Summary: this service is stateless and stores nothing. No database, no accounts, no cookies, no analytics.
Request parameters — the invoice number, buyer identity and line items, and your bring-your-own Leceipt API key (x-leceipt-api-key) sent as an HTTP header — are used in memory only to compute the VAT totals, assemble the document, and forward the create / job / file call to Leceipt (your own e-Tax service provider), then discarded. The digital signature and the Revenue-Department filing happen inside your own Leceipt account, where your certificate (CA — TDID/INET) lives; this server never signs, never holds a certificate, is not an authentication intermediary, and never persists the API key. Invoice data is processed and stored by Leceipt and the Thai Revenue Department under your own merchant context. The host (Vercel) keeps short-lived HTTP logs per its privacy policy; the API-key header is never logged by the application.
Because nothing is stored, there is nothing to delete or export.
