When deploying the "LiveTiles Intranet Hub"-app a set of permission requests are created that need to approved in the "API Management"-section in the SharePoint Admin Center.
Please be aware the you might not need all permissions, if you don't need the functionality that requires them. Please also be aware that everything is executed under the current user. That means users will only be able to load data, they are actually allowed to load. Also all calls to Graph are performed directly from the user's browser. We do not store anything in our database, except the hub's configuration.
To give you a better understanding of which permissions we require and why we require them, please view following list. Additionally you can consult the official documentation from Graph.
