Terms of Use

What Marco Três is

A useful-information service for the Triple Frontier — news, guides and live data, AI-curated with editorial oversight by Annie Grellmann. The content is informational.

Accuracy and liability

We work for accuracy and cite the source of every figure and guide. Still, prices, hours, exchange rates, rules and attraction status change — always confirm with the official source before decisions (travel, purchase, border crossing).

Forecasts and estimates (predicted flow, rainbow chance) are decision support, not guarantees. Marco Três is not liable for losses arising from decisions based on the content.

Intellectual property

Content produced by Marco Três belongs to Marco Três/INFI Comunicação. Third-party content is credited and linked to its source. You may share with credit and a link; full reproduction without authorization is not permitted.

Third-party links and services

The site contains external links, including affiliate links (e.g. flight search via Travelpayouts). We do not control or take responsibility for third-party sites.

Sending messages

By sending a correction, suggestion or contact message, you declare you have the right over what you send and authorize its use to improve the content. See how we handle your data in the Privacy Policy.

Availability

The service is provided "as is". There may be interruptions, maintenance or temporary unavailability, without prior notice.

Changes

We may update these Terms. The date at the top shows the last revision; continued use after changes means acceptance.

Law and jurisdiction

The laws of Brazil apply. The courts of Foz do Iguaçu (PR) are chosen for matters relating to these Terms. Contact: 3xmarcotres@gmail.com.
