Cookie Policy
Effective date: 1 February 2026 Last updated: 24 February 2026
This Cookie Policy explains how The Vanderbilt Portfolio AG (“we”, “us”) uses cookies and similar tracking technologies on zugdlt.com (the “Site”). It should be read alongside our Privacy Policy.
What Are Cookies?
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites function correctly, to remember your preferences, and to provide information to the site operator. Similar technologies — including web beacons, pixels, and local storage — serve comparable purposes and are covered by this policy.
The Four Categories of Cookies We Use
Category 1: Strictly Necessary Cookies
These cookies are essential for the Site to function. They cannot be disabled. They do not require consent.
| Cookie | Purpose | Duration |
|---|---|---|
| Cookie consent preference | Remembers your cookie consent choices | 12 months |
| Session security | Protects against cross-site request forgery | Session |
Strictly necessary cookies do not track you across sites and do not carry any advertising function.
Category 2: Analytics Cookies
These cookies help us understand how visitors interact with the Site — which pages are popular, how long visitors stay, and where they come from. This helps us improve editorial content and Site performance. Analytics cookies require your consent where required by applicable law.
Google Analytics
We use Google Analytics, provided by Google LLC. Google Analytics sets the following cookies:
| Cookie | Purpose | Duration |

_ga | Distinguishes users; generates statistical data on site usage | 2 years |
_ga_[ID] | Maintains session state for Google Analytics 4 | 2 years |
_gid | Distinguishes users | 24 hours |
_gat | Throttles request rate | 1 minute |
IP addresses are anonymised before storage. Google Analytics data is used solely for internal analytics and is not shared with third parties for advertising purposes beyond Google’s standard data processing terms.
You can opt out of Google Analytics across all websites using the Google Analytics Opt-out Browser Add-on available at tools.google.com/dlpage/gaoptout.
Category 3: Advertising Cookies
These cookies are used to serve advertisements relevant to you and to measure the effectiveness of advertising campaigns. Advertising cookies are set by Google Ad Manager and its advertising network partners. They require your consent.

- Serve advertisements based on your previous visits to this and other websites
- Limit the number of times you see a particular advertisement
- Measure the effectiveness of advertising campaigns
- Report on advertisement interactions

Category 4: Functional Cookies
Functional cookies remember your preferences to improve your experience on the Site — for example, your preferred reading settings. We do not currently use functional cookies beyond those described above, but we reserve the right to introduce them, at which point this policy will be updated.
