New to Software Development/ Self taught. Please bear with me if i did not provide enough Information

I don't know much about software security, but i do know that you can Reverse engineer everything your program does, so how would you folks go about securing such sensitive Data?

This program won't be intended to be distributed to other people than this one person, but i do want to learn about this topic incase other ones are interested in using it.
