GPT o1 to Save Data on Past Conversations

So I really like for GPT 4o that any information that I told it, it automatically saved this information, and it could draw upon that knowledge when we talked, even if it was several months later for an unrelated conversation. I know that the new GPT o1 no longer saves data for privacy concerns.

Do we know if the Devs will provide us the option for ChatGPT to save our data if we opt in? I figure it should be more beneficial to their business model anyway, because long term it’ll allow them to target ads better (which I also love targetted ads so another plus).
