How could to transfer data game to game at any point?

I've tried finding a good source that could teach me how to transfer data game to game but I couldn't find any. Either it's all been deleted such as the Universes event. There was also the TeleportService which sends arguments to the other server but this is only when the player is teleporting to the other server. Is there anyway to possibly do this?
