Cancel A Subscription
Uninstalling the app will not cancel your subscription.
- Go to play.google.com.
- Check if you’re signed in to the correct Google Account.
- On the left, click My subscriptions.
- Select the subscription you want to cancel.
- Click Manage
Cancel Subscription.
Also, note that canceling a subscription will stop the recurring fee moving forward, and you will have access to the content until your last payment expires.
Important: Uninstalling the app will not automatically stop your subscription - you must actively cancel the subscription using the process described here. If you uninstall the app but don't cancel your subscription first, you will still be charged.
Cancelling a subscription will not retroactively refund subscription payments, and previously charged subscription fees cannot be pro-rated based on cancellation date. For example, if you purchased a one-year subscription on Jan. 1 for $29.99 and decide to cancel your subscription on July 1, you will have access to the subscription until Dec. 31 and will be charged the full $29.99, but you will not be charged another yearly subscription of $29.99 the following Jan. 1.
