AI Chatbot Privacy: Settings to Change in 2026
Your chatbot conversations may train the next model by default. Here are the exact settings to change in ChatGPT, Gemini, and Claude to keep your data yours.
Every time you paste a work document or a personal detail into a chatbot, you may be donating it to train a future model. On the free and even the paid consumer tiers, that data collection is on by default. Turning it off takes about two minutes per service.
Quick answer
To protect your privacy in AI chatbots, turn off model training in each service's data controls, disable the memory feature so the bot stops saving details about you, use temporary or incognito chats for sensitive questions, enable two-factor authentication on the account, and never paste passwords, medical records, or other people's private information. On ChatGPT this lives under Settings then Data Controls.
Key takeaways
- Consumer chatbots use your chats to train models by default; you must opt out.
- The memory feature is on by default and quietly builds a profile of you across chats.
- Temporary chats are the safest way to ask sensitive questions.
- Paid consumer tiers are not automatically private; only Enterprise and Business tiers exclude training by default.
- The strongest control is behavioral: do not paste secrets into a chatbot at all.
Turn off model training
This is the setting that matters most. By default, your prompts and the assistant's replies can be reviewed and used to improve the model, which means your text may pass through human reviewers and end up baked into a future version.
- ChatGPT: open your profile, go to Settings, then Data Controls, and toggle off "Improve the model for everyone." This applies across all your devices.
- Google Gemini: open Activity settings and turn off Gemini Apps Activity, which also stops human review of your conversations.
- Claude: consumer chats are not used to train models by default, but review your data settings to confirm and to manage retention.
Opting out does not always delete past data, so do it early. Enterprise and Business tiers exclude your data from training by default, but the standard consumer plans, including paid ones, generally do not.
Disable memory and use temporary chats
Two features quietly expand how much a chatbot knows about you.
Memory lets the assistant remember details across separate conversations, such as your job, your projects, and preferences you mentioned once. It is convenient and also a growing dossier. In ChatGPT, go to Settings, then Personalization, then Memory, and disable "Reference saved memories." Clear the existing memories while you are there.
Temporary chats are the privacy escape hatch. A temporary chat is not used for training, does not update memory, and is deleted after a short retention window kept only for abuse monitoring. Use it for anything sensitive: health questions, legal worries, financial figures, or work material you are not sure you can share.
Here is when to reach for each mode:
| Situation | Recommended mode |
|---|---|
| Casual, non-sensitive questions | Normal chat, training off |
| Health, legal, or financial questions | Temporary chat |
| Anything involving work data | Temporary chat, or the company's approved tool |
| Brainstorming you want remembered | Normal chat with memory on |
Secure the account itself
Your chat history is only as safe as the login guarding it. A hijacked chatbot account can expose months of conversations that may include things you would never post publicly.
- Turn on two-factor authentication. In ChatGPT this is under Settings, then Security. Prefer an authenticator app or a security key over SMS.
- Use a long, unique password stored in a manager; see our guide to choosing a secure password manager.
- Review active sessions and connected apps periodically and revoke anything unfamiliar, the same way you would audit third-party app access.
What never to paste
No setting protects data you volunteer. Treat a chatbot like a public forum, because in the worst case that is where your text could end up.
Do not paste:
- Passwords, API keys, or recovery codes.
- Full medical records or other people's health details.
- Government ID numbers, banking details, or card numbers.
- Confidential work material such as unreleased plans or source code you do not own the rights to share.
If you need help with sensitive content, rewrite the prompt using generic or fictional placeholders. The model can still help with the structure of a problem without the real names and numbers.
What to do right now
Two minutes per service closes the biggest gaps:
- In each chatbot, open data controls and turn off model training.
- Disable the memory feature and clear existing saved memories.
- Switch to temporary chat before asking anything sensitive.
- Enable two-factor authentication and set a strong unique password.
- Adopt a personal rule: no passwords, IDs, health records, or confidential work data in any chatbot.
Frequently asked questions
Does paying for ChatGPT Plus make my chats private?
No. The consumer Plus tier has the same default privacy settings as the free tier, and your data can be used for training unless you opt out. Only Enterprise and Business tiers exclude your data from training by default.
Can I delete my chat history?
Yes, you can delete individual chats or your whole history in the account settings, and you can request account deletion. Note that deleting a chat does not necessarily remove data already used in training, which is why opting out early matters.
Are temporary chats really not used for training?
Correct. Temporary chats are excluded from training and do not update the memory feature. Providers retain them briefly, typically up to 30 days, only for safety and abuse monitoring, then delete them.
Is it safe to use a chatbot for work documents?
Only through your employer's approved and configured tool. On a personal consumer account, assume anything you paste could be reviewed or used for training. Use a temporary chat with placeholders if you must, and never upload confidential files.
