"Hutch will also assign you a User-ID which is a random string of characters used to identify you as a unique player going forward... If you sign into one of the Games through Facebook, Google or Apple, in addition to the Analytics Data above, Hutch will also collect such information as Facebook, Google or Apple may allow Hutch to access, namely your full name, and if you sign in using Facebook, your Facebook ID."
Hutch creates persistent user profiles via assigned User IDs and links them with social network identities (Facebook ID, Google, Apple), enabling cross-service tracking and identification.
