Is there a way to save data from a plugin without a published place? [closed]

I am working on another plugin. This time is has a bunch of games for the user to calm down with or refresh with. I have one of the games ready, but there is only one thing missing: Saving user data. I know how to use the DataStoreService and how to save data to it, but the point of the plugin is for users to relax from creating a game. The game probably isn't published, so they probably can't save data. I have an int to save for the game, and I do not know where to save it to.

If there is another way to save data without using the DataStoreService, then please answer my question.

Thanks!
