FocusFence - Website Blocker does not collect, transmit, sell, or share any user data. Period.
All information you enter into the extension — your website groups,
schedules, break settings, and strictness options — is stored locally
in your browser using the browser's built-in extension storage
(chrome.storage.local). This data never leaves your device.
The extension has no servers, no accounts, and no analytics.
If you set a group password, only its SHA-256 hash is stored, locally, in your browser. Passwords themselves are never stored, transmitted, or recoverable by us or anyone else.
The extension processes page URLs in memory, on your device, solely to compare them against your own block/allow lists. It does not record your browsing history, does not track you, and does not send any browsing information anywhere.
There are none. No analytics SDKs, no advertising, no remote code, no data transmission of any kind.
