The Webtrends Advanced Analytics (WAA) app for SharePoint 2013 and Office 365 is hosted locally in your organization’s app catalog. If you don’t have a local app catalog, you may be prompted to create one during the initial app deployment (this may require some SharePoint configuration if your SharePoint implementation is not currently configured to allow for the use of apps).
No matter which version you chose to go with, Office 365 or SharePoint 2013 installed to your own servers, the Webtrends Advanced Analytics app uses a custom action to deploy .js to your site collections. You must have sufficient SharePoint access rights to upload the app to your app catalog, deploy it to site collections, and modify any site collections the app is deployed to. This typically requires at least Site Collection Administrator level rights.
