What data we collect

LikePulse does not collect, store, or transmit any personal data. The extension operates entirely within your browser.

YouTube Data & Comments

When you click "Analyze this video", LikePulse fetches public comments via our secure Cloudflare Worker proxy, which calls the YouTube Data API v3. Only the video ID is sent — no personal data or account information.

AI Analysis

When AI analysis is requested, a summary of public comments and the video's public transcript is sent to our Cloudflare Worker, which calls the Anthropic API (Claude Haiku). No user identifiers are included. Your personal data is never part of these requests.

Amazon Affiliate Links

When AI detects products in a video, LikePulse may show Amazon links with affiliate tags. Clicking them may earn us a small commission at no extra cost to you. We do not track clicks beyond Amazon's standard affiliate program.
