Privacy Policy
What the extension reads
To detect Meta Pixel scripts on a webpage, the extension reads the following from pages you visit while it is enabled:
- The presence and source URL of
<script>tags pointing toconnect.facebook.net - Browser performance entries for requests to
www.facebook.com/tr(the standard Meta Pixel tracking endpoint) - Open Graph meta tags, JSON-LD blocks, and the page meta description — all publicly visible page metadata
These reads are performed locally by JavaScript running inside your browser. The extension makes no outbound network requests of its own.
What the extension stores locally
The following is stored on your own device using chrome.storage.local and never leaves your computer:
- A list of Meta Pixel IDs detected on sites you have visited, with the timestamp they were last seen and the hostname (e.g.
example.com) where they were detected. This powers the optional stale-pixel warning feature. - Your settings — which features you have toggled on or off in the Options page.
You can clear this data at any time from the Options page using the Clear tracked pixels button.
What the extension does NOT do
- Does not send any data to the developer or any third party
- Does not include analytics, tracking SDKs, or telemetry
- Does not read page content beyond Meta-Pixel-related script tags and metadata
- Does not access cookies, browsing history, passwords, or form inputs
- Does not modify the pages you visit
- Does not display advertisements
- Does not sell, share, or transfer any user data
