Why this isn't good enough

LockedWeb for Chromebook is coming soon. Today it protects iPhone, iPad, Android, Windows and Mac.

Hole: Whoever can edit network settings can change the Chromebook's DNS back in seconds, and that gives full access again.

Every LockedWeb device: Waits 72 hours before protection loosens, then needs a one-time code.
Hole: Nobody would know. There's no alert and no report, so no parent or accountability partner would have any way of knowing.

Every LockedWeb device: Shows its protection status in the dashboard, and can alert an optional contact if someone asks to loosen protection or if protection is tampered with or removed.
Hole: Only the Wi-Fi networks you set it on. School, a café or a hotspot isn't covered.

Every LockedWeb device: Protected on any network.

Questions and troubleshooting

School Chromebooks, ChromeOS Flex, Android apps, the test address

It is a school or work Chromebook: Its administrator sets the policies, and your changes may be blocked or reset. Ask them, and bring the device model, the account you sign in with and what you want filtered.
It runs ChromeOS Flex: Flex runs ChromeOS on Windows and Mac hardware and differs from Chromebooks in some features. Run the checks above before you rely on a setup.
You use Android apps or Linux on it: Run the same check inside them too.
Cloudflare's test address still opens: Check the two addresses on the network you are using, then reopen Chrome.
Which account to check: The one the person actually signs in with. For a child, that is their supervised Google Account.
