This site uses SSL encryption for security purposes and to protect the transmission of sensitive content, such as logging into the members' only area, orders or requests you send to us as the site operator.

  1. Data collection on our website


The internet pages partly use so-called cookies. Cookies do not harm your computer and do not contain viruses. Cookies serve to make our offer more user-friendly, effective and secure. Cookies are small text files that are stored on your computer and stored by your browser.

Most of the cookies we use are so-called "session cookies". They are deleted  automatically when you leave our website. Other cookies remain stored on your device until you delete them. These cookies allow us to recognize your browser the next time you visit.

You can adjust your browser to inform you on the setting of cookies and permit cookies in particular only, the acceptance of cookies for certain cases or generally disallow them as well as the activation of automatic deletion of cookies when closing the browser. Disabling cookies may limit the functionality of this website.

Cookies which are required to carry out the electronic communication process or to provide certain functions which you wish to have (e.g. orders, login to the members' only area) are stored on the basis of Item 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in the storage of cookies for the technically error-free and optimized provision of its services. If other cookies are stored (e.g. cookies to analyze your surfing behavior), these will be treated separately in this privacy policy.

Server log files

The provider of this website automatically collects and stores information which your browser transmits automatically to us in so-called server log files. These are:

  • Type of browser and version
  • Operating system
  • Referrer URL
  • Host name of the accessing computer
  • Time of server request
  • IP-address

A consolidation of data with other data sources is not performed.

The basis for data processing is item 6 para. 1 lit. f GDPR, which allows for the processing of data for fulfillment of a contract or pre-contractual provisions.

Contact form

If you send us inquiries via the contact form, your details from the contact form, including the contact details you provided there, will be stored in order to process your request and in case of follow-up questions. We will not share your data without your consent.

The processing of the data entered into the contact form therefore is based solely on your consent (item 6 (1) lit. GDPR). You can withdraw this consent at any time. An informal message by e-mail to us is sufficient. The legitimacy of the data processing carried out until the withdrawal remains unaffected by the cancellation.

The data entered by you in the contact form will remain with us until you ask us to delete it, revoke your consent to the storage or the purpose for the data storage is inapplicable (e.g. after completion of your request). Mandatory legal regulations - especially retention periods - remain unaffected.


Some of our offers are available to ZELLCHEMING members only. To access them, one must first log in by entering username and password for authentication.

In the event that a member forgot their password, a new password can be requested by using the "Forgot password?" button. To recover the account the e-mail address must be entered.

  1. Newsletter

Newsletter information

With our newsletter we inform you about us, our offers and events.

If you would like to receive the newsletter, we need a valid email address from you as well as information that allows us to verify that you are the owner of the specified email address or that the owner agrees to receive the newsletter. Further data is not collected. These data are used for sending the newsletter only and will not be disclosed to third parties.

When subscribing to our newsletter, your IP address and the date of registration is stored. The sole purpose of this storage is in case of third party abuse of an e-mail address and newsletter subscription without the knowledge of the entitled person.

The processing of the data entered into the newsletter registration form takes place exclusively on the basis of your consent (item 6 (1) lit. GDPR). You may revoke your consent to the storage of data, e-mail address and its use for newsletter transmission at any time, for example via the "unsubscribe" link in the newsletter or by notifying us via the above-mentioned contact options. The legitimacy of the data processing carried out until the withdrawal remains unaffected by the cancellation.

The provided data for the purpose of the newsletter subscription will be saved by us until you unsubscribe and will be deleted after unsubscription from the newsletter. Data stored with us for other purposes (e.g. members' e-mail addresses) will remain unaffected.

Our website uses plugins from YouTube, operated by Google. Site operator is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA.

Google Web Fonts

This site uses so-called web fonts, provided by Google, for the consistent representation of fonts. When you request a page, your browser loads the required web fonts into your browser cache to display texts and fonts correctly.

For this purpose the browser you use must connect to Google's servers. As a result, Google learns that our website has been accessed via your IP address. The use of Google Web Fonts is in the interest of a consistent and attractive presentation of our online services.
