1Blocker 4.0: Now with In-App Tracker Blocking

Today we are releasing 1Blocker 4.0, a major update that introduces in-app tracker blocking and the new privacy protection overview tab.

Firewall is a new feature that allows you to protect your privacy not only in Safari but in all apps on your iOS device. It can automatically block more than 9,200 in-app trackers, including spy pixels in emails, behavior measurement trackers, and other analytics services.

What makes our approach different is that 1Blocker performs all the blocking on your device only and doesn’t collect any of your data. Your internet traffic is not routed through any servers. That makes our solution super fast, and you won’t notice any slowdowns.

Firewall runs in a network extension on iOS and acts as a local proxy or gateway between you and the internet. When it sees a request is being sent to a block-listed host, the extension just drops the connection. Other requests stay untouched and work just like before.
