Purpose and data minimizatio

Holzmann Medien is a medium-sized company with strong print and online brands and is one of the 50 largest business and specialist interest publishing companies in Germany. We collect and use your personal data exclusively in accordance with the provisions of the European Union's and the Federal Republic of Germany's Data Protection Acts. In the following, we inform you about the type, scope and purpose of the collection and use of personal data. Any processing for purposes other than those specified below will not take place. You can retrieve this information from this website at any time.

Data transmission and logging for system-internal and statistical purposes

For technical reasons, your Internet browser automatically transmits data to our web server when you access our website. This includes the date and time of access, URL of the referring website, the files accessed, amount of data sent, browser type and version, operating system and your IP address. This data is stored separately from other data that you enter when using our website. It is not possible for us to assign this data to a specific person. This data is evaluated for statistical purposes and then deleted.

Inventory data

If a contractual relationship (e.g. webshop) between yourself and us is to be established or changed, we collect and use your personal data if this is necessary for these purposes. Your personal data is stored in particular for registration/login, the shopping basket and the payment and billing functions.

By order of the responsible authorities, we may in individual cases provide information about this data (inventory data), insofar as this is necessary for the purposes of criminal prosecution, averting danger, fulfilling the statutory duties of the constitutional protection authorities or the Military Counter-Intelligence Service or enforcing intellectual property rights.

Order procedure using SSL

We use a secure ordering process using SSL encryption. In the case of a secure order, when you call up an SSL-protected process, you will usually be expressly informed that your computer is entering the SSL security mode. Additional information: The web browser you are using contains detailed explanations about security procedures and encryption under the help notes. Pay particular attention to the "s" in the URL (the Internet address you enter). This indicates that your order on the Internet is secure.

Usage data

We collect and use personal data about you to the extent necessary to enable or bill for the use of our website (usage data). This includes, in particular, characteristics for your identification and information at the beginning and end as well as the scope of use of our offer.

For the purposes of advertising, market research and the needs-based design of our Internet offering, we may use pseudonyms to create user profiles. You have the right to object to this use of your data. We may not merge the usage profiles with data about the bearer of the pseudonym.

Affected persons and data categories

Affected are customers, visitors of the website, suppliers and business partners, as well as employees. This includes name, first name, address, IP and payment data. However, only to the extent described under purpose and data minimization.

Legal basis

Legal basis for the storage, processing and passing on of your data is your consent (e.g. with newsletters), our justified interest in the analysis of the user behavior, in communication with prospective customers and in the improvement of our Internet appearance, whereby the balance of interests did not result in any restriction of your rights and freedoms (art. 6 I f) EU-DSGVO) or in case of a purchase the sales contract with you.

Deletion of data

If the purpose ceases to apply and there is no legal retention period, the corresponding personal data will be deleted. In principle, the data will only be stored for the duration of the above-mentioned purposes.

Recipients or categories of recipients to whom the data may be disclosed

Your data will be transferred to the sender for the purpose of order processing. In addition, data will be forwarded to the appropriate payment service during the payment process. In addition, the data is transmitted to webhosters, which we have commissioned to host various sites. We are also obliged to forward the data to the tax office or other authorities due to various legal regulations.

In addition, data will not be passed on to third parties without your explicit approval.

Data transfer to third countries

A data transfer to third countries does not take place.

This website uses cookies. Website cookies are small files that allow specific information related to the device to be stored on the user's access device (PC, smartphone, etc.). They serve the user-friendliness of websites and therefore the users (e.g. storage of login data). They also serve to collect statistical data on the use of the website and to be able to analyse them in order to improve the offer. Users can influence the use of cookies. Most browsers have an option that restricts or completely prevents the storage of cookies. However, it should be noted that the use and in particular the comfort of use are restricted without cookies.

Use of Google Ads conversion tracking

On our website we use the online advertising program Google Ads and in this context conversion tracking. Google Conversion Tracking is an analysis service provided by Google. When you click on an ad placed by Google, a conversion tracking cookie is placed on your computer. These cookies have a limited validity, do not contain any personal data and are therefore not used for personal identification. If you visit certain pages on our website and the cookie has not expired, Google and we may recognize that you clicked on the ad and were directed to that page. Because each Google Ads customer receives a different cookie, there is no way that cookies can be tracked through Ads customer websites.

