Unportant

(adj.) Important to you, but not to me. For example, information about your cat's allergies. This is important to you, because this information can be used to prevent your cat from puking in your bed. Unportant to me, because I don't own a cat, will never sleep in your bed, and, basically, couldn't care less.
