Summary: this service is stateless and stores nothing. No database, no accounts, no cookies, no analytics.
Request parameters — the base64 signed comprobante electrónico v4.4 XML, its clave and fecha, the emisor/receptor identification, and your bring-your-own ATV API credentials (x-hacienda-username, x-hacienda-password) sent as HTTP headers — are used in memory only to exchange for a short-lived OAuth token and forward the /recepcion submission to the government Ministerio de Hacienda gateway, then discarded. The comprobante is already signed on your side; this server never signs, never holds your Hacienda certificate, and never persists the API credentials. Invoice data is processed and stored by Hacienda 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.