The information collected through the conversion cookie is used to compile conversion statistics. We learn the total number of users who clicked on one of our ads and were directed to a page tagged with a conversion tracking tag. We do not receive or process any personally identifiable information in this context. The legal basis for the processing is Art. 6 para. 1 lit. f DSGVO, which is based on the legitimate interest in targeted advertising and the analysis of the effect and efficiency of this advertising, whereby the balancing of interests does not result in any impairment of the rights and freedoms of the user.

Your rights: You have the right at any time to object to this processing of your personal data based on Art. 6 para. 1 lit. f DSGVO. To do this, you can prevent the storage of cookies by selecting the appropriate technical settings in your browser. However, we would like to point out that in this case you may not be able to use all the functions of this website to their full extent. You will then not be included in the conversion tracking statistics. You can also deactivate personalized advertising for yourself in the Google advertising settings. You will find instructions on how to do this at . Further information and Google's data protection declaration can be found at:

Use of the "Scalable Central Measurement Method"

Our website uses the "Scalable Central Measurement Method" (SZM) of INFOnline GmbH ( to determine statistical parameters for the use of our offers. The aim of the usage measurement is to statistically determine the number of visits to our website, the number of website visitors and their surfing behaviour - on the basis of a uniform standard procedure - and thus to obtain market-wide comparable values. For all digital offers made by members of the Information Association for the Determination of the Distribution of Advertising Media, the following data is available (IVW, or to the studies of the working group for online research (AGOF, /), the usage statistics are regularly compiled by the AGOF and the Media Analysis Working Group (agma, and published with the performance value "Unique User" as well as by the IVW with the performance values "Page Impression" and "Visits". These ranges and statistics can be viewed on the respective websites.

The purpose of processing personal data is to create statistics and user categories. The statistics serve to trace and document the use of our offer. The user categories form the basis for an interest-oriented orientation of advertising media or advertising measures. In order to market this website, it is essential to measure its usage in order to ensure comparability with other market participants. Our justified interest results from the usability of the knowledge resulting from the statistics and user categories and the market value of our website - also in direct comparison with websites of third parties - which can be determined on the basis of the statistics.

Anonymous or anonymized measured values are collected. Before any processing, your IP address is shortened by 8 bits and further processed exclusively anonymously. A storage or further processing of unabridged IP addresses does not take place. The range processing uses a randomly generated client identifier for the recognition of computer systems. Alternatively, either a cookie with the identifier "", a "Local Storage Object" or a signature created from various automatically transmitted information of your browser is used. This identifier is unique for a browser as long as the cookie or local storage object is not deleted. A measurement of the data and subsequent assignment to the respective client identifier is therefore also possible if you call up other websites that also use the INFOnline GmbH measurement method ("SZMnG"). After one year, the cookie automatically becomes invalid without you having to do anything about it.

INFOnline GmbH's measurement method, which is used on this website, collects usage data. This is done in order to collect the performance values "page impressions", "visits" and "clients" and to form further key figures (e.g. qualified "clients"). In addition, the measured data is used as follows:

A so-called geolocalization, i.e. the allocation of a website call to the location of the call, takes place exclusively on the basis of the anonymous IP address and only up to the geographical level of the federal states/regions. In no case can the geographical information obtained in this way be used to draw conclusions about the specific whereabouts of a user.

The usage data of a technical "client" (e.g. a browser on a device) is merged across websites and stored in a database and transmitted to the AGOF service providers for the purpose of the AGOF study.

The shortened IP address is stored for a maximum of 60 days. The usage data in connection with the unique identifier is stored for a maximum of 6 months.

The IP address as well as the abbreviated IP address are not passed on. For the preparation of the AGOF study, data with client identifiers are passed on to the following AGOF service providers: Kantar Deutschland GmbH (, Ankordata GmbH & Co. KG ( and Interrogare GmbH (

If you do not wish to take part in the measurement, you can object by clicking on the following link: In order to guarantee an exclusion from the measurement, it is technically necessary to set an opt-out cookie. If you should delete the cookies in your browser, it is necessary to repeat the opt-out process under the above link.

You can find further information on data protection in the measurement process on the website of INFOnline GmbH (, which operates the measurement process, the data protection website of AGOF ( and the data protection website of IVW (
