Cookie Policy
This Cookie Policy explains what cookies and similar technologies are, how the DIEFI2 project website (diefi.eu) uses them, and what choices you have regarding their use. This policy should be read alongside our Privacy Policy.
What Are Cookies?
Cookies are small text files that are placed on your computer or mobile device when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and supply information to the website owners.
Cookies can be "session" cookies (deleted when you close your browser) or "persistent" cookies (remain on your device for a set period or until you delete them).
How We Use Cookies
We use cookies and similar technologies for the following purposes:
- Essential functionality — to store your consent choice, language preference, and, where applicable, a secure session only in the restricted admin area
- Analytics — to understand how visitors use our website and improve it, through Google Analytics 4, only with your consent
- Optional preferences — to store optional interface settings locally in your browser, such as reduced motion and text size, only if you allow it
Your Consent
When you first visit our website, a cookie consent banner is displayed. You can choose to:
- Accept All — enables all cookies including analytics
- Reject All — only strictly necessary cookies are used
- Customise — choose which categories of cookies to allow via Cookie Preferences
Continuing to browse the site does not count as consent. Non-essential cookies and similar technologies are only activated after you select Accept All or Save Preferences.
We implement Google Consent Mode v2, which means:
- Analytics cookies are blocked by default until you give explicit consent
- No tracking data is sent to Google until you accept analytics cookies
- If you reject or revoke consent, all Google Analytics cookies are deleted and tracking stops immediately
- Your consent choice is stored for 6 months and can be changed at any time
