The AirConsole Hero subscription is linked to and managed directly by the App Store account (Apple, Google, Huawei and Amazon). AirConsole does not have access to users' payment information in their personal accounts, and can therefore not cancel a subscription for you.
To manage and cancel subscriptions, please read the corresponding guide:
A subscription can always be cancelled, but please note that a subscription will automatically renew itself 24h before ending. If this deadline is missed, the subscription will automatically be renewed for another period (according to your subscription) and the cancellation will only take place after this new period.
