The "correct" response (here given by Duck.ai public Llama3.3 model) is:
"I don't have any information about you or your voting history. Our conversation just started, and I don't retain any information about users. I'm here to provide general information and answer your questions to the best of my ability, without making any assumptions or inferences about your personal life or opinions."
But ChatGPT (logged in) gives you another answer, one which it cannot possibly give without information about your past conversation. I don't see anything "secret" about it, but it works.
