Does deleting my account also cancel my active subscription?
No. Deleting your account does not cancel your subscription. You need to cancel them separately.
1.First, cancel your subscription
Cancel where you bought: App Store (Apple Subscriptions), Google Play (Google Play subscriptions), or Paddle. See How do I cancel my subscription?.
2.Then, delete your account if you still want to
If you delete your account without canceling first, you’ll keep being charged until the subscription expires. Deleting is permanent: your data, lesson history, and progress can’t be recovered. See How do I delete my account?.
