Back up your Claude chats before deleting them (2026)

Claude lets you delete one conversation, a selection, or all of them. Anthropic says a deleted conversation is removed from your chat history immediately and deleted from its back-end systems within 30 days (Claude Help Center). Its privacy center adds that chats may be kept longer when required by law, to resolve disputes, or to combat Usage Policy violations, and that chats flagged by its trust and safety systems are kept for up to 2 years (Anthropic Privacy Center). There is no undo in your account, so keep a copy of anything you might want again first.

1. Request Anthropic's data export

On the web app or Claude Desktop, go to Settings, Privacy and click Export data. It can't be started from the iOS or Android app. Anthropic emails a download link to your account address; you must be signed in to use it, and the link expires 24 hours after it is created and may work only once, so download it right away (Export your Claude data).

Anthropic says the export includes your conversation data and account data, but not the original files you uploaded, so keep your own copies of those. On Team or Enterprise plans, the button only appears if an owner has allowed members to export. We have not tested the contents of Anthropic's export, so this page does not describe its format.

2. Save the chats you'll reread as Markdown

For the conversations you care about, a readable copy helps. ThreadVault (disclosure: we make it) is a Chrome extension that exports chats from your signed-in claude.ai tab as Markdown plus JSON, built in your browser so your chats never touch our servers.

1. Open claude.ai in Chrome and sign in.
2. For one chat: open it, click the ThreadVault icon and choose Export this chat. You get one Markdown file.
3. For many: click Bulk export, then Check connection and Refresh library, tick the chats you want (or Select all shown), and export. You get one ZIP named like ThreadVault-claude-2026-11-13.zip.
4. Unzip it into a dated folder such as claude-backup-2026-11/. Inside, a claude/ folder holds a Markdown file and a matching JSON file for each chat, and manifest.json lists what was exported and any chat that could not be read.

Each Markdown file starts with YAML frontmatter (title, dates, source: claude and the chat's url), then the conversation as ## You and ## Claude sections in page order. We tested single-chat and bulk export on a real Claude test account on 12 November 2026: the visible text, turn order and code blocks came through, and the ZIP held the manifest plus a .md and a .json for each chat. Images, uploaded files, artifacts and Projects were not part of that test, so don't rely on ThreadVault for those.

3. Check the backup

Open a few files, including your longest chat, and make sure the answers and code are there. Compare manifest.json with the chats you meant to keep. Only then delete.

4. Delete

• One chat on claude.ai: find it in the left sidebar or under Chats and tasks, hover, click ⋮, choose Delete, then Delete again to confirm.
• Several or all on claude.ai: click Chats and tasks, hover over a chat, click ⋮, then Select. Tick more chats or click Select all, then Delete twice.
• iOS: touch and hold a chat in your list and tap Delete, or tap ⋯ in an open chat. Android: tap ⋮ in an open chat, or use the checklist icon in your chat list to delete several.

Deleting chats does not delete your projects or account information; Anthropic keeps those until you delete them or your account. Deleting your account is permanent and you can't recover the account or its conversations (Delete your Claude account), so export before you do that too.

Training and deleted chats

If you allowed Anthropic to use your chats to improve Claude, it says it may keep that data in a de-identified form for up to 5 years in its training pipelines, and that a chat you delete from your history won't be used to train future models (Anthropic Privacy Center).

Steps and retention facts are from Anthropic's Help Center and Privacy Center as checked on 13 November 2026. Menus change now and then, so follow what the app shows.

Pricing
