Data privacy notes on social plugins

Our website uses social plugins (“plugins”) from social networking sites such as Twitter, Facebook etc.

If you access a Alfred Herrhausen Gesellschaft website using such a plugin, your browser will contact the server of the underlying social networking site, load the visual presentation of the plugin, and present it to you. While this is happening, the social networking site receives information concerning your visit to our website, as well as further data such as your IP address.

In order to ensure an appropriate level of data privacy in connection with our internet presence, we have deactivated the respective plugins with a button and placed a short data privacy note that can be consulted before a plugin is activated.

We have no influence on the amount of data that social networking sites collect via an active plugin. For more information, please consult the relevant data privacy notice:







In view of the importance of data privacy, and our obligations of transparency, we provide information below about cookies, how we use them on our website and what options you have if, despite the benefits they bring, you prefer to disable them. We will assume you agree to accept the cookies that we use on our website if you do not disable or opt out of them as described below.

What are cookies?
Cookies are small text files. They are commonly downloaded to your computer or mobile device by websites that you visit. They enable the website to tag your device and recognize it as you move around the site (and potentially when you return at a later date) so that, for example you do not have to re-enter your password each time you move between pages of the website.

When trying to understand cookies, and how to control them, it can help to know some terminology:

  • Cookies installed on your device by the organization running the website you are visiting are known as “first party” cookies.
  • Cookies installed on your device via the website you are visiting by another organization are termed “third party” cookies. An example is a cookie set by a specialist website analytics company that provides the website owner with data on the numbers of people visiting its website.
  • So-called “persistent cookies” remain on your device even after you close your internet browser. They are activated each time you visit the website that created that particular cookie. For example, where a "persistent cookie" is used on a website to remember your login details, you will not need to enter those details each time you visit that website.
  • Session cookies, by contrast, are temporary and are typically used to enable the website to operate, e.g. by permitting a user to move from page to page without having to log in again. Once you close your browser, all session cookies are deleted.

What cookies do we use?

To enhance user experience, this website uses ‘persistent’ and ‘session’ cookies for the purposes described below. These cookies are generally ‘first party’ cookies, but may also be ‘third party’ cookies.

  • Website functionality
    Cookies that are essential for our website to function technically or which provide a service or option that you have requested. For example, a cookie that “remembers” your authentication details so you can remain logged into secure internet banking facilities, or a cookie that remembers the country or language you have selected.
  • Website performance analysis
    Cookies that help us improve our website by providing us with aggregate statistics on how many users visit it, which parts of the site are viewed the most, and the city or regional location of those users. A third party analytics provider under a contract may install these with us. These cookies do not identify you personally. Nevertheless, if you prefer to opt out of such analytics cookies, you may do so here: “Opt Out” and a cookie will be stored under this name. No information is collected as long as the cookie is stored in your browser. Please keep in mind that – as soon as the cookie is erased – the Opt Out for Alfred Herrhausen Gesellschaft’s website is disabled and must be renewed.
    Currently, Opt Out is active: tracking information is not being collected on this computer. To reactivate collection of tracking information, please click here

Aside from any specific opt-outs we have provided above, if you do not wish to receive cookies you can set your web browser to disable cookies. Note that most browsers offer different levels of privacy, such as allowing first party cookies but blocking third party cookies, or notifying you each time a website wants to install a cookie. Be aware that disabling cookies in this way will prevent new cookies from being set, but will not stop previously set cookies from operating on your device unless you delete all cookies in your browser settings.
