Is it safe to give ChatGPT your family's information? What to share and what to keep
Short answer: some of it, yes. All of it, no. And you need a lot less than you think.
The sensible rule
Treat anything you type into a chatbot like something you’ve written on a postcard. Probably fine. Not where you put the PIN.
Health experts and online safety people say roughly the same thing: don’t paste identifying details into free AI tools. Full names with dates of birth. Medical records. Addresses. School plus class plus photo. That combo is the problem, not any one piece.
What’s fine to share
The stuff that makes AI useful for running a house is surprisingly boring:
- “Two adults, two kids, one at primary school, one at preschool.”
- “Pick-up is at 3:15 Monday to Thursday.”
- “One of us does sport runs, the other does swimming.”
- “We don’t eat pork.”
- “Bins go out Tuesday night.”
That’s operational. It’s the shape of the week. Nobody can do much with it except help you get there on time.
What to keep out
- Full names with birthdates
- Medical diagnoses and medication details
- Bank details, account numbers, passwords
- Anything about a child you wouldn’t say in front of them
- Other people’s private stuff (your sister’s divorce is not household admin)
The trick: use roles, not names
You can run a whole household plan with “Kid 1”, “Kid 2”, “Parent A”. The AI doesn’t need to know your kid is called anything to remind you about their excursion.
Check your settings
Both ChatGPT and Claude have two settings you should look at: whether your chats are used to improve their models, and memory. They’re separate switches. Turn off what you don’t want. Two minutes, once.
ChatGPT: Settings → Data controls → Improve the model for everyone. Memory is under Personalization. Claude: Settings → Privacy → Help improve our AI models. Memory is under Capabilities.
Why “write it down once” is also the privacy move
Here’s the bit people miss. When you explain your family from scratch in every chat, you overshare, because you’re trying to give enough context for each new question. Bits of your life end up scattered across a hundred conversations you’ll never find again.
When the house is written down once, in one place you control, you decide exactly what’s in it. You can read it. You can delete a line. The AI reads what it needs, when it needs it, and nothing extra.
That’s how I’m building Ask The House (opens in a new tab): one written-down house that your own AI reads when you ask it something. You can see every word it knows, because you wrote them.
The short version
Share the shape of the week. Keep out identities, health and money details. Use roles instead of names. Check your settings. And keep your house in one place you own, not sprinkled through your chat history.
