After Matomo consent is revoked, a functional cookie can also store the rejection. Further settings are in the local browser storage, not in cookies.

Depending on the function, the associated personal processing is based on Article 6 (1) (b) or (f) of the GDPR. The explains in more detail Privacy Policy.

Cookies & local browser storage

The following overview describes the website integration as of November 11, 2026. Cookies are transmitted to the associated server when appropriate requests are made. Local storage is in the browser and is not automatically sent with HTTP requests.

The storage processes required for the requested functions serve to provide the website securely and to implement your selection (§ 25 Para. 2 No. 2 TDDDG). Optional statistics are only activated after consent. You do not have to allow Statistics to contact us or post comments.

Matomo: Statistics without analysis cookies

Matomo is activated on this website; the analysis server is matomo.grittmann.media. Vor Ihrer Zustimmung werden weder das Matomo-Script geladen noch Statistik-Anfragen gesendet. Auch nach Zustimmung bleiben Analyse-Cookies durch disableCookies disabled. The usual Matomo cookies _pk_id.* und _pk_ses.* are not required by the current integration. Any old stocks of these analysis cookies will be removed when you access the active consent control.

Despite analysis cookies being deactivated, connection and usage data are processed if statistics are permitted, in particular the IP address, technical browser information and the page accessed. Matomo is operated on a server in Germany. The IP address is shortened by two bytes on the analysis server before storage. Form content, URL parameters and confirmation tokens are not transmitted. The legal basis for the optional statistics is your consent in accordance with Article 6 (1) (a) GDPR.

You can give your consent directly in Matomo section of the privacy page withdraw with effect for the future. The lawfulness of the processing carried out up to that point remains unaffected. Clearing your browsing data will remove local choice and cookie entries, but not data already stored on the analytics server.

Your display preference

If you select a display mode using the sun or moon symbol, we will save your choice as grittmann-theme in your browser’s local storage. This means the desired light or dark mode is retained the next time you visit. The setting is not transmitted to our server or to third parties and remains stored in the browser until the website data is changed or deleted. Without making our own selection, we use light mode.

Your options

You can view, delete or block cookies in your browser settings. Without a session cookie, login and protected forms do not work reliably. Public information pages remain readable.

The website does not use marketing cookies. If Matomo is activated, a selection for optional statistics appears. Matomo will not be loaded without consent. The integration does not set any analysis cookies. You can activate an external OpenStreetMap map separately on the contact page. The map is not loaded before activation; When you close it, the integration is terminated. The card provider processes technical connection data and can use its own storage technologies. Please see our for details Data protection information. Falls künftig Statistik-, Marketing- oder andere optionale Dienste hinzukommen, müssen diese vor einer erforderlichen Einwilligung blockiert und Ablehnung, Auswahl sowie späterer Widerruf ermöglicht werden.
