Effective August 18, 2026.

This policy explains how the Fokasu browser extension handles information while providing focus-session website blocking.


While an active Fokasu focus session is enforcing website blocks, the extension reads open-tab URLs locally so it can compare them with the user's configured block and exception patterns. Matching pages are redirected to the extension's blocked page.

The extension does not send tab URLs, browsing history, page contents, page titles, cookies, credentials, form data, or search terms to Fokasu's remote services. It does not build or retain a browsing-history database.


The extension communicates with the Fokasu desktop application running on the same device through a localhost connection.

The desktop app sends the user's block rules, exception rules, and focus-session state to the extension. The extension sends a small local heartbeat containing the browser family, whether a private window is open, whether private-window access is enabled, the extension ID, and a timestamp.

This technical information is used only to maintain the website-blocking connection between the extension and the user's desktop application. It is not sent to advertising platforms, data brokers, or unrelated third parties.


Fokasu uses this information only to provide, maintain, and secure its focus-session website-blocking feature.

Fokasu does not sell this information, use it for personalized advertising, or share it with advertising platforms, data brokers, or unrelated third parties.

Consent choices and settings needed to provide browser protection may be stored locally by the extension. They do not contain visited-page history.


If the user enables private-window access, Fokasu can enforce the same blocking rules in private windows. The extension does not save or transmit private-tab URLs. The same privacy protections apply in private windows.


On first run, users can decline the local desktop-app connection instead of granting consent. Users may remove the extension, disable private-window access, or stop using the Fokasu desktop application.

Removing the extension removes its locally stored extension data.
