Firebase Cloud (UUID)


I am trying to make so that each field which is represented with a fake email also has a count of variable that is not someone else count , I have managed to make a storage, and sending the user information to the firebase cloud, the email is updating, and so does the variable, but I am not sure how to make it so that the variable stays the same for the user that already had 3 counts, and didn’t log in, cause of storage I have made and the variable all of the fields get updated which I don’t want of course.

Here is the screen shot of the firebase user id next to the fake email and the ID is just the number that counts based on how many clicks you did, but also storages so that the next time the same user gets the increment when he left off.
