Your privacy settings

How your choice is saved
We store your choice, its time and the version of these settings locally in your browser for a maximum of 180 days. This does not create a random visitor identifier. On another device or after deleting website data, you choose again.
Withdrawing permission stops further statistics requests, deletes accessible Matomo cookies and removes embedded Spotify players. It cannot retrieve data already transmitted or information stored by a provider on its own domain. The training apps may store necessary settings and offline files locally; withdrawing permission does not delete these. They contain no Google tags loaded through this website.
Links to social media, WhatsApp and maps only open the respective provider when you click them. Read the full privacy notice →
Basic statistics without a visitor identifier
We also count page views directly on our server. We store only daily totals for each public page visited and totals for explicitly approved campaign values. We do not set statistics cookies, read device characteristics using an analytics script or assign a visitor or session identifier for this purpose. The count does not link views into an individual visitor journey.
IP addresses, complete browser identifiers, referrer addresses, freely entered search terms and form entries are not stored in these basic statistics. The browser identifier transmitted with the HTTP request is only used briefly to filter recognisable automated requests. Totals are deleted after 24 months. Separately, the hosting provider processes technically necessary server logs as described in the hosting section.
The aggregated figures help us assess website use and content. To the extent that personal connection data is processed to receive and technically filter requests, we rely on our legitimate interest in data-minimising audience measurement (Article 6(1)(f) GDPR). Information about your right to object is available in the privacy notice. These stored totals cannot identify individual people again.
The ‘Website statistics’ choice controls the more detailed Matomo recording of page journeys and contact clicks. It remains disabled until you consent. Anonymous counting on the server is independent of this choice.
