Cookie Policy
Last Updated: January 9, 2026
This Cookie Policy explains what cookies are, how we use them on our website, and how you can manage your cookie preferences.
What are Cookies?
Cookies are small text files that are stored on your device (computer, tablet, or mobile device) when you visit a website. Cookies are commonly used to make websites work or work more efficiently, as well as to provide reporting information. Cookies can be 'session cookies' (deleted when you close your browser) or 'persistent cookies' (remain on your device until they expire or are deleted).
Types of Cookies We Use
We use the following types of cookies on our website:
Necessary cookies: These cookies are essential for the website to function properly. They cannot be disabled. These include, for example, cookies that store your cookie consent preferences.
Analytics cookies: These cookies help us understand how visitors interact with our website by collecting and reporting information anonymously. These cookies are only set if you consent to their use.
Cookie Management
You can manage your cookie preferences in several ways:
- Via the cookie banner: When you first visit our website, a cookie banner appears where you can accept all cookies, customize your preferences, or reject non-essential cookies.
- Via cookie settings: You can change your cookie preferences at any time via the cookie settings link on our website.
- Via browser settings: You can also manage cookies generally via your browser settings. Most browsers allow you to block all or certain cookies or delete already stored cookies. Please refer to your browser manufacturer's instructions for details (e.g., you can usually find the options under 'Settings > Privacy > Cookies'). You can also set cookies to be automatically deleted when you close the browser.
Please note: If you block all cookies, the use of our website may be impaired. Some functions (especially those that are technically necessary) may then no longer work correctly. For example, the temporary storage of your cookie selection itself depends on a cookie. We therefore recommend rejecting or selectively deleting only optional cookies in the browser, rather than disabling all cookies across the board.
Withdrawal and Consent History
Withdrawal of your consent: If you have given us consent to use non-necessary cookies (e.g., Analytics), you can withdraw this consent at any time. You have the following options:
- Open the cookie settings again via the corresponding link on our website and deactivate the relevant categories there (e.g., 'Statistics').
- Delete the cookies via your browser. As soon as the consent cookie is deleted, our banner will appear again when you next load the page and you can make a new selection.
- Contact us informally (e.g., by email), and we will manually take your withdrawal into account, e.g., by no longer considering your analytics data on the server side.
The withdrawal of consent only applies to future data processing – data already collected may still be present in aggregated statistics, but anonymously and without personal reference.
Consent History
Our cookie consent tool logs when and which consent you have given or changed. This serves proof purposes (Art. 7 para. 1 GDPR) and is stored in compliance with data protection. These log entries contain, for example, a timestamp, information about your browser (as a hash) and the selection options made. Upon request, we can inform you which preference we have stored for your device.
Details on Individual Cookies
Below you will find – for transparency – an overview of the most important cookies we use:
| Cookie Name | Provider | Purpose | Storage Duration | Requires Consent? |
|---|---|---|---|---|
| cookie_consent | Our Website (First-Party) | Stores your consent/rejection of cookie categories. Enables remembering your settings when browsing further. | 1 year | No (essential) |
| mjid (Mailjet Cookie) | Mailjet SAS (Third-Party) | Serves the integration and function of the newsletter form (Mailjet). Recognizes, for example, whether a user has already loaded a form. | 1 year | No (essential for newsletter function) |
| Analytics (no cookie) | Vercel Inc. | Anonymous session recognition for web analytics (hash from request, no cookie on device). Counts visits and page views. | Session (automatically discarded after 24h) | Yes (Statistics – only active with consent) |
Note: The above table lists the most important cookies as examples. Depending on the further development of our website, changes may occur. We update the list accordingly.
Legal Bases
The legal bases for the use of cookies result from the GDPR and the German TTDSG (Telecommunications-Telemedia Data Protection Act).
Essential cookies: are set on the basis of our legitimate interest (Art. 6 para. 1 lit. f GDPR) in a technically flawless and user-friendly operation of the website, and/or because they are necessary to provide the service you have expressly requested (§ 25 para. 2 no. 2 TTDSG). No consent is required for these cookies.
Non-essential cookies (Analytics): are only set with your consent (Art. 6 para. 1 lit. a GDPR in conjunction with § 25 para. 1 TTDSG). If you have not given consent, these cookies remain disabled and no corresponding data is collected.
We inform you in our cookie banner in clear and simple language about the type and purposes of the cookies we use, so that your consent can be informed. Pre-checked boxes are not used by us – you actively choose your preferences (opt-in). You have full freedom of choice; a refusal of consent has no influence on the basic usability of our website.
Further Information
For further information on how we handle personal data, please refer to our Privacy Policy. Should you have questions or concerns regarding our use of cookies, you can contact us at any time (contact details see Imprint or Privacy Policy). We are happy to help.
