew unless you choose to cancel them. These include:

• In-app subscriptions for content or services (HBO NOW, Spotify, Pandora, Hulu, etc.)
• Apple Music and Apple News+
• Apple TV channels

If you're not currently signed in with the same Apple ID that you use with the subscription that you want to manage, if you're using a different device, or if you don't see your subscription, follow the directions below.
