ZenFox does not collect, transmit, sell or share any personal data.

• No servers, accounts, analytics or tracking: ZenFox never sends anything to its developer or to any third party.
• Local storage only: Workspaces, Essentials, pinned tabs, routing rules, settings, Recently closed and snapshots are saved with Firefox's extension storage inside your own Firefox profile, on your device. They are removed when you uninstall ZenFox.
• Private windows: Addresses and titles of tabs in private windows are never written to disk.
• Website icons: When you choose a website's icon for a workspace, Firefox loads that icon directly from the website you chose, like any page would. ZenFox does not contact any other service.
• Search: Searches you type in ZenFox go to the search engine you chose in Firefox's settings, exactly as if you had typed them in the address bar.
• Optional permissions: Access to all websites is only requested if you enable the on-page shortcut fallback, and is used only to listen for those keyboard shortcuts. Page content is never read.

Questions: contact the developer through the support link on the add-on's page.
