Is SiteBlock safe?

Low risk

SiteBlock redirects visits to blocked sites to a hosted block page at not-today.gadfaria.com.

When SiteBlock is enabled, it checks tab URLs against the sites saved in its block list. Matching visits are redirected to a remote hosted block page, so that page receives the browser's request instead of the blocked site. The blocked URL is not added to the redirect URL.

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

Where it sends data

Destinations our analysis observed SiteBlock 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.
