How do I delete my ChatGPT history?

There are three levels: delete one chat, wipe everything, and stop your content from being used for model training. All three take a few clicks on the web version; the mobile app menus are laid out the same way.

Delete a single chat

1. On chatgpt.com, find the conversation in the left sidebar.
2. Hover over its title and click the … icon that appears.
3. Choose Delete and confirm. The chat disappears from the list immediately.

Wipe everything (Delete all chats)

1. Click your avatar in the top-right corner → Settings.
2. On the General tab, find Delete all chats.
3. Click and confirm; every conversation on the account is removed.

⚠️ Shared-account users: this wipes the entire account, including everyone else's chats. On a shared account, only delete individually — Delete all chats is for dedicated accounts only.

Turn off the training toggle (optional)

If you'd rather your conversations not be used to improve the models:

1. Avatar → Settings → Data controls.
2. Switch Improve the model for everyone off.

Good to know

• Deleted chats no longer display anywhere, though OpenAI may retain data briefly per its policy before purging. That retention is invisible to other users — once deleted, they can't see it.
• If you want no trace from the start, Temporary Chat is the cleaner approach: see "How do I use Temporary Chat (incognito mode) in ChatGPT?"
