TL;DR
- ChatGPT is worth using every day. Drawing a clear line about what goes in it is what lets you keep using it without second-guessing yourself later.
- OpenAI confirms your chats are stored until you delete them, and used to train its models unless you turn that setting off.
- There are two different places your information lands: a chat, and Memory. A chat is temporary context. Memory is permanent. Most of this list is about Memory.
- On the free plan, the topics you talk about help decide which ads you see.
- Two settings take about four minutes and change what happens to everything you type from here on.
Here’s where the line is
You can run most of your life through ChatGPT. The meal plan, the email you were dreading, the birthday party you are somehow hosting in nine days.
Because you’re going to use it that much, it’s worth deciding once, on a calm day, what you will and won’t type into it. Not because ChatGPT is dangerous. Because when you’re tired at 10:47pm you type faster and think less, and a rule you already made is easier to follow than a decision you have to make in the moment.
If you’ve ever asked ChatGPT to help you word a note to your kid’s teacher, keep reading.
I’m Alyssa Rowe, the mom behind Simplify Life, and I use ChatGPT every single day. I also have a short list of things that never go in. Here it is, along with what OpenAI actually says happens to what you type, straight from their own documentation.
Does ChatGPT save what you type?
Yes. Your conversations stay in your account until you delete them, and unless you turn one setting off, OpenAI may use them to train its models. That comes from OpenAI’s own explanation of how your data is used.
A few more things they confirm:
- Deleting a chat removes it from your history immediately and schedules it for permanent deletion within 30 days. There are two exceptions: if it was already de-identified and disconnected from your account, or if OpenAI has to keep it for legal or security reasons (delete and archive policy).
- Along with your prompts, they collect your IP address, browser and device details, and the general area you’re in (privacy policy).
- Your information can be disclosed to vendors and service providers, to OpenAI’s affiliates, and to government authorities when the law requires it.
- Even with training turned off, giving a thumbs up or thumbs down means that entire conversation may be used for training anyway.
So this is not a question of whether ChatGPT is trustworthy. It’s a question of what you want stored on a company’s servers, where you can’t see it and can’t take it back once it’s been used.
A chat and Memory are two different things
This is the part that changes everything, and almost nobody explains it.
A chat is one conversation. What you type there is context for right now: the sick kid, this week’s schedule, the specific problem you’re solving today. When you’re done, you can delete it.
Memory is the permanent file ChatGPT keeps about you. It carries into every new conversation without you re-explaining. Your kids’ ages, the dairy allergy, the fact that weeknights are low-energy.
The line is this: Memory is for what’s always true. A chat is for what’s true today.
That’s why “don’t tell ChatGPT about your health” is bad advice. Asking it a health question in a chat is a completely reasonable thing to do. Saving your medical history to Memory, so it’s attached to you permanently and shaping every answer, is a different decision entirely.
So when you read the list below, the question isn’t “am I allowed to type this?” It’s “does this belong in the permanent file?”
10 things to leave out by default
- Passwords, passcodes, and two-factor codes. Nothing you’d type into a login screen. There’s no version of this that’s useful enough to be worth it.
- Card, bank, and routing numbers. To be clear, using ChatGPT for money is completely fine. Ask it to build you a budget, talk through a spending plan, help you figure out where the grocery money keeps going. It just never needs the actual account number to do any of that.
- Social Security, passport, or driver’s license numbers. Yours, your significant other’s, or your kids’.
- Full birthdates. A birthday month is plenty for planning. The full date is an identity-verification answer at half the places you have accounts.
- Exact addresses. “We live about twenty minutes from the school” does the same job for planning purposes.
- Your kid’s school name paired with details about your kid. Either one on its own is unremarkable. Together they identify a specific child in a specific building. I say “my second grader” and everything still works.
- Private legal or medical documents. This means uploading the actual document. Asking a question about a diagnosis or a custody situation in a chat is different, and it’s genuinely useful. It’s the file itself that stays out.
- Travel dates and when your house will be empty. Flight times, the week you’re at the beach, the nights nobody’s home.
- Documents pasted in from a public share link. If the link works for anyone who has it, the document is already open to anyone who has it.
- Anything only true this week. The sick kid, the chaotic schedule, the empty fridge. Not because it’s sensitive, but because Memory is for the always-true. If you wouldn’t want ChatGPT bringing it up in March, don’t save it in September.
