Legal Notice

Last updated: 9 November 2026

This is a translation for convenience. The Portuguese version prevails in case of doubt.

1. Service provider

The f3st.pt website and the F3ST service are operated by:

  • Name: Sérgio Tiago Gomes Serra, sole trader (empresário em nome individual)
  • Tax ID (NIF): 244831726
  • Address: Avenida do Atlântico, n.º 644, 4900-348 Viana do Castelo, Portugal
  • Email: geral@f3st.pt

"F3ST" is the trade name under which the service is provided. As the provider is a sole trader, there is no company registration number or share capital to state.

2. Activity

F3ST is software for managing consumption at events (cashless payments with NFC cards), provided to event organizers acting in the course of their business. F3ST is not a payment institution and does not hold end customers' funds: payments are received by the organizer or processed by an authorised payment service provider, as set out in the Terms of Service.

Invoices for the sales made at each event are issued by the organizer from its own certified invoicing software account, under its own tax ID and series. F3ST does not issue invoices to organizers' customers in its own name.

3. Who the service is for

The service is for businesses only. Anyone attending an event who has a question about a purchase, a payment or an invoice should contact the organizer of that event, who is the seller and the controller of the data collected at the event.

4. Intellectual property

The software, design, texts and images of this website and of the F3ST platform belong to the provider named above or are used under licence. They may not be copied, modified or distributed without written permission, except where the law allows it. Logos, names and content of the organizers using F3ST belong to them.

5. Complaints book

Complaints may be filed through the Portuguese Livro de Reclamações Eletrónico. Replies are sent to the email given by the complainant.

6. Personal data and cookies
