Note: Uninstalling an app will not automatically stop your subscription. You must cancel your subscription to end your subscription. If you uninstall the app without canceling your subscription, you will still be charged. If an app you've purchased a subscription for is removed from Google Play, your future subscription will be automatically canceled but past subscriptions will not be refunded.
