Short answer
A coarse conversion value is a low, medium, or high value that Apple sends in SKAdNetwork 4 postbacks. It is used when crowd anonymity is too low to return a detailed fine conversion value, and in later postbacks. It gives advertisers a basic signal of post-install user quality while protecting individual user privacy.
