auto save?

i have a really good question, is it possible to have an auto save checkpoint? such as i have a charecter tht just beat lvl one in a game, is it possible to:
add event--> event activation--> then what script would i do to make this happen, and if so how can i make so when i move it to my phone it will save to the phone in someway?
