Apple has inadvertently revealed an in-app subscription option for iTunes. A change to the software's terms and conditions exposes the feature. "A new 'In-App Subscriptions' section has been added to the Terms and Conditions to explain how in-app subscriptions auto-renew, how the auto-renewal can be managed and turned off, and that we may request permission to provide personal information to the Licensor for marketing purposes which, if declined, will not affect your purchase."
