Cookie Policy
Effective: 2026-11-12
This Cookie Policy explains how DATA DRIVEN DYNAMICS, UNIPESSOAL LDA (ZONA FRANCA DA MADEIRA) uses cookies and similar technologies (local storage, pixels) on this website.
What cookies are
A cookie is a small text file stored on your device by your browser. Some are needed for the site to work; others help us understand how the site is used or let our partners recognise a visit that came from us.
How we use them
- Essential — needed for the site to function and to remember your cookie choice. They are set without consent because the site does not work without them.
- Measurement — help us count visits and see which comparisons are useful. Set only with your consent.
- Partner tracking — when you click through to a partner, the partner may set a cookie to attribute your visit to us. This is how we are paid; it is described in our Affiliate Disclosure.
Your choice
On your first visit we ask which non-essential cookies you allow. You can change or withdraw your choice at any time from the cookie settings link in the footer, and you can delete cookies in your browser settings. Blocking essential cookies may stop parts of the site working.
