Do you know what you need to cover?
Here is a quick run down to get you started.
Notice – if you are collecting data even if it is just email addresses then you need to advice what you intend to do with that data.
Choice – you must respect the choices of your users, make sure you are ready to cope with Unsubscribe requests or data storage requests with some FAQs.
Access – users must be able to gain access to you and get a response. If you use a Gmail address and that goes into a SPAM box that you never check, then users could get cranky and things could get ugly, be prepared and accessible.
In the US, privacy legislation may vary from one state to another. Look into it carefully and protect yourself appropriately.
