Duke is a free Chrome extension developed by AptApps that allows users to clear all browsing data with just one click. It falls under the category of Browsers and the subcategory of Add-ons & Tools.

With Duke, users can easily clear various types of data including websites' app caches, the browser's cache, cache storage, cookies, download list, file systems, history, IndexedDB data, local storage data, plugins' data, service workers, and WebSQL data.

One of the key features of Duke is its zero configuration. Users can simply install the extension and start using it without any additional setup or customization. Additionally, Duke only requires one permission, "chrome.browsingData," which can only be used to remove browsing data as stated in the official developer documentation.

Please note that passwords and form data are not removed by Duke, as their storage is optional.
