Is Datalayer Checker safe?
Datalayer Checker reads page dataLayer events on visited sites and saves selected snapshots locally.
When installed, its content script runs on HTTP and HTTPS pages, injects a page script that watches window dataLayer pushes, and forwards those events to the extension UI. The popup displays the active tab's dataLayer details and can save user-selected snapshots in chrome.storage.local for later comparison. Stored analysis notes product analytics to umami.datalayerchecker.com for extension version and usage metrics, not captured dataLayer contents.

Where it sends data
Destinations our analysis observed Datalayer Checker contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
