You can cancel your KineMaster Premium subscription by following these steps:
1. Open the Settings app
2. Tap on your Apple ID
3. Tap Subscriptions >> KineMaster >> Cancel Subscription.
When you cancel a subscription, you’ll still be able to use your subscription for the time you’ve already paid for.
Note: Uninstalling KineMaster will not cancel your subscription. Should you uninstall KineMaster without cancelling your subscription, you will still be charged— you must actively unsubscribe following the process above.
