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
In plain English: We don't know who you are, what you watch, or how you use the extension. We have no way to know — and we designed it that way intentionally.

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.

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
Google's privacy policy applies to all requests made to YouTube. See policies.google.com/privacy.

4 Permissions Explained

YT EduFocus requests only the permissions strictly required to function:

PermissionReasonData 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.
