Here's how you can cancel your subscription on Google Play:
- Launch Google Play with the same email that you use for your WeParent account
- Tap on the hamburger menu in the upper left
- Tap on "Subscriptions". From there, you can see all of your current subscriptions and cancel the ones you don't want.
- Find the WeParent subscription, and cancel it.
This also works if you want to cancel your Free Trial.
