Is Web Scraping for Academic Purposes Illegal? (Regarding a Website with Free Trials)

Hi all, I'm currently working on an academic research project and came across a website that sells data. However, they offer free trials during which I can access the data I need for my research. I was wondering if web scraping this website during the free trial period for academic purposes is considered legal? I know this can be a very gray territory. Any insights or advice would be greatly appreciated. Thanks in advance!
