Everything you need to protect your family

Installation

Installing on Windows

Child Web Guard comes as one Windows installer — get it from the download page and run it on your child's PC. Protection appears in Chrome and Edge the next time the browser opens, and a small background app keeps it in place. There is nothing to add from the Chrome Web Store — the installer takes care of everything.

System Requirements

Configuration

AI Providers

Child Web Guard supports three AI providers. All use OpenAI-compatible APIs:

• Qwen (Aliyun) — Default. Endpoint: maas.aliyuncs.com. Model: qwen3.7-plus
• Kimi (Moonshot) — Endpoint: api.kimi.com. Model: kimi-k2.7
• z.ai (GLM) — Endpoint: api.z.ai. Model: glm-5.2

Blocking Rules Priority

Rules are evaluated in this order (first match wins):

AI Classification

When an unknown site is visited, the extension sends the page title and content (truncated to 3,000 characters) to the AI provider. The AI returns a JSON verdict:

{
  "category": "gaming",
  "tags": { "gaming": 93 },
  "language": "English",
  "reason": "This is a gaming platform"
}

Custom Rules

Add plain-text rules in the dashboard that shape AI decisions:

# General rules (apply to all sites)
No content about pranks or challenges
Allow math puzzle games

# Domain rules (apply only when domain matches)
scratch.mit.edu: kids may create projects,
  but playing others' games is blocked

YouTube Protection

YouTube has three modes:

Channel Blocking

Add YouTube channel handles (e.g., @guagua883) to the blocked channels list. Videos from these channels are blocked regardless of AI verdict.

Escalation System

When 5 or more subdomains of the same registered domain are blocked (e.g., foo.itch.io, bar.itch.io), the domain is escalated for parent review.

In the dashboard Escalated Domains tab, you can:

• Allow this domain — Clears the escalation. The domain will no longer be auto-blocked.
• Keep blocked — No action. The domain remains blocked.
• Add to whitelist — Go to Settings and add the domain to the whitelist for permanent allowance.

Activity & Screen Time

The extension keeps a local activity record in each browser (every browser and browser profile has its own) so you can see how it is used. Open it from the extension popup → Known sites on this device (PIN required) → Activity in this browser. You will find:

• Today's numbers — screen time, safe visits, AI checks, and blocks.
• 7-day screen-time chart — active browsing minutes per day.
• Top sites and categories — where the time goes and what kind of content is viewed.
• Recent activity — pages visited with allowed/blocked outcomes.

Privacy is built in, not bolted on: the record never leaves the computer (not uploaded, not synced, not in the web dashboard), the page list auto-deletes after 7 days, and your child can see their own daily summary in the extension popup. You can pause counting or erase the record at any time from the same device page.

Desktop Agent (Windows)

The Desktop Agent is a small Windows program that keeps Child Web Guard in place. It installs automatically with everything else — and it's the reason your child can't remove or disable the protection.

What It Enforces

• Keeps protection installed in every Chrome and Edge profile — even if your child tries to remove it
• Turns off Incognito/InPrivate mode, so browsing can't be hidden
• Blocks guest mode and new browser profiles — two common bypass tricks
• Disables developer tools
• Checks itself every 30 seconds and re-applies protection if anything was changed

Installation

Nothing separate to install — the Desktop Agent is included in the installer from the download page and starts automatically with Windows.
