Quick Answer
- To clear everything, go to Settings, then Data controls, then Delete all chats.
- To delete one chat, open its three dot menu and choose Delete.
- Deleting chats does not erase ChatGPT’s memory. Clear memory separately under Personalization.
- OpenAI says deleted chats are scheduled for permanent removal within 30 days.
- Use Temporary Chat for conversations you do not want saved in your history.
Your ChatGPT history can fill up quickly, and it may hold personal or work details you would rather not keep. Clearing it takes less than a minute, but there are a few things that deleting chats does not do. This guide shows how to clear ChatGPT history on web and mobile, and how to handle memory and privacy settings too.
How to delete one ChatGPT chat
- Open ChatGPT and find the chat in your history list.
- On desktop, hover over the chat and click the three dots. On mobile, press and hold the chat.
- Choose Delete and confirm.
If you only want to hide a chat, choose Archive instead. Archived chats move out of your main list but stay saved, and you can bring them back later.
How to delete all ChatGPT chats
- Open your profile or name (bottom left on web).
- Go to Settings, then Data controls. On mobile, Data controls may open directly from your profile menu.
- Next to Delete all chats, click Delete all and confirm.
OpenAI warns this cannot be undone, and it can also affect chats inside projects. Menu labels differ slightly between devices and app versions, so look for “Data controls” if you cannot find the exact wording. If you would rather keep your chats, choose Archive all chats from the same menu.
How to clear ChatGPT history on iPhone and Android
The steps are almost the same in the app. Press and hold a chat to delete it. To remove everything, tap your profile or name, open Data controls, and choose Delete all chats. The labels may look different depending on your phone and the app version.
Does deleting chats clear ChatGPT memory?
No. Memory is a separate setting. Reports say ChatGPT can still remember facts about you after you delete every chat. To clear it:
- Go to Settings, then Personalization, then Memory.
- Delete individual memories, clear all memory, or turn memory off.
One February 2026 guide describes two switches here: Reference saved memories and Reference chat history. Turn both off if you want ChatGPT to stop drawing on past conversations. Your menu may show different wording, so check what your version offers.
How long until deleted chats are really gone?
OpenAI says deleted chats are scheduled for permanent removal from its systems within 30 days. There are exceptions: chats that were already de-identified and disconnected from your account, and chats OpenAI must keep longer for security or legal reasons. So “delete” does not mean “gone this second,” even though the chat disappears from your list right away.
Use Temporary Chat to avoid saving history
If you do not want a conversation in your history at all, start a Temporary Chat. Open a new chat and turn on Temporary Chat with the speech bubble icon at the top right. These chats do not appear in your history and are not used for future chats. One guide notes they may still be stored for up to 30 days.
Stop your chats from training the model
Deleting a chat is not the same as opting out of training. One guide says you can turn off the setting that lets your content improve the model under Settings, then Data controls, and that it applies to future chats only. Check your own Data controls screen, because the wording can change.
