Handing a child their first phone also hands them an app store, the open web and unlimited screen time. Google's free Family Link app lets you manage all of that from your own phone: the apps your child wants land on your screen for approval, the device locks when the daily limit runs out, and filters kick in on Chrome and Google Search.
In Türkiye a child cannot manage their own Google Account until they turn 13, so a parent creates and supervises the account for younger children. If your child already has an account, supervision can be added to it with their agreement.
This guide covers the whole setup: requirements, creating or linking the account, app approvals, screen time, content filters, location and what happens when your child turns 13.