The honest caveat on all ten: any of these can be worth it if you’ve actually thought through the tradeoff and decided the help is worth it. What you want to avoid is handing something over without noticing you did.
And if you scan that list and realize you’ve done four of them, same. Nothing about that is a crisis. It’s just a reason to change two settings.
Is ChatGPT safe to use?
Yes, for the overwhelming majority of what you’re already using it for. Meal plans, wording a hard email, untangling your week, starting the project you don’t have the bandwidth to start.
My own setup is not locked down to nothing. My Gmail, Drive, and Calendar are all connected to ChatGPT, because the reason it saves me real time is that it can see my actual life. I made that trade on purpose, knowing what it costs. Which brings me to the part of that trade most people don’t know about.
What connected apps keep after you disconnect them
When you connect Gmail, Drive, or Calendar, the information those apps pull in can stay stored inside the conversations that used it.
Here’s the part worth writing down: disconnecting the app later does not delete those older chats. Disconnecting only stops ChatGPT from pulling anything new. Everything it already pulled is still sitting in the conversations where it landed.
According to OpenAI’s policy, the only way to remove that information is to delete the conversations themselves.
So if you connected Drive one afternoon and had ChatGPT read something you’d rather it hadn’t, unhooking Drive does not undo it. Deleting that specific chat does.
On the free plan, your chats help choose your ads
If you’re on free ChatGPT, you see ads. And per OpenAI’s own explanation, those ads are chosen by matching advertisers against the topic of your current conversation, your past chats, and your past interactions with ads.
Two things worth knowing, because the scary version of this isn’t the true version. Advertisers do not see your chats, your history, or your memories. They only get aggregated numbers like total views and clicks. And you can turn ads personalization off, which limits ad selection to just the conversation you’re in right now.
This isn’t a reason to stop using free ChatGPT. It is a reason to know that what you talk about is doing something besides answering you.
Two settings, about four minutes
Time needed: 4 minutes
Turn off model training and start using Temporary Chats, the two changes that do the most for the least effort.
- Turn off “Improve the model for everyone.”
Open ChatGPT, tap your profile icon, go to Settings, then Data Controls, then switch off “Improve the model for everyone.” Mine has been off since the day I found it, because I am a bit of a control freak about my own information. Your chats still show up in your history exactly like normal. They just stop being used as training material.
- Know that it applies everywhere.
The setting covers your whole account, so once it’s off on your phone it’s off on your laptop too. There’s no second toggle to find.
- Use Temporary Chat for quick questions.
A Temporary Chat is deleted from OpenAI’s systems within 30 days, is never used for training, doesn’t save to your history, and doesn’t create memories. I use these constantly for one-off questions I don’t want stored to Memory or cluttering up my chat list.
- Open Manage Memory and read what’s in there.
Settings, then Personalization, then Manage. You can delete anything individually. Most people have never looked, and it takes two minutes.
You can switch the training setting back on anytime, as many times as you want. OpenAI states there are no restrictions on changing it.
How to get the same help without handing over the details
None of this matters if it makes ChatGPT worse at helping you. It doesn’t, and here’s the swap.
Replace the identifying detail with the role. “My second grader” instead of a name. “A friend going through something hard” instead of hers. “A bill for around four hundred dollars” instead of the account it came from. Describe what’s happening and leave out who it identifies.
The answers come back just as good. ChatGPT does not need to know who anyone is in order to help you handle the situation. It needs to know what the situation is.
FAQ
Yes, unless you turn it off. OpenAI states that content from its services for individuals, including ChatGPT, may be used to train its models, and that you can opt out in Settings under Data Controls. Once you opt out, new conversations are not used for training.
It leaves your history immediately and is scheduled for permanent deletion from OpenAI’s systems within 30 days. Two exceptions apply: if the chat was already de-identified and disconnected from your account, or if OpenAI must keep it for security or legal obligations. Deleted chats cannot be recovered.
Not under 13. OpenAI’s privacy policy states its services are not directed to or intended for children under 13, and that users under 18 need permission from a parent or guardian.
Where to start
You don’t need a privacy overhaul. You need one setting turned off, two minutes inside Manage Memory, and the habit of saying “my second grader” instead of a name.
And if part of you is thinking you’d use ChatGPT for more than you currently do if you just knew where to start, that’s the part I can help with. I put together three ways moms are handing the mental load over to AI, with the exact words to type. It’s free, it works on the free version of ChatGPT, and you can try the first one tonight.
