I am planning on using Google Tag Manager to implement all my tracking data, but I am also stating to think through the possibilities of leveraging that data within my app. The analytics engines I see plugins for are Google, MixPanel, Segment, Heap, HotJar, and Woopra. I assume that all of these are also available via API.
Is anyone pulling analytics data into their app and then storing it locally and running additional workflows on it i.e. additional calculations and creating new things?
