You can stop Google Play from charging you for AI Mirror after a free trial by canceling your subscription before the free trial ends. Here are the steps to do that:

  1. Open the Google Play Store app on your device.
  2. Tap the menu icon (three horizontal lines) in the top left corner of the screen.
  3. Tap "Subscriptions".
  4. Look for the Go Launcher app and tap on it.
  5. You will see the option to cancel.

It is important to note that if you do not cancel your subscription before the free trial ends, you will be charged for the app. If you have any doubts about the app, you can check the app's page in the Play Store for more information on the free trial and any charges that may apply. Additionally, if you have any questions about your Google Play account, you can contact Google Play's customer support for assistance.
