Summary: this service is stateless and stores nothing. No database, no accounts, no cookies, no analytics.
Request parameters — the invoice fields (buyer RUC/name, line items, IVA rates), and your bring-your-own FacturaSend credentials (x-facturasend-tenant, x-facturasend-key) sent as HTTP headers — are used in memory only to compute the local IVA totals and forward the call to FacturaSend, which generates, digitally signs and transmits the Documento Electrónico to the government SIFEN / e-Kuatia (DNIT) system, then discarded. The signing and SIFEN transmission happen inside the merchant's own FacturaSend account; this server never signs, never holds the digital certificate, and never persists the API credentials. Invoice data is processed and stored by FacturaSend and the DNIT 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.
