I was hired as a freelancer to do some work for a company. I made a design that I love which included some of the company's data within it. I asked to put it on my portfolio and they got very defensive and angry about their data right off the bat and we no longer work together. I updated the design to not include ANY of their data or anything referring to them as I love the design and I want to showcase it on my portfolio site that I am working on.
I would really like for them not to use my design for any future items, but I'm not sure if I am legally allowed to.
This is the text in my contract:
