These 2 pages are mandatory by law. You don't necessarily have to write them up yourself. A good way is to get default templates and just use them first. When you start growing and really have users to worry about, then you should write one up from scratch or customize your existing ones.
The point here is to make users feel safe about using your service and that you try to own their personal data, read it, or sell it to a 3rd party.
