Summary: this service is stateless and stores nothing. No database, no accounts, no cookies, no analytics.
Request parameters — the invoice fields (buyer NIT/name, line items, IVA rates, your DIAN resolution number), and your bring-your-own Matias credential (x-matias-token) sent as an HTTP header — are used in memory only to compute the local IVA totals and forward the call to Matias API, which generates, digitally signs and transmits the factura electrónica to the government DIAN system under the modelo de validación previa, then discarded. The signing and DIAN transmission happen inside the merchant's own Matias account (a Software Propio direct-to-DIAN connection with no Proveedor Tecnológico middleman); this server never signs, never holds the digital certificate, and never persists the token. Invoice data is processed and stored by Matias and the DIAN under the merchant's own taxpayer context. The host (Vercel) keeps short-lived HTTP logs per its privacy policy; the credential header is never logged by the application.
Because nothing is stored, there is nothing to delete or export.
