Setup & support
Email trifocal.store@gmail.com for help or privacy requests. Include your Chrome version and what you were trying to do. Never send passwords or PINs by email.
10-minute setup
- Install Parent Shield from the Chrome Web Store on the child's Chrome profile.
- Open the extension icon and set your 4–6 digit parent PIN.
- In Settings, confirm the daily limit, bedtime window and any extra blocked sites. Save.
- Test it: open an AI chat site, wait for the launcher state, and try "Pause AI chats now" from the popup — the lock screen should appear until you enter the PIN.
Covering "everything else" — the free DNS layer
No extension can know every harmful site or image — anyone claiming that is lying. For million-domain coverage (including phones, apps and games), add a free family DNS filter: create a free account at NextDNS.io or Cisco's OpenDNS FamilyShield, enable the parental preset, and apply it on your router or each device. Layered together: DNS filter (whole home) + Parent Shield strict list & SafeSearch lock (browser) + supervised profile (can't uninstall) = the strongest practical setup.
Making it stick (younger teens)
Use a supervised Chrome profile via Google Family Link on the child's account. Supervised profiles let a parent force-install extensions the child cannot remove or disable. On an unsupervised profile, a determined teen can uninstall any extension — Parent Shield included.
What gets filtered
Explicit sexual, violence and drug content in AI replies is blurred with a label. Self-harm language triggers a crisis banner with helpline resources (US: call/text 988; worldwide directory: findahelpline.com). General school or hobby chats are not filtered.
Common issues
- No filtering on a site: the site may not be covered yet — add it to the block list if you want it fully paused, and email us to request coverage.
- Lock screen at the wrong time: check the bedtime window and device clock in Settings.
- Forgot the PIN: for safety there is no backdoor. Removing and reinstalling the extension resets settings (events and usage are cleared).
Parent Shield is a support tool for families, not medical or psychological care. If a young person is in danger, contact emergency services or a crisis helpline immediately.
