What data we collect

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

YouTube Data API

When you click "Analyze this video", LikePulse fetches public comments for that video using the YouTube Data API v3. This data is processed locally in your browser and is never sent to our servers.

AI Analysis

When you request an AI analysis, a summary of public comments (not personal data) is sent to our Cloudflare Worker, which calls the Anthropic API to generate the analysis. No user identifiers are included in these requests. Results are cached for 7 days by video ID only.

Amazon Affiliate Links

LikePulse may display Amazon product links with affiliate tags (adriancubasre-20 for US, adriancubasal-21 for ES). Clicking these links may earn us a small commission at no extra cost to you. We do not track clicks beyond what Amazon's standard affiliate program provides.
