Is MyAdFilter safe?

Low risk

MyAdFilter sends the full URL of pages on vendor-listed sites, with ad counts, to api.poc.myadfilter.com.

On sites matching a publisher list fetched from the vendor's backend, the extension hides ad elements and periodically sends the page URL, including any query string, plus blocked and allowed ad counts to the vendor. It logs in to that backend with a username and password stored in the extension's code. A first-run page can also offer to uninstall competing ad blockers when the user clicks a button, and reports that to the vendor.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Where it sends data

Destinations our analysis observed MyAdFilter 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.
