Hi Xenos Digital Store,
Thank you for bringing this concern here. yes, That is true the app installation is completely free for trying breadcrumb rich snippets and Article rich snippets. If you want to have full access to the features you need to upgrade your free app to premium.
But, Not to worry with premium upgrade we offer 30 days money back guarantee if the results are not satisfactory,
