Can you provide details on the 25 free responses?

Hello,

i know your free account includes 25 free responses per month. Can you explain what a “response” is? Is that when a person answers a single question, or is that the response you collect as part of lead generation? For example I am not interested in generating leads, I just want to create trivia quizzes for fun, would an answer for those quizzes still count as part of the 25?

And if I had say 5 quizzes each with 5 questions, and if someone does all 5 quizzes (and thus all 25 questions) in one day, does that exhaust the 25 limit?

What happens when the limit is reached, will the quiz become un-playable?

Thank you.
