If it’s information that logically belongs to a post/page – you store it in postmeta (with update_post_meta function). If it’s something that pertains to a user – usermeta table is for you. More still, there’s Settings API in case you have a plugin that needs to persist any settings.
From your question it is somewhat unclear which of these would be best for you. What’s a “submission date“? The name and contact number, I’m guessing, are for a user, and so would belong in the usermeta. Function update_user_meta is a good place to start.
