Works independently: no mobile app or NFC accessory is required. Phone synchronization is not included in this version.
Blocking applies to websites in the Chrome browser where this extension is enabled. Other browsers and apps are not affected. Incognito requires separate permission in Chrome settings.
The extension does not collect page content or Chrome browsing history and includes no advertising or analytics SDK. Settings, modes, and schedules may sync according to your Chrome sync settings. Session records stay on your device. Original blocked URLs are used temporarily on the local blocked page to reopen a site after restrictions end; they are not sent to the developer.
