Basic integration of Unity Analytics which collects anonymous usage statistics. This data is used to know the number of daily active users, how many people reached a certain high score, which game mode is preferred and other similar information. This data is anonymous and is only used to help improve games. The same tools are also used to get performance reports so we can track and resolve game crashes and errors. I do not own the game idea. It is from the popular browser Chromium, which is open-source in nature. No personal information is collected.
