How can I cancel the subscription?

Users can only cancel a subscription in the settings of their Google Account, as we don't have access to it and are not authorized to manage subscription cancellations or changes. Please follow these steps to cancel your plan:
1. On your Android phone or tablet, open the Google Play Store.
2. Check if you’re signed in to the correct Google Account.
3. Tap Menu and then Subscriptions.
4. Select the subscription you want to cancel.
5. Tap Cancel subscription.
6. Follow the instructions.
 

Alternatively, you can go to the app Settings and tap on Subscriptions. You will be automatically redirected to the tab with subscriptions in the store, where you can cancel the plan. 

Here are also the instructions provided by Google Play Help on how to cancel the subscription.

! Please note that subscriptions must be canceled at least 24 hours before the next billing cycle to avoid being charged for the next period of use. Once canceled, your plan and access will remain active until your current billing period ends.
