Privacy Policy
Last updated: February 21, 2026
Overview
WebBlock is a browser extension that helps users block distracting websites. WebBlock does not require an account and does not sell user data.
Data WebBlock processes
WebBlock processes only the data required to enforce blocking rules chosen by the user, including:
- Website host/domain information needed to match and block sites.
- Usage timing data (for example, active time spent on a site for daily time limits).
- User settings such as block lists, schedules, Tunnel Vision configuration, and cooldown state.
How data is stored
WebBlock stores extension settings and state locally in Chrome storage on your device. WebBlock does not run its own backend service to store your browsing data.
How permissions are used
- declarativeNetRequest: applies dynamic block rules configured by the user.
- storage: saves settings and timer/cooldown state locally.
- alarms: runs scheduled checks, cooldown timers, and daily reset tasks.
- tabs: reads active tab URL/host to enforce rules and track time-limit usage.
- host permissions (<all_urls>): allows blocking of any site selected by the user.
External requests
To display site icons in the popup list, WebBlock may request favicon images from Google's favicon endpoint. This request can include the site domain needed to retrieve the icon.
Data sharing
WebBlock does not sell personal data and does not transfer user data to third parties for advertising or unrelated purposes.
Data retention and control
Your extension data remains in local Chrome storage until you edit settings, clear extension data, or uninstall the extension.
