Meta Pixel Tester is a browser extension that shows the Meta Pixel events a website sends from your browser and checks them for problems.
What the extension reads
While you browse with the extension installed, it looks at the requests pages send to Meta's pixel endpoint and the fbq calls the page makes. From these it reads event names, parameters, pixel IDs, the page address and whether certain first-party cookies exist. It does not read passwords, form contents or other page content.
What is stored
Captured events and page groups are stored in your browser's extension storage on your device. Email addresses and phone numbers found in event parameters or page addresses are replaced with placeholders before saving. Customer fields are saved only as field names with a note on whether they were hashed. Your settings (theme and alerts) are stored the same way.
How long
Events are deleted automatically after 7 days. You can clear one site or all history at any time from the side panel.
What is shared
Nothing. The extension makes no network requests of its own, has no servers, no accounts, no analytics and no advertising. No data is sold or transferred.
Notifications
If you turn on error alerts, the extension shows local desktop notifications. They are created on your device and nothing is sent anywhere.
This website
This website uses no tracking or advertising cookies. Your browser stores one value to remember that you closed the cookie notice.
Children
The extension is a developer tool and is not directed at children.
Changes
If this policy changes, the new version will be published on this page with a new date.
