Why do I get charged for google play?
It seems that I get charged for every game or google play. Why isn’t this free?
iPhone 6, iOS 12
It sounds like you have some subscriptions going. Often after a free trial those automatically change to pay services.
View, change, or cancel your subscriptions - "Learn how to view your subscriptions that renew automatically, change your subscription period, and turn off Automatic Renewal." "If you don’t cancel more than 24 hours before your renewal date, your subscription might renew." https://support.apple.com/HT202039
