Flight Review - Cesium visualisation license


I was looking into the Cesium flight log visualisation and I was wondering what the licence situation with respect to that. I know Cesiumjs is released under the Apache 2.0 license and Cesium Ion is from what I understand the hosting and data. When I run the 3d visualisation does it use Cesium Ion, should I be concerned about licencing?


Yes you’ll need an API key. Here’s their pricing: https://cesium.com/pricing/.
Flight Review currently still uses the Community plan, getting to the limit though.
