Definitely no license given. Additionally I usually throw an "all rights reserved" on there somewhere to acknowledge my authorship and ownership of the product. That's great for code + the specific execution of it... for me I often have to also do design engineering and content/concept prototyping as part of these projects. Creative work in addition to the code. I'm not sure there's a way to protect those ideas the same way you can the code.
