A direct line to nuViteo Labs.
Help with your purchase, download or a question about our content.
What to include
Email the address used for checkout, the approximate purchase date and a receipt or transaction reference if available. Tell us whether you need a download, billing correction, refund or content clarification. Do not send your full card number, security code, passwords or medical records.
What happens next
A person reviews your message. Our first-response target is 1–2 business days; it is not an automated resolution promise. A refund request sent within the 14-day window retains its request date while we locate the transaction.
Our scope
nuViteo Labs is an independent digital scientific publishing platform established in Brazil. This channel is not a medical consultation or an emergency service.
