A Google Account, not a birthday, runs Family Link

The short answer

Family Link is Google's supervision layer for a child's own Google Account, not a separate monitoring app bolted onto an adult's phone. It lets a parent approve apps, set daily or bedtime limits, and see roughly where a linked device is, because the account itself carries the supervision, across whichever device is signed in.

What the evidence says

Google's Family Link product page, as retrieved on 16 September 2026, describes an account created for a child under 13, or the applicable local age, through which a parent can set daily time limits with School Time and Downtime schedules, apply per-app limits while leaving selected educational apps unlimited, and require approval before a new app installs from Google Play. Google's help centre article on getting started, also current as retrieved, confirms the same under-13 threshold and adds that a parent can block or permit specific app permissions and see device location through Family Link or a linked Fitbit.

Supervision is not indefinite by design. A further help article on creating a child's account states that a child, once above 13 or the applicable age in their country, can stop supervision at any time, at which point the parent is notified and the child's supervised devices are temporarily locked. The article points to a further resource on what happens to the account specifically when a child turns 13, without repeating those mechanics itself.

For context

Family Link supervises a Google Account, not a child's entire digital life. A browser session, an app store on a different platform, or a device signed into a different account sits outside what Family Link can see or limit. The 'applicable age' wording also matters: Google ties the exit from supervision to each country's legal digital age of consent rather than one global number, so the age at which a child can end supervision differs by where the family lives, and the documentation does not commit to a single figure.

A practical next step

Rather than treating 13 as a hard cutoff everywhere, you could check what your own country sets as the digital age of consent before assuming supervision will end, or can be renegotiated, at exactly that age.

• Which apps or services does your child use outside their Google Account, where Family Link has no visibility?
• Do you know the digital age of consent in your own country, and how close your child is to it?
• What happens in your household when supervision ends: is it a single event, or a planned conversation?

The documentation is precise about the mechanics it controls and quiet about everything else, which is itself useful: a family account is a scoped tool, and knowing its edge matters as much as knowing what it restricts inside that edge.
