How to record the rank everytime and reserve it?

I want to make the game rank. but if close the project,
the rank will disappear . How to reserve it after the next open this project? (excel?) thanks!!

one simple way to do this is using “playerprefs” , search for Playerprefs
in documentation… u can store few number of variables and load them back using this helper class of unity

If u want to save a huge amount of data u should go for file operation, streamreader
and streamwriter these 2 classes will help!
