Is ChatGPT Private? Your UK Privacy Guide

The Short Answer: Is ChatGPT Safe for Private Conversations?

ChatGPT is not private by default. OpenAI stores your conversations and, unless you change one setting, may use them to train future AI. For everyday questions, this is rarely a concern.

But never type passwords, bank details, or NHS numbers. Turn off training in Settings, then Data Controls, and use Temporary Chat for anything sensitive.

What Does OpenAI Do with Your Conversations?

When you use ChatGPT, OpenAI receives and stores the full conversation. That includes everything you type and everything ChatGPT writes back.

By default, on a free or Plus account, OpenAI may use those conversations to improve their AI models. They also retain data for at least 30 days after you delete a chat, for safety monitoring purposes.

There is a difference between ChatGPT and a search engine that is worth understanding. When you search Google, Google records what you searched for. When you use ChatGPT, OpenAI records the full conversation, including everything you wrote. That is a more detailed record.

OpenAI staff can access conversations in certain circumstances, such as safety investigations. Their privacy policy sets this out in full. I read it so you do not have to. The part that matters most for everyday users: your conversations are stored, and OpenAI may use them for training unless you opt out.

How to Stop Your Chats Being Used for AI Training

You can opt out. OpenAI gives you a setting for this. Here is how to find it.

Step 1. Log into ChatGPT at chat.openai.com.

Step 2. Click your name or profile in the bottom-left corner. On some browsers it appears as a small circle with your initial.

Step 3. Click "Settings".

Step 4. Click "Data controls".

Step 5. Find the toggle labelled "Improve the model for everyone" and switch it off.

Once off, your new conversations will not be used for training. Conversations you had before the change may already have been processed.

If you use a Team or Enterprise account through work, your data is excluded from training by default. Nothing to change.

Is ChatGPT Safe for Confidential Information?

No. Do not type confidential information into ChatGPT.

Confidential means anything you would not post publicly: passwords, bank account numbers, National Insurance numbers, NHS record details, legal correspondence, work documents with client names, photographs of identity documents. If you are unsure whether something counts, assume it does.

Conversations in ChatGPT are stored on OpenAI's servers, not just on your device. They are not end-to-end encrypted the way a messaging app like Signal is. And while OpenAI has security in place, no online service is entirely proof against data breaches or internal access.

None of this makes ChatGPT dangerous for everyday use. General questions, drafting help, public information lookups, and creative tasks carry very little risk. The key is keeping personal and confidential details out entirely. For a full list of what to keep out, see our guide on what not to tell ChatGPT.

Is ChatGPT Private? What That Actually Means

"Safe" and "private" are different things, and the difference matters here.

Safe means the service has security measures to protect your data. ChatGPT meets a reasonable standard on this front.

Private means only you can see the content. ChatGPT does not meet this standard. Your conversations are stored on OpenAI's servers, and in certain circumstances staff can access them.

Think of it less like a sealed letter and more like writing on a postcard. It gets where it needs to go, and it is generally protected. But it is not sealed from everyone at the company.

ChatGPT is not end-to-end encrypted the way WhatsApp or Signal messages are. End-to-end encryption means only you and the other party can read the content, not even the company running the service. ChatGPT does not work that way.

For most everyday conversations, this barely matters. Asking for recipe ideas, help writing a card, or a film recommendation carries very little risk. The concern arises when people type personal details, medical records, confidential work files, or anything with names and addresses. Those things should stay out. Our complete ChatGPT safety guide covers the broader picture.

Your UK Rights Under GDPR

If you live in the UK, you have rights under the UK GDPR (General Data Protection Regulation) that apply to how OpenAI handles your data.

Your main rights include:

• The right to access. You can ask OpenAI for a copy of the data they hold on you.
• The right to deletion. You can ask them to delete your personal data, subject to certain legal retention requirements.
• The right to object. You can object to your data being used for AI training. The opt-out toggle in Settings is the quickest way to act on this.

To make a formal data request, contact OpenAI via their Privacy Portal or email dsar@openai.com. The ICO (Information Commissioner's Office) has published specific guidance on ChatGPT and your rights when using AI services in the UK.

If you want to request a copy of your data or have it deleted, the ICO's guide to getting copies of your information explains how the process works.

What IS Safe to Type into ChatGPT?

Much coverage of ChatGPT privacy focuses on what to avoid. That is useful, but it misses something: most things people want to ask are completely fine.

You can safely type:

• General questions about history, science, how things work, or current affairs
• Recipe ideas and cooking questions
• Help drafting a letter or email (without real names, addresses, or sensitive context)
• Film, book, TV, or podcast recommendations
• Grammar checking or writing feedback on draft text
• Ideas for a day out or holiday (general suggestions, not your home address)
• Creative writing or story ideas
• General medical topics, as distinct from your specific records or symptoms

I use ChatGPT daily for drafting and research. I keep medical questions, anything with names and addresses, and work documents with client information entirely off it. The line I draw: if I would be comfortable with a support technician at a large company potentially seeing it, it goes in. If not, it does not.

How to Use Temporary Chat for Sensitive Topics

Temporary Chat is a feature that lets you have a conversation with ChatGPT that is not saved to your history and, according to OpenAI, will not be used to train their AI.

We checked: when you use Temporary Chat, the conversation does not appear in your sidebar history after the session ends.

To start one, look for the pencil or "new chat" icon at the top of the page. You will usually see a "Temporary chat" option there. The exact location shifts with updates, but the feature has been available since early 2024.

Keep in mind that OpenAI may retain brief logs even from temporary sessions for safety monitoring. But those conversations will not sit in your account history or be used for model training.
