Chromebooks are increasingly how kids access school — and, often by default, a huge slice of the internet. This guide covers both school-issued and family-owned Chromebooks.
Use the Google account you created via Family Link. If the Chromebook was previously set up with a different account, sign out and remove that account from Settings → Accounts.
Open a Chrome tab, go to google.com → Settings → Search Settings → turn on SafeSearch (Filter). Because the account is supervised, this setting is locked on.
In Family Link: child → Controls → Filters on Chrome. Options: Allow all sites, Try to block explicit sites, or Only allow approved sites. For under-10, allowlist is usually right.
Controls → Filters on Google Play & Chrome Web Store → Parent approval required. Extensions are the sneaky vector here — many "free" ones are trackers.
Settings → Security & Privacy → Manage other people → Restrict sign-in to the following users. Guest mode lets anyone bypass your setup.
Family Link → Screen time. This counts only active Chromebook use, not video-playing-in-background time; tune accordingly.
Same menu → Bedtime. Chromebook locks itself at the bedtime you set, kid or no kid.
chrome://extensions. If you see things you didn't install, they're almost certainly from school. Don't remove them — ask the school what they do if unsure.
At myactivity.google.com, check that Web & App Activity, YouTube History, and Location History are all off for the child account.
