Is X Pixel Helper safe?

X Pixel Helper detects X (Twitter) advertising pixel tags on visited pages and displays their parameters locally.

The extension monitors network requests to analytics.twitter.com and analytics.x.com to identify X pixel events fired by websites. When a pixel event is detected, it reads the page referrer and captures event parameters — including any email or phone number fields that advertisers pass to the pixel — and stores them locally via chrome.storage for display in the popup. No data is sent to any remote server; all captured pixel details remain on the user's device.
