Privacy Policy — YT Kids Guard

Last updated: March 12, 2026

1. What YT Kids Guard Does

YT Kids Guard is a Chrome browser extension that helps parents manage their children's YouTube usage. It provides daily watch time limits, channel allow/block lists, and Shorts blocking — all controlled by a parent password.

2. Data We Store Locally

All data is stored only on your device using Chrome's built-in storage APIs. Nothing is sent to any external server unless you explicitly opt into cloud sync (see Section 3).

chrome.storage.sync (synced across your Chrome profile, on your Google account):

• Parent password hash (SHA-256, salted — the actual password is never stored)
• Daily watch time limit setting
• Allowed channels list (channel names and handles)
• Blocked channels list (channel names and handles)
• Shorts blocking preference and filter mode
• Extension enabled/disabled state

chrome.storage.local (device only, not synced):

• Daily watch time counter (total seconds used today — resets at midnight)

3. Optional Cloud Sync

If you choose to create a family account at yt-blocker-kids.vercel.app, your settings will be synced to our backend (Convex). In that case:

• Your email address is stored for account authentication
• Your extension settings (timer, channel lists) are stored server-side so you can manage them from your phone
• No YouTube viewing history, video data, or personal browsing data is ever transmitted

Cloud sync is entirely optional. The extension works fully offline without it.

4. Permissions Explained

Permission	Why It's Needed
tabs	Detect when a YouTube tab is active to track watch time accurately
storage	Save parental settings and the daily watch time counter
alarms	Check watch time every minute and reset the counter at midnight
activeTab	Read the current YouTube channel name when the popup is opened
scripting	Inject the content script that shows overlays and manages channel filtering on YouTube
sidePanel	Allows the settings panel to open as a browser side panel
Host: *.youtube.com	The extension only runs on YouTube — no other site is accessed
Host: *.convex.cloud	Used only when optional cloud sync is enabled, to communicate with the family dashboard backend

5. Data We Do NOT Collect

• Browsing history (on YouTube or anywhere else)
• Video watch history or titles
• Search queries
• Usernames or Google account details
• Device identifiers, IP addresses, or location
• Any information from websites other than YouTube

6. Children's Privacy

This extension is designed for families with children. The daily time counter stores only a total-seconds count and the current date. It does not record which videos or channels were watched. No child-identifiable information is collected or stored.

7. Password Security

• Passwords are hashed with SHA-256 before storage — the plaintext password is never saved
• Brute-force protection: 5 failed attempts trigger a 60-second lockout

8. Data Deletion

All local data is removed when you uninstall the extension from chrome://extensions/. If you created a family account, you may request deletion by contacting us at the email below.

9. Third Parties

We do not sell, share, or transfer any user data to third parties. No analytics SDKs, ad networks, or tracking scripts are included in this extension.

10. Changes to This Policy

If this policy is updated, the new version will be published here with an updated date. We will never introduce data collection without explicit user consent.
