They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work. These cookies do not store any personally identifiable information.

Plausible Analytics — We use Plausible Analytics to measure and continuously improve the performance of our OKW website. With your consent, we collect anonymised usage data. This enables us to track which pages are visited and how visitors navigate the website. For this statistical analysis, your IP address is processed only briefly when you access a page; it is immediately anonymised and not stored. This processing takes place exclusively with your express consent, which you may withdraw at any time. Further information can be found in our privacy policy. Cookies: The provider does not set any cookies of its own.

The OKW website uses the Google Analytics tracking code. With your consent, usage data collected by Google may be linked to your Google account. This allows website usage, advertising effectiveness and conversion data to be analysed across devices and enables the optimisation of personalised advertising. This will only take place with your express consent and may be withdrawn at any time. These cookies enable us to count visits and traffic sources so that we can measure and improve the performance of our website. They help us answer questions such as which pages are most popular, which are used least, and how visitors navigate the website. All information collected by these cookies is aggregated and is therefore anonymous to OKW.

These cookies may be set through our site by our advertising partners. They may be used by those companies to build a profile of your interests and show you relevant adverts on other sites. They do not store directly personal information, but are based on uniquely identifying your browser and internet device. If you do not allow these cookies, you will experience less targeted advertising.

These cookies and services are used to display interactive maps from Google Maps.

We use a third-party service (flyeralarm) to integrate the online flip-through catalogue. To display the catalogue, a connection is established with flyeralarm's servers. In doing so, your IP address is transmitted to FLYERALARM. If you do not allow this category, the catalogue will be replaced by a placeholder and will only be loaded once you have given your explicit consent.
