The information generated by the cookie about the use of this Website by users is generally transmitted to a Google server in the United States and stored there. IP anonymization has been activated on this Website, so that Google will truncate the IP address of users beforehand within Member States of the European Union or other parties to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the United States and truncated there. On behalf of the operator of this Website, Google will use this information to evaluate the use of the Website by users, to compile reports on Website activity and to provide other services related to Website activity and Internet usage to the Website operator.

Further analysis – server data

In addition, information about the retrieved resources is stored on the application server. This storage includes software error logs to the extent corresponding errors occur. However, this storage does not include references to the incoming requests. In other words, these are anonymized data that are collected exclusively for the purposes of error detection and error analysis.

In order to ensure communication on the Internet and in particular access to the Website, it is necessary to collect certain data. This also includes the IP address of the user, without which a representation of the Website for the user would not be possible. This means that log files/server data are recorded when you visit the Website. The IP address is the basis for communication on the Internet. Other than for the goal of reliable communications, data are also stored that serve the purposes of data security, i.e. the protection of the systems, and are generally also used for the analysis of errors that occur. The so-called server data are stored by the provider of the website for reasons of communication and error detection.

Quintessenz Verlags-GmbH operates its websites through the company
1&1 Internet SE
Elgendorfer Str. 57
56410 Montabaur

With regard to the storage and erasure of this server data, reference is made to the current privacy policy of this provider, which you can find at the link

Except for anonymized statistical purposes, there is no further use of the log files / server data. In particular, no user profiles of guest visitors are created.

Provision of the Website

In principle, the Website can also be used anonymously without registering. With Quintessenz Verlags-GmbH, you have the option to register and create your own user account in order to facilitate follow-up orders and the use of the offered services. In this case, Quintessenz collects and stores the following mandatory information:

  • salutation, first and last name
  • User name (freely selectable)
  • Password
  • Email address

The provision of further information is voluntary. This means that you can optionally enter the following information when creating an account:

  • academic title
  • Customer number
  • Organization/university/company
  • Street and house number
  • Postcode and city
  • Country
  • Phone
  • Fax

Insofar as you have stored these data in an account, you can also modify them at any time and thus have full control over both mandatory information and voluntary information. In addition, you can have your account deleted at any time. The access data (login) of your account are generally valid for all online services of Quintessenz Verlags-GmbH. However, you alone decide which service is used and where you log in with your account.

If you create a user account, your email address will be verified by using a so-called double-opt-in procedure before being used by the controller. To this end, the user of the Website receives a confirmation email, which is sent to the email address specified during the registration process. The final storage of the specified email address takes place only after confirmation of a link provided with this email. If confirmation is not received within 30 days of placing an order, the email address is deleted by the controller.

The same procedure regarding the email is used to the extent you register for the receipt of a newsletter by email. This merely requires the specification of an email address. Email address, activation code and activation date are stored. You can unsubscribe from the newsletter at any time.

Registration for the “Quintessenz Newsletter” takes place via the linked URL, which is similarly operated by the above controller.

Depending on the respective product features and the selected payment method, it may be the case that you need to provide further data, in particular account or other payment data. If the payment method requires an external payment service provider, you may need to provide additional data to this provider or have already provided this when creating your account. In these cases, the privacy policy of the payment service provider applies. If necessary, this provides for the transfer of certain data to Quintessenz in the course of the payment transaction.

Should you not wish to create a user account, you can of course still place orders via the Website. In this case, the following mandatory information is required for processing:

  • Salutation, first name and last name
  • Street and house number
  • Postcode and city
  • Country
  • Email address
  • Product that you have ordered, including the data required for the performance of the contract (in particular product name, term, price, if applicable participant bookings for events in the event calendar, booking data).

The same applies when ordering digital products.

In addition to the mandatory information, there is also the option to provide further voluntary data about your person, such as deviating delivery addresses, your telephone and/or fax number for ease of order handling or to facilitate inquiries. Insofar as you have stored these data in an account, you can also modify them at any time and thus have full control over both mandatory information and voluntary information. In addition, you can have your account deleted at any time.

Your consent to the general terms and conditions and the privacy policy will also be stored, as they represent an essential requirement for the use of the portal and thereby grant consent to the data use or document that information of the data subject has been provided in accordance with the data protection regulations. Specifically, the timestamp (time of consent) and possibly consent identifier are stored for this purpose. Unless consent to the terms of use or privacy policy is granted, the registration process cannot be completed. The data of the consent are stored until the basis for the storage lapses.

If you pay online by credit card, your data will be processed by our payment provider “iPayment” (, a branch of “1&1 Internet SE” ( Of course “iPayment/1&1” has the mandatory PCI certificate of the highest security level. The privacy policy of 1&1 can be found at

Quintessence Publishing has no access to your credit card number. We can only see the last 3 digits and get the information if the payment was successful or not.

What happens to your data?

Insofar as no statutory retention periods preclude this, the messages sent via the Website are deleted immediately after processing/answering or after the lapse of the basis for retention. In principle, the Website of Quintessenz Verlags-GmbH can be used without registration and identification, i.e. anonymously. The user him or herself decides whether to communicate data, which data to communicate, and generally indicates the purpose for which the data is communicated. Your data will only be used for the purpose for which you communicate them or for which they were collected (purpose limitation). You can object at any time to the use of your communicated data. For the settlement of orders, however, it is necessary to receive data for the processing. For this reason, no order is possible without adequate specification of your data.

Email and contact forms

The Website does not use contact forms. If you contact us by email, we will only use the personal data you provide to process your specific request. After the lapse of the purposes for the storage and processing of personal data, they will be erased by Quintessenz Verlags-GmbH without undue delay.

Processing of data outside the European Union

Processing of personal data outside the European Union will only take place to the extent that you order products from third-party providers of corresponding countries or if tools for analyzing data traffic to websites (e.g. Google Analytics or Google Tag Manager) are used, now or in the future. Regarding the use of analysis tools such as Google Analytics and the relevant rights to object, reference is made to the corresponding section of this Privacy Policy.
