Terms of use

Who runs the site

This site is run by Marta Matos, a self-employed professional trading as Zeno, in Lisbon. Contact: marta.matos@withzeno.com.

What is on the site

The texts explain what we do and are not an offer. The terms of each project (scope, timeline and price) are always put in writing before we start.

The cases are anonymised to protect our clients. The numbers come from the clients’ own measurements or from the systems we built. When a number is a target or an estimate, we say so.

Rights to the content

The texts, diagrams and logo belong to Marta Matos. You may quote short extracts, with a link to the original page. For any other use, ask us for permission.

Links to other sites

When we link to third-party sites, we are not responsible for their content.

Liability

We do our best to keep the information correct and up to date, but we do not guarantee that it is always complete. The site may be unavailable from time to time, for maintenance or because of technical faults.

Governing law

These terms are governed by Portuguese law.
