Re-creating Battle Replay features

Hello, is it possible to recreate specific features from the battle replay or is that not publicly available? I am working on a stats tracking application and was wondering if it was possible to track data such as how many times you placed a specific card during a match, or how many total cards you placed during a match. I’ve scoured the official CR API but it doesn’t look like it has anything. Is this just simply not public information? If it is, how could I access this information?
