You need to buy a license to remove the “Powered by ZingChart” watermark and “About ZingChart” context menu item from your charts. (Any user can remove or hide the ZingChart loading screen. See the ZingChart Branding Tutorial for instructions.)
We offer multiple licensing options to meet the varied needs of our users, including website, internal, SaaS, Enterprise, OEM, and Universal licenses. Contact our sales team at email@example.com or start a chat (bottom-right corner of the page) to learn more.
