Claude how to delete chats: open claude.ai, hover over a chat in the sidebar, click the three-dot menu and choose Delete.

Anthropic's Help Center guide covers each step, and there is no single "delete everything" button for chats.
A deleted chat disappears from your history immediately. Anthropic says it is removed from its back-end systems within 30 days. This article describes the consumer plans (Free, Pro and Max) as of November 4, 2026.
How to delete one chat on the web
- Open claude.ai and find the chat in the left sidebar, or open "Chats and tasks" to see your full history.
- Hover over the chat and click the three-dot button on the right.
- Choose Delete and confirm in the prompt.
How to delete one chat on iPhone or Android

On Android, open the conversation, tap the three-dot menu in the top right, tap Delete and confirm.
How to delete several chats at once
On the web:
- Click "Chats and tasks" in the left sidebar.
- Hover over any chat, click the three-dot button and select "Select."
- Tick the chats you want gone, or use "Select all" at the top.
- Click Delete and confirm.
On Android, open your chat list and tap the checklist icon in the top right. Tick each chat, tap the trash icon and confirm. The help article gives no bulk-delete steps for iOS.
Can you delete all Claude chats?
Only through "Select all" in the bulk list. The help article describes no separate delete-all-chats setting. The only way to remove all of your Claude data in one go is to delete your account. Anthropic says that is permanent, and neither the account nor its conversations can be recovered.
What happens to projects
Deleting chats does not touch your projects. Anthropic says projects and account information stay until you delete them or delete your account.
To delete a project, go to the Projects page, click the three dots in the project's upper right corner, select Delete and click "Yes, delete." Inside a project, click the three dots next to the star, select Delete and confirm. Archived projects can't be deleted, so unarchive one first. Anthropic's projects guide does not say what happens to a project's chats or files when you delete it. If you want to keep a chat, use the dropdown arrow next to its name to move it out of the project first.
How long Anthropic keeps deleted chats
Anthropic's privacy page, dated July 1, 2026, says deleted chats leave your history at once and are deleted from back-end storage within 30 days. It lists exceptions:
| Case | How long |
|---|---|
| Deleted chat, normal case | Removed from storage within 30 days |
| Chat flagged by safety systems as a Usage Policy violation | Inputs and outputs up to 2 years, classification scores up to 7 years |
| Thumbs up or down feedback and bug reports | 5 years |
| Chats used for model training, if you allowed it | De-identified, up to 5 years |
| Legal or dispute reasons | As long as required |
On training, Anthropic says that if you turn the setting off, your past and future chats are not used for future training, and deleted chats are not either. Data already inside training runs in progress, or in models already trained, stays. Incognito chats are never used for training.
Claude for Work and the API follow separate retention rules, covered in a different Anthropic article that the help center links to.
What to do next
Delete the chats you no longer want, then check your project list for old files. If you want training off, change the setting in your privacy options.
This guide is based on Anthropic's published help pages. Menu labels can differ slightly between app versions.
