What CleoSum Does

CleoSum is a Chrome extension that analyzes YouTube video content using AI. When you click "Analyze" or "Summarize" on a video thumbnail, we process the video's publicly available transcript to generate insights.

Data We Collect

• Google Account Info: Email, name, and profile picture for authentication (via Google Sign-In).
• Video Transcripts: Publicly available YouTube captions are sent to our server for AI processing. We do NOT store raw transcripts.
• Analysis Cache: Generated analyses/summaries are cached by video ID (not user ID) to serve future requests faster.
• Usage Counts: Daily/monthly request counts for rate limiting.

Data We Do NOT Collect

• Your browsing history
• Which videos you watch
• Your YouTube account data
• Any personal content or messages
• Cookies from other websites

Third-Party Services

• Anthropic (Claude AI): Processes transcripts for analysis. Privacy Policy
• Firebase (Google): Authentication and data storage. Privacy Policy
• Stripe: Payment processing. Privacy Policy

Data Retention

Cached video analyses are stored for 7 days, then automatically deleted. User accounts can be deleted upon request.

Your Rights

You can request deletion of your data by emailing vladislav.babushkin97@gmail.com. You can uninstall the extension at any time to stop all data collection.
