Your data (documents, conversations, settings) is retained for 90 days after deactivation. You can reactivate at any time during this retention period at Settings → Billing.

All invoices are available under SettingsBillingInvoices:

  • Download PDF invoices for any past billing period
  • Each invoice includes itemized usage, plan charges, and any overage fees
  • Invoices are also sent automatically to your billing email address after each renewal

If your usage exceeds the plan limits within a billing cycle, overage fees apply at the end of the cycle:
