Account Deletion

If you need to permanently remove your Thallus account and all associated data, you can request deletion from the Settings page. Deletion includes a 30-day grace period so you can change your mind.

Requesting deletion

Navigate to Settings → General and scroll to the Danger Zone at the bottom of the page. Click Delete Account to open the confirmation dialog.

Delete Account
This action cannot be undone. After a 30-day grace period, all your data will be permanently deleted.
The following will be deleted:
• All conversations and messages
• Uploaded documents and chunks
• Memories and preferences
• API keys and OAuth connections
• Workflows and execution history
• Team memberships
Enter your password to confirm

Delete My Account

For password-based accounts, you must enter your current password. For SSO-only accounts (no password set), type the word DELETE instead.

If you are the sole admin of a non-personal organization, you must either transfer admin rights or remove other members before you can delete your account.

30-day grace period

After confirming, your account enters a 30-day grace period. You'll receive a confirmation email with the scheduled deletion date.

Cancelling deletion

To cancel a pending deletion, simply log back in before the scheduled date. The deletion is automatically cancelled — no additional steps needed. The pending deletion flags are cleared on login, and your account returns to normal.

Your account is scheduled for deletion on March 24, 2026
To cancel, simply log back in before this date.

What gets deleted

When the grace period ends, a background task picks up your account and permanently deletes:

  • Conversations — all messages, attachments, and conversation metadata
  • Documents — uploaded files, processed chunks, and document synopses
  • Memories — all stored memories and preferences
  • API keys — all active and revoked keys
  • OAuth connections — all linked integration tokens
  • Workflows — all workflow definitions, versions, and execution history
  • Team memberships — removed from all organizations
  • Personal organization — deleted if no other members remain

Your Stripe subscription is automatically cancelled as part of the deletion process.

What's preserved (cold storage)

For legal compliance and trial abuse prevention, a minimal anonymized record is retained after deletion. This record contains no conversation content, documents, memories, or other user-generated data — only the minimum information required for audit trail integrity and abuse prevention.
