Privacy Policy for YouTube Misinformation Detector

1. Core Commitment: Privacy by Design

The YouTube Misinformation Detector Chrome Extension is built with a strict privacy-first foundation:

• No Account Required: You do not need to register or log in.
• No Tracking or Profiling: We do not monitor your personal browsing habits, watch history, or create user profiles.
• Zero Data Monetization: We never sell, rent, or trade your data with advertisers, third-party brokers, or data syndicates.

2. Information We Process

When you browse a YouTube watch page (youtube.com/watch?v=...), the extension interacts solely with:

• YouTube Video Identifier: The public 11-character video ID from the URL (e.g. dQw4w9WgXcQ) is sent to our fact-checking backend to query public video captions.
• Current Video Playback Time: Evaluated strictly in local browser memory to align warning overlay cards with spoken sentences.

We do NOT collect: Personal identities, email addresses, Google account credentials, browsing history outside YouTube watch pages, location data, or payment information.

3. Local Storage

All user customization preferences (such as enabling/disabling the overlay or active verdict filters) are stored locally on your device via Chrome's chrome.storage.local API and never leave your browser.

4. Third-Party Services

Public transcripts are analyzed for factual accuracy using Google Gemini AI models through our secure backend API. No user-identifiable data or cookies are transmitted to third-party AI APIs.

5. Developer Program Certifications

In accordance with the Google Chrome Web Store Developer Program Policies:

• We do not sell user data to third parties.
• We do not use or transfer user data for purposes unrelated to the extension's core functionality.
• We do not use or transfer user data for creditworthiness or lending purposes.
