Subscriptions for Google account holders are managed from within the Google Play application
How to cancel:
- Open the Google Play Store
- Tap Menu AccountSubscriptions.
- Find the subscription you want to cancel.
- Tap Cancel.
Important: Uninstalling a game will not automatically stop your subscription. You must also cancel your subscription to end your subscription. If you uninstall the game without also cancelling your subscription, you will still be charged.
If you cancel the subscription during the initial trial period (7 days) you will not be charged, otherwise (if after 7 days) you will continue to have access to all of the subscription features until the end of your current subscription period.
