Security is part of the workflow.
Not decoration.

FinanceConvert processes uploaded financial files in volatile memory (RAM) and explicitly removes them after download or expiry. The payload never touches a permanent disk.

// File loaded directly into volatile RAM
fileStore.upload(buffer, filename)
// Output streamed to client
fileStore.delete(temp_id) // ← on download
// Nothing written to disk. Ever.

Authentication uses securely hashed passwords and signed session tokens. Account, quota, history, and billing states are backed by PostgreSQL, holding only metadata — never file contents.

All data in transit is encrypted via TLS 1.2 or higher. File buffers are isolated per request and inaccessible to other sessions.
