PRIVACY
POLICY
YT EduFocus is a browser extension that helps you learn on YouTube without distractions. Privacy is not a feature — it is the foundation of how this extension was built.
1 What Information We Collect
✅ We collect absolutely nothing.
YT EduFocus does not collect, transmit, sell, or share any personal data. This includes but is not limited to:
- Your watch history, search history, or browsing activity
- Any personally identifiable information (name, email, IP address)
- Device identifiers, browser fingerprints, or location data
- Interaction patterns, click data, or telemetry of any kind
- Video titles, URLs, or timestamps of videos you watch
- Notes content or Watch Later list contents
2 Local Data Storage
YT EduFocus saves your settings and content using chrome.storage.local. This stores data exclusively on your device and is never synced or transmitted to any server.
| Key | Type | Purpose |
|---|---|---|
focusMode | Boolean | Whether Focus Mode is active |
autoFocus | Boolean | Auto-enable on educational videos |
hideComments | Boolean | Whether comments are hidden |
dimUI | Boolean | Whether distracting UI is dimmed |
siteBlocker | Boolean | Whether homepage/shorts blocking is on |
trustedChannels | Array | Channel names you've whitelisted |
watchLater | Array | Videos you've saved to Watch Later |
notes | Object | Your per-video notes (local only) |
studyTime | Object | Daily study time in seconds (local only) |
streak | Object | Your current learning streak |
You can clear all of this data at any time by uninstalling the extension, or by clearing extension storage in Chrome's settings.
3 Network Requests
When Focus Mode is active, YT EduFocus makes one type of outbound network request: an anonymous search query to youtube.com/results to populate the educational suggestions sidebar.
- The request goes directly to YouTube (Google) — not to any YT EduFocus-controlled server
- It is made with
credentials: 'omit'— your YouTube login cookies are explicitly excluded - It is functionally identical to opening YouTube in a private tab and typing a search
- We do not log, intercept, store, or observe this request in any way
4 Permissions Explained
YT EduFocus requests only the permissions strictly required to function:
| Permission | Reason | Data accessed |
|---|---|---|
storage |
Save toggle preferences and notes on your device | Only the keys listed in Section 2 |
scripting |
Detect YouTube video category for educational classification | Page-level JS variable — read-only, discarded immediately |
notifications |
Alert when a Pomodoro session ends or a study milestone is reached | None — only fires when you start a session |
tabs |
Inject content script into open YouTube tabs without requiring a page reload | Only queries youtube.com tabs. No URLs or history stored. |
host: youtube.com |
Run content scripts on YouTube watch pages | YouTube page DOM (read-only) and anonymous search requests |
We do not request: history, cookies, identity, browsingData, webRequest, or any other sensitive permission.
5 Third-Party Services
✅ None whatsoever.
YT EduFocus does not integrate with any third-party service. Specifically, there is no:
- Google Analytics or any equivalent analytics platform
- Error monitoring or crash reporting service (e.g. Sentry)
- Advertising network of any kind
- A/B testing or feature flag service
- External CDN for JavaScript libraries
The extension is entirely self-contained. Every file that runs is bundled in the extension package you downloaded from the Chrome Web Store.
6 Remote Code
YT EduFocus does not fetch or execute any remote code. Every line of JavaScript that runs is bundled inside the extension package and reviewed by the Chrome Web Store before publication.
The educational sidebar fetches YouTube's search results page as data (not code) and parses it as JSON. This is equivalent to your browser loading a normal webpage. No code is evaluated or injected from external sources.
7 Children's Privacy
YT EduFocus does not collect any personal information from anyone, including children under the age of 13. Because no data is collected at all, the extension is inherently compliant with COPPA (Children's Online Privacy Protection Act) and similar international legislation.
8 Changes to This Policy
If we make material changes to this privacy policy, we will update the "Last Updated" date at the top of this page and note the changes in the Chrome Web Store update release notes.
Given that we collect no data, it would be very unusual for this policy to require substantive changes.
9 Contact
If you have any questions about this privacy policy or the YT EduFocus extension, you can reach out via the Chrome Web Store support tab or by opening an issue on the project's GitHub repository.
We are committed to responding to all privacy-related inquiries within 5 business days.
