Ingage subscriptions purchased within the app are made via iTunes and, therefore, must be cancelled with Apple (not within the Ingage app). For instructions on how to cancel your subscription, please see this article.
If your subscription purchase was made in error, please report this to Apple here.
Cancelling your subscription will downgrade you to a free Ingage account, which has limitations on the number of stories, number of pages, and types of pages that are available. As a result, some of your content may become inaccessible or non-functional after your cancellation.
If you are considering cancelling, we'd really appreciate it if you would let us know why. Please shoot us a note here.
