Does deleting ChatGPT history delete it? (October 2026)

What happens when you delete a chat

A deleted chat is gone from your view immediately and erased from OpenAI’s systems within 30 days. That’s OpenAI’s own wording on its help pages for deleting chats and for chat retention, checked in October 2026.

There are three exceptions in the same sentence, and they matter:

the chat was already de-identified and disconnected from your account;
OpenAI has to keep it longer for security reasons;
OpenAI has a legal obligation to keep it.

You can’t get a deleted chat back. OpenAI Support can’t restore it either. If you think you might want it later, request a data export from ChatGPT’s settings first.

To clear everything at once, go to Settings > Data controls > Delete all chats. It also removes chats inside projects, and it can’t be undone.

Connected apps are a separate case. If a chat pulled in data from something like Gmail, deleting the chat removes the copy held in that conversation. It doesn’t delete the original email. Disconnecting the app stops future access but leaves past chats that already used its data, so delete those chats too.

Deleted, archived, memory, files and links

Each of these is stored separately, so each needs its own delete. This table is the short version, built from OpenAI’s help pages as of October 2026.

What you clear	Is it deleted?	What’s left behind
Delete a chat	Yes, within 30 days	Saved memories made from it, Library files, copies other people saved from a shared link
Archive a chat	No	The whole chat. It stays searchable and keeps normal retention
Delete a saved memory	Yes	Logs kept up to 30 days for safety and debugging; mentions in old chats
Turn off “Reference chat history”	What it learned is deleted within 30 days	Your actual chats stay in history
Delete a shared link	The link stops working	The original chat, and any copy a recipient already saved

Archiving is the trap. OpenAI says plainly that archiving “does not delete” a chat. It only moves it out of the sidebar. You’ll find archived chats under Settings > Data controls > Archived chats, where you can delete them properly.

Memory is the other one. OpenAI’s memory page says deleting the original chat “does not automatically delete a separate saved memory.” To remove something ChatGPT remembers, delete the saved memory and the chat where you first mentioned it. If you’re not sure what it remembers, our guide to whether ChatGPT can see your other chats walks through both memory settings.

Files work the same way. Deleting a chat doesn’t delete copies saved in your Library, so remove those too.

Was my data used for training?

Deleting a chat doesn’t stop it from having been used for training already. The setting that controls training is separate, and it’s called “Improve the model for everyone.”

On personal accounts, OpenAI may use your conversations to train its models unless you turn that off, as of October 2026. Turning it off only covers new conversations. OpenAI’s help page says “we won’t use your new conversations to improve our models” after you opt out. It doesn’t promise to pull older chats out of past training.

One more catch. If you tap thumbs up or thumbs down on a reply, OpenAI says the entire conversation may be used for training, even if you opted out.

Business, Enterprise and Edu workspaces are different. OpenAI doesn’t train on their content by default, but your employer’s retention rules apply, and compliance tools may still reach workspace data.

The court order and what it means now

The court order that kept deleted chats in 2025 no longer covers new chats, according to OpenAI. Here is what the sources say, and nothing more.

On May 13, 2025, a federal magistrate judge in New York directed OpenAI to preserve output log data that would otherwise have been deleted, as part of the copyright case brought by The New York Times and other news outlets. The court’s December 2, 2025 opinion describes that order.

OpenAI’s update dated October 22, 2025 says its obligations under that order ended on September 26, 2025. It says it has returned to deleting chats within 30 days. It also says it still stores “limited historical April–September 2025 user data” under a legal hold, accessible only to a small legal and security team. It also says it’s no longer required to keep conversations that originate in the EEA, Switzerland or the UK.

Separately, the same December 2, 2025 opinion denied OpenAI’s request to reconsider a November 7, 2025 order to produce 20 million retained, de-identified consumer ChatGPT logs for sampling. If you deleted chats between April and September 2025, OpenAI’s statement is the best guide to their status. We can’t tell you more than it does.

The case itself is still running. In August 2026, OpenAI filed its opposition to the news outlets’ motion for sanctions, which covers how OpenAI preserved chat logs among other issues. As of October 20, 2026, OpenAI’s statement still shows October 22, 2025 as its latest update.

How to keep a chat from being saved at all

Temporary Chat is the closest thing to “don’t save this.” You start one by opening a new chat and selecting Temporary, as of October 2026.

While a chat stays temporary, OpenAI says it:

doesn’t appear in your history;
doesn’t create or update memories;
isn’t used to train models.

OpenAI may still keep a copy for up to 30 days for safety purposes. If you save a temporary chat, it turns into a regular one and follows your normal settings. You also pick “Personalized” or “Unpersonalized” before the first message. Personalized lets it read your existing memories, so choose Unpersonalized for anything sensitive.

Temporary Chat doesn’t make you anonymous. You’re still signed in to your account while you use it.

Shared links outlive the chat in other people’s hands

A shared link is public to anyone who has it, and deleting it doesn’t recall copies. OpenAI’s sharing page, checked in October 2026, says links don’t expire on their own and can’t be limited to specific people.

To find and remove them, go to Settings > Data controls > Shared links > Manage. Delete one link at a time, or use More actions > Delete all shared links.

If someone continued your shared chat, they now have their own private copy. Deleting your link or your chat doesn’t remove theirs. Deleting the original conversation does kill its link, though. If you can’t remember what you’ve shared, the Shared links list is worth a look before you assume a chat is private.

What to do next

Go to Settings > Data controls > Archived chats and delete anything you archived but meant to remove.
Open Settings > Personalization > Memory and delete saved memories you don’t want kept. Then delete the chat where you shared that detail.
Check Settings > Data controls > Shared links and delete links you no longer need.
Turn off “Improve the model for everyone” in Data controls if you don’t want new chats used for training, and use Temporary Chat (Unpersonalized) for sensitive questions.
