ChatGPT incognito mode is the nickname people use for Temporary Chat, and OpenAI’s current help docs make the tradeoffs pretty clear: it won’t use or create memories for personalization, it won’t appear in your history, and it won’t be used to train models. It is still not a magic invisibility cloak, though. OpenAI says it may keep a copy for up to 30 days for safety purposes, and if you use GPTs with actions, data sent to third parties follows the recipient’s privacy policy.
This update focuses on what Temporary Chat actually does in 2026, how it differs from memory and chat history, and when archiving or deleting a conversation is the better move. For OpenAI’s own wording, start with the Temporary Chat FAQ, the Memory FAQ, and the archive/delete guide.
What ChatGPT Incognito Mode Means Now
OpenAI does not market a literal “incognito mode” label in the product. The current feature name is Temporary Chat. That is the version to look for in the app, and it is the closest ChatGPT has to a private window for one-off prompts, sensitive questions, and sessions you do not want mixed into your normal history or personalization.
Temporary Chat is most useful when you want a clean session without long-term context. It is a good fit for prompt testing, quick research, private brainstorming, and any chat where you do not want future conversations influenced by what you said this time.
What Temporary Chat Actually Does
- It does not access or create memories for personalization.
- It does not appear in your chat history.
- It does not get used to train OpenAI’s models.
- It still follows your custom instructions if they are enabled.
- OpenAI says it may still keep a copy for up to 30 days for safety and security purposes.
That last part matters. Temporary Chat is designed to limit retention and personalization, not to promise that nothing is ever stored under any circumstance. OpenAI also notes that Temporary Chat may still use information from prior conversations for limited safety and security purposes.
Memory, History, And Training Are Three Different Things
This is where a lot of ChatGPT privacy advice gets sloppy, so it is worth being precise. OpenAI’s current Memory FAQ separates personalization into saved memories and reference chat history.
- Saved memories are the specific things you have asked ChatGPT to remember.
- Reference chat history lets ChatGPT use useful details from past chats to personalize future replies.
- Temporary Chat bypasses both for that session.
OpenAI says that if Reference chat history is on, ChatGPT can keep information from past chats unless you delete or archive those chats. If you turn off Reference chat history, the information ChatGPT remembered from past chats is deleted from OpenAI’s systems within 30 days. If you want something fully removed from personalization, you may need to delete both the saved memory and the underlying chat that introduced it.
OpenAI also says turning off Memory or Personalization does not disable safety features that may use limited, safety-relevant context in rare, high-risk situations.
Temporary Chat Vs Archive Vs Delete
- Temporary Chat: use it for a session you do not want saved in history or used for personalization or training.
- Archive: hide a chat from the sidebar while keeping it in your account.
- Delete: remove a chat from view and schedule it for permanent deletion within 30 days.
If your real goal is just to clean up the sidebar, archiving is usually the lighter move. If you want a full walkthrough on that side of things, read how to archive chats in ChatGPT. OpenAI’s archive/delete guide also notes that archived chats stay in your account under the normal retention rules, while deleted chats are removed from your history and scheduled for permanent deletion within 30 days.
One more nuance: if a chat used connected apps or synced data, deleting the chat removes the retained conversation data from your account, but simply disconnecting the app does not remove past conversations that already used that data.
How To Start A Temporary Chat
- Open ChatGPT and start a new chat.
- Look for the Temporary button in the top-right corner.
- Turn it on before you start typing anything you want kept out of history.
- Use the chat normally, knowing it will not create or use memories for that session.
- When you are done, close it and move on without needing to manually archive it.
If you are on a GPT and the GPT has actions, be extra careful about what you share. OpenAI says data sent to third parties through those actions is governed by the recipient’s privacy policy, and the recipient may keep that data for longer than 30 days or use it for other purposes.
When I Would Use Temporary Chat
- Testing prompts and comparing outputs.
- Asking a sensitive question you do not want folded into future personalization.
- Doing quick research that should not shape later chats.
- Using ChatGPT on a shared or work device and wanting a cleaner session boundary.
- Trying a GPT workflow before deciding whether it fits your normal setup.
My rule of thumb is simple: use Temporary Chat when the conversation should stay isolated, archive when you just want less clutter, and delete when you want the conversation scheduled for removal. That is the cleanest way to think about ChatGPT privacy without pretending the product works like a browser tab in incognito.
