When do you tell someone you don't want children — in the profile, in the messages, or across the table? For most dating contexts this is a genuinely hard timing problem, and members have strong, earned opinions about it.
The case for early — profile-level, unmistakable, before the first hello — is arithmetic. The most expensive outcome in dating is not rejection; it is three months with someone who read "childfree" as "flexible." Members who front-load the disclosure report fewer matches and dramatically better ones. The word choice matters too: "don't want kids" in a profile is routinely interpreted by hopeful readers as "doesn't want kids *yet*," which is why many members use harder phrasing — "childfree for life," "no kids, not ever, this is not a phase" — precisely because it is unromantic. The people it filters out are the point.
The case for date-one disclosure rather than profile disclosure is narrower but real: some members, particularly women, report that explicit childfree profiles attract a specific genre of unpleasant attention, and prefer to state it plainly in the first conversation instead. The consensus boundary is that it must be settled before anyone develops feelings — which in practice means before or during the first date, never after the third.
What members say does not work: hinting ("I love my freedom"), assuming a shared understanding from a checkbox, or waiting for the other person to raise it. The other person is often waiting too, and two people politely not asking is how month three surprises happen.
The follow-up question — "are you *sure*?" — deserves its own preparation, because you will get it. Members' most-reported effective answer is calm brevity: "Yes. It's one of the few things I've always been sure of." Delivered without defensiveness, it ends the topic; delivered with irritation, it becomes the topic.
Obviously, this entire timing problem is the thing this app removes — here, the disclosure is the front door. But most childfree people spent years dating where it wasn't, and the accounts below record what actually worked and what it cost when it went wrong.
