I found out the hard way that Hulu ends your subscription immediately.
Edit: I was remembering a free trial, not paid subscription.
Is that even legal in the States? Or do you at least get a partial refund for the remainder of the month?
That’s not even true, it shows clearly on their website that is not the case

This was a couple years ago and it was a trial of the Hulu no ads plan. According to This help page they don’t even offer trials of the no ads plan anymore. The page you referenced also states that the Hulu + live TV trial ends immediately upon cancelation.
