Games sends one request for analytics in every game 10 seconds after the game started (allowing you to get the analytics from the game dashboard). It contains a unique player ID, the game’s ID, the platform the game runs on (android, windows…), the URL to the game, and the game version. The unique player id is not used to track the player, only to be able to know the number of unique players. All the data is aggregated, meaning it is not linked to the unique IDs, we can see for example how many users are on Android but not what users exactly nor what other attributes those users have. The data is only available to the creator of the game and the GDevelop company, it is not shared with anyone else.

But it only talks about GDevelop itself (the IDE), not GDevelop games.
