Terms.

This site presents the ZENUM 1:1 and RUBEN, working software in beta, by KULTR Unipessoal Lda, Estrada Nacional 10, Edifício Jardim Parque, 2615-129 Alverca do Ribatejo, Portugal. The ZENUM 1:1 is not yet on sale; nothing on this site is an offer for sale.

“Reserve your spot” is a free, non-binding expression of interest. You give us an e-mail address; we tell you when the ZENUM 1:1 can be ordered. No payment is taken, no contract is formed, and you may withdraw at any time by replying “remove”. Your data is handled as described in the Privacy notice. You must be 18 or older, or 21 where the applicable law requires it.

Terms of sale will be published here before ordering opens. They will give you, at a minimum, the rights Portuguese and European consumer law provides: complete pre-contract information, a 14-day right of withdrawal, and a three-year legal guarantee of conformity.

RUBEN is an AI. It can be wrong. It is not a source for safety-critical, emergency, medical, legal or financial decisions. In a car, RUBEN is read-only: it cannot steer, brake or operate the vehicle. Full transparency information is on the AI Act & data protection page.

RUBEN is in beta: specifications, features and dates may change before launch. Texts, images and renders are protected; press use is described on the Press page.

These terms are governed by Portuguese law, without prejudice to the mandatory consumer protection of the country where you live.
