Is AdGuard Browser Assistant safe?

Clean risk

This extension adds in-browser controls for the AdGuard desktop app’s site filtering and element blocking.

It lets you turn ad blocking on or off for the current website, manually remove page elements, and delete user rules related to a page. It also provides access to AdGuard desktop app settings and the filtering log for the page, and includes an option to report a site when an ad appears. The AdGuard desktop app for Mac or Windows is required.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
