Dopamine Guard

Dopamine Guard adds deliberate friction before distracting browsing sessions. For each site you configure, the extension shows a full-page prompt asking how long you want to use that site. When the timer expires, Dopamine Guard closes the session by redirecting matching tabs away from the site and clearing the active timer. Everything runs locally in Chrome. Your blocked domains, default timer length, and active session state stay inside Chrome extension storage. Dopamine Guard does not use remote servers, analytics, advertising, or third-party tracking.
