  SmartWatch
  Analyze the current YouTube video transcript against your goal with Gemini.
  
  SmartWatch analyzes the transcript of the currently open YouTube watch page against a goal you enter and returns a Gemini-generated analysis in the Chrome side panel.
  
  Open a YouTube watch page, enter a goal, and click Analyze. SmartWatch retrieves the current video's accessible transcript or captions, sends the transcript plus your goal to Google Gemini using your Gemini API key, and shows a concise analysis in the side panel.
  
  Features:
  
  - Analyze the currently open YouTube video against a goal you enter.
  - Get a relevance score, useful insights, suggested next steps, and caveats.
  - Use your own Gemini API key.
  - Choose a Gemini model preset or enter a custom model string.
  - Customize the analysis prompt template.
  - Store your API key, selected model, saved goal, and prompt template locally in Chrome extension storage.
  
  SmartWatch only operates on YouTube watch pages with accessible transcript or caption data. It does not download video or audio, inject ads, sell data, or send data to a developer-operated backend.
  
  SmartWatch is not affiliated with, endorsed by, or produced by Google, YouTube, or Gemini. Use of Chrome, YouTube, and Gemini remains subject to their respective terms and policies.
  
  Privacy And Data Use
  
  When you click Analyze, SmartWatch reads the transcript of the current YouTube video and sends that transcript plus your goal to Google Gemini through the Generative Language API. The extension uses your Gemini API key for that request.
  
  SmartWatch handles these data categories:
  
  - Authentication information: your Gemini API key.
  - User-provided content: your goal and custom prompt template.
  - Website content: transcript text from the current YouTube video.
  - Web browsing activity: whether the active tab is a supported YouTube watch page, plus the current YouTube URL/video ID.
  - Settings data: selected Gemini model and local extension settings.
  
  SmartWatch stores the Gemini API key, selected model, saved goal, and prompt template locally in Chrome extension storage. It does not operate a backend server, sell personal data, share data with advertising networks, use data for personalized ads, or use data for creditworthiness or lending decisions.
  
  Privacy policy: [https://github.com/Evanthel/smartwatch-youtube-analyzer/blob/main/PRIVACY.md](https://github.com/Evanthel/smartwatch-youtube-analyzer/blob/main/PRIVACY.md)
  
  Permissions Justification
  
  - activeTab: reads the active tab context so SmartWatch can confirm the current page is a YouTube watch page.
  - storage: stores your Gemini API key, selected model, saved goal, and custom prompt template locally in Chrome extension storage.
  - scripting: injects the content script when needed so transcript extraction can run on the current YouTube watch page.
  - sidePanel: displays the SmartWatch user interface in Chrome's side panel.
  - webNavigation: keeps side panel availability synchronized as YouTube changes videos through in-page navigation.
  - https://www.youtube.com/ and https://m.youtube.com/: limits transcript detection and extraction to YouTube pages.
  
  Remote Code Declaration:
  SmartWatch does not load or execute remotely hosted extension code. It sends requests to Google Gemini and YouTube endpoints for data needed by the user-facing analysis feature.
