TabSpace is a browser extension that helps you view and organize your tabs.
TabSpace does not share or track any information ever, the extension runs in complete isolation and stays fully offline.
The main goal of TabSpace is to display your tabs in an intuitive format. In order to do this, TabSpace does need to access some tab data from your browser (like the title and URL of each tab) which is then shown to you. As mentioned earlier, none of this data is ever sent anywhere.
TabSpace does not retain any tab data once it has been shown to you, unless you optionally request that TabSpace save a list of your tabs for later. By default, your saved tabs are stored securely within TabSpace on your machine, but you can also ask TabSpace to save them as bookmarks in your browser.
