Your information should be your information and used only with your permission. Since I create simple puzzle games, however, there are few ways to monetize these games except through advertising. That means many of my games incorporate APIs from the likes of Google to serve advertisements during gameplay. These APIs also include tracking and analytics data that are sent to these advertisers.
Some of my games send scores to my servers (hosted at Digital Ocean to create leaderboards to share with you and other players. I anonymize all data and do not store personally identifiable information, such as your IP address.
