Family Link is a Google app that can be used to monitor and manage your child’s device usage. The app is available for all Android devices running version 5.0 or higher, as well as iPhones running iOS 7 or higher. Family Link does not have an age limit, but the parent must be 18 years old.
Google does not allow you to change your age. In order to change your age, you will need to change your birth date in the settings of Google+.
To remove a child from Family Link, you will need to log into Family Link and select the “Remove” button next to the child’s name. You can then confirm that you want to remove them from Family Link by entering your PIN.
