Summary: this service is stateless and stores nothing. No database, no accounts, no cookies, no analytics.
Request parameters — the invoice line items (create) or the merchant-signed invoice XML (publish), and your bring-your-own MISA meInvoice credentials (x-meinvoice-token, x-meinvoice-taxcode) sent as HTTP headers — are used in memory only to forward the create / publish / status call to the MISA meInvoice gateway, then discarded. The invoice is signed on your side with your own digital signature (chữ ký số / USB Token); this server never signs, never holds a certificate, and never persists the token or tax code. Invoice data is processed and stored by MISA meInvoice and the General Department of Taxation (Tổng cục Thuế) under the merchant's own taxpayer context. The host (Vercel) keeps short-lived HTTP logs per its privacy policy; credential headers are never logged by the application.
Because nothing is stored, there is nothing to delete or export.
