Karo Website Shield
Block distractions only when focus needs protecting.
Karo Shield redirects the websites you choose while a Focus or Custom timer is running. Matching happens locally in the browser extension.

Timer-connected protection
Manual shield when needed
No browsing-history collection
A deliberately small blocklist
Karo begins with no blocked websites. Add only the domains that regularly pull you away from the work you intended to do.
Connected to real focus
The shield can activate automatically for Focus and Custom sessions, then stand down when the session finishes. Matching sites that are already open are redirected immediately. A manual mode is available for unstructured work.
Private by design
The extension compares requested and currently open tab addresses with the locally saved blocklist. Open-tab checks happen locally when the shield activates or its active blocklist changes. Karo does not read page content, build browsing profiles or send browsing history.
