Cookie Policy
Last updated: 12/11/2026
This Cookie Policy explains how DATA DRIVEN DYNAMICS, UNIPESSOAL LDA (ZONA FRANCA DA MADEIRA) uses cookies and similar technologies (such as local storage and pixels) on this website.
What cookies are
A cookie is a small text file that your browser stores on your device. Some cookies are necessary for the website to work. Others help us understand how the website is used, measure the success of our ads, or correctly attribute a visit that leads from our website to a provider.
How we use cookies
- Strictly necessary – required for the website to work, to be delivered securely and to remember your cookie choices. These cookies are set without consent because the website cannot function without them.
- Statistics – help us count visits and see which comparisons are useful (Google Analytics 4). Only with your consent.
- Marketing – measure whether a click on our ads on Google or Bing led to a visit and a click-through to a provider (Google Search Ads 360, Google Ads, Microsoft Advertising). Only with your consent.
- Partner tracking – when you move on to a provider, your visit is attributed to us via a pseudonymous click ID. The provider may also set cookies for this purpose on its own website; its privacy policy applies to those. This is how we are paid – see our Advertising Disclosure for details.
Your choices
On your first visit, we ask which non-essential cookies you allow. All categories except “Strictly necessary” are switched off by default, and you can reject them with a single click. You can change or withdraw your choice at any time using the “Cookie Settings” link in the footer. You can also delete or block cookies in your browser settings; if you block strictly necessary cookies, parts of the website may not work.
For more information on how we handle personal information, retention periods and your rights, see our Privacy Policy.
