How do I change my email?

You see this is a school Email and it logs me off when I graduate and I like this program. The problem with me emailing to change my account is that I can't email outside of peers, faculty, and teachers and CollegeVine can't email me. So a feature that would be helpful for people like me is if you could just change your email form inside the app or if you could save progress from one account to another. Why isn't there one already too? Is it a coding problem or for security purposes? Just wondering and if there is another way please let me know.

Sorry this isn't much about animations I am just was wondering.
