Reviewing and canceling subscriptions associated with your Google Account is a simple process. Please follow these steps:

1. Open a web browser and go to the Google Play Store website.

2. Sign in to your Google Account if you haven't already done so.

3. Click on your profile picture or initial in the top-right corner of the screen and select "Payments & subscriptions" from the dropdown menu.

4. In the "Subscriptions" tab, you will find a list of all active subscriptions linked to your Google Account.

5. To review a subscription, click on it. You will see detailed information about the subscription, such as the renewal date and price.

6. To cancel a subscription, click on the "Cancel subscription" button next to the subscription details. Follow the on-screen instructions to confirm the cancellation.

7. After canceling a subscription, you will no longer be charged, and your access to the subscription's content or features will be terminated at the end of the current billing cycle.

Please note that canceling a subscription does not provide a refund for any unused portion of the subscription. It only prevents further charges from occurring.

If you have subscribed to a service or app outside of the Google Play Store, you will need to manage your subscriptions directly through that service or app. Instructions for managing subscriptions should be provided by the respective service or app.
