I don't collect any data in my games, but some of them make sue of third party services that may do.

Toilet Boy

For a while, Toilet Boy did have ads enabled. Unity have deprecated the API this was built with, and I haven't bothered to update it. You should check Unity's ad privacy policies for more information on what they may collect.
