Once you have activated a free trial through Google Play store, you will need to cancel at least 24 hours before the trial period ends to avoid being charged for the annual subscription.
Note: You will need to cancel through the Google Play store settings on your device.
1. Open the Google Play store app on a mobile Android phone or tablet.
2. Tap the menu button in the top left corner of the Google Play store app (3 horizontal lines).
3. In the side menu that appears, click on the Subscription option.
4. Tap the Good Vibes free trial subscription that is listed there.
If you do not see Good Vibes listed, this means you do not have a free trial activated on this Google Play account.
5. Tap the 'Cancel subscription' option and follow the on-screen instructions to confirm cancellation.
