Google Will Infer Users’ Ages in Canada to Apply Teen Safety Settings

Google will gradually roll out age-assurance technology in Canada in the coming days, using machine learning to estimate whether an account belongs to someone over or under 18. Accounts identified as belonging to minors will automatically receive Google’s existing enhanced protections.

The system draws on signals already associated with a user’s account. Google says those signals include the types of information a person searches for and the categories of YouTube videos they watch. The company says its model does not collect new information beyond data already linked to the account.

Google describes those signals as a way to determine whether someone is likely over or under 18. It says it will alert people its tools estimate might be younger than 18, rather than asking every user to supply new age information.

Google says it will notify people estimated to be under 18 by email and while they use its products. Those notices are meant to explain which default settings changed and how an adult can correct an incorrect estimate.

The age estimate is not limited to a single Google service. For accounts the company recognizes as minors, it says the rollout will apply a package of existing safeguards designed to create more age-appropriate experiences.

• YouTube will turn on break and bedtime reminders and limit repetitive views of some content through recommendation safeguards.
• Google will disable Maps Timeline, stop personalized advertising and restrict age-sensitive advertising categories.
• Google Play will block apps that are restricted to adults.

Google describes the rollout as a combination of age estimation and privacy-protecting age verification when verification is needed. It argues that age assurance should remain the responsibility of individual service owners, rather than a universal age arbiter, because each developer, publisher and app creator knows its services and users best.

That position puts the practical tradeoff inside each platform: Google aims to apply protections without requiring every user to provide new age information, while offering a way to challenge an estimate. The rollout’s immediate consequence is that account activity can determine which safety settings apply to Canadian users across several Google products.
