Summary: this service is stateless and stores nothing. No database, no accounts, no cookies, no analytics.
Request parameters — invoice data, and your bring-your-own SEF API key sent as an HTTP header (x-sef-api-key) — are used in memory only to build the UBL 2.1 SRB-CIUS XML and forward a request to the national SEF eFaktura REST API (as the official ApiKey header), then discarded. Invoices are processed and stored by the SEF system (Ministry of Finance) under the merchant's own fiscal identity and never persisted by this service. Your SEF API key stays under your control and is never stored. 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.
