Tab Locker does not collect, transmit or share any personal data.

Everything the extension uses (your goals, tracked focus time, theme setting and the session in progress) is stored only in your browser's local extension storage, on your own device. The extension makes no network requests and uses no analytics or third-party services.

It reads the titles and addresses of your open tabs only so that you can choose which tabs to focus on. That information never leaves your browser.

You can export your data at any time from the Backup / Import page. Removing the extension deletes all of its stored data.
