Privacy Policy

1. Person in charge and data protection officer

This Privacy Policy is applicable to users within both the European Union and Switzerland. It is created in compliance with relevant data protection regulations, including the General Data Protection Regulation (GDPR) of the EU and the revised Data Protection Act (revDSG) of Switzerland.

The entity responsible for the collection and processing of your personal data on this website is:

W4 Marketing AG
Idastrasse 14
8003 Zürich

Our data protection officer is David Köhler.

You may contact our data protection officers via: dkohler(at)

Any data subject that has questions and/or suggestions may contact our data protection officers at any time. 

2. personal data and its use

2.1 How do we manage personal data?

Data protection has a particularly high priority in our company. We treat your personal data confidentially and in accordance with the statutory data protection regulations and this privacy policy.
The use of our internet pages is in principle possible without entering any personal data. However, if an affected person wishes to use certain services (such as contact forms, newsletter registration) on our website, personal data processing may be required.
If the processing of personal data is required and there is no legal basis for such processing, e.g. the fulfillment of a contract or fulfillment of a legal obligation, we generally obtain the consent of the data subject. In addition, personal data processing will always be in accordance with the General Data Protection Regulation (hereafter GDPR) and in accordance with country-specific privacy policies.

Data we process on our Website

We process personal data that we obtain in the course of your use of our services. The processed data includes, in particular:

  • Identification data (e.g., name, email address)
  • Contact data (e.g., phone number, address)
  • Usage data (e.g., visited websites, interest in content, access times)
  • Meta and communication data (e.g., device information, IP addresses)

This data is processed exclusively for the purposes stated in this privacy policy. We strictly adhere to the principles of data minimization and data avoidance.

2.2 Purpose of the Privacy Policy 

By means of this privacy policy we would like to inform our website visitors about the nature, extent and purpose of the personal data collected, used and processed by us. Furthermore, we would like to inform you about your rights. 

2.3 Technical and organizational measures

As data controller, we have implemented numerous technical and organizational measures to ensure the most complete protection possible for personal data processed via this website. Our websites as well as our blog have included an SSL certificate to increase security. The SSL certificate is used to encrypt the data exchanged over HTTP. Nevertheless, Internet-based data transmissions can in principle have security gaps so that absolute protection cannot be guaranteed.

2.4 Legal Basis

Insofar as we obtain your consent for processing personal data, Art. 6 para. 1 lit. a) EU General Data Protection Regulation (GDPR) serves as the legal basis for processing.

If the processing of personal data is necessary to fulfill a contract with you, as is the case, for example, with processing operations necessary for the supply of goods or the provision of any other service or consideration, the processing is based on Article 6 (1) lit. b GDPR. The same applies to processing operations that are necessary to carry out pre-contractual measures, for example in cases of inquiries regarding our products or services.

If we are subject to a legal obligation which requires the processing of personal data, such as the fulfillment of tax obligations, the processing is based on Art. 6 para. 1 lit. c GDPR.

In rare cases, the processing of personal data may be required to protect vital interests of you or another natural person. This would be the case if, for example, a visitor to our company were injured and his / her name, age, health insurance or other vital information would have to be passed on to a doctor, hospital or another third party. In this case, data processing would be based on Art. 6 para. 1 lit. d GDPR.

2.5 Storage and Deletion

Your personal data will be deleted or inactivated as soon as the purpose of the storage has been completed. However, data may be stored beyond that if European or national legislatures in their laws or regulations to which we as a company are subject provide for such data storage.


We use the marketing automation software HubSpot of the American company Hubspot Inc., 2nd Floor 30 North Wall Quay, Dublin 1, Ireland, hereafter "Hubspot", for the realization of our website and our blog.

Our website uses Google Analytics. This is a service of Google Inc. ("Google") for the analysis of accesses to Internet pages and enables us to improve our Internet offers. Cookies (see above) enable us to analyze your use of our website. The information collected by means of a cookie (IP address, access time, access duration) is transmitted to a Google server in the USA and stored there. The evaluation of your activities on our website will be transmitted to us in the form of reports. Google may disclose the collected information to third parties where required to do so by law or where such third parties process the information on Google's behalf. The Google tracking codes of our Internet offer use the function "_anonymizeIp()", thus IP addresses are only processed further in abbreviated form in order to exclude any possible direct personal reference to you. You can also prevent the installation of cookies by Google Analytics by choosing the corresponding setting in your browser software.

6. Use of Google maps

We use the component "Google Maps" from Google Inc. 1600 Amphitheatre Parkway, Mountain View, CA 94043 USA, hereafter "Google", on our website.
Each time you access the Google Maps component, Google sets a cookie to process user settings and data when you view the page that includes the Google Maps component. As a rule, this cookie is not deleted when you close your browser, but expires after a certain period of time, unless you delete it manually beforehand.
If you do not agree to this processing of your data, it is possible to deactivate the "Google Maps" service and thus prevent the transfer of data to Google. To do this, you must deactivate the Java Script function in your browser. However, we would like to point out that in this case you will not be able to use "Google Maps" or only to a limited extent. The use of "Google Maps" and the information obtained via "Google Maps" is subject to Google's Terms of Use as well as the additional terms and conditions for "Google Maps".


Our website links to our Facebook page as well as to our profiles on Twitter, Google+, LinkedIn and Xing. No data will be transmitted to Facebook, Twitter, Google+, LinkedIn or Xing simply by linking to the respective pages via the icons.

We point out that you use our Facebook, Twitter, Google+, LinkedIn and Xing pages as well as their functions voluntarily and on your own responsibility. This is especially true for the use of interactive features (e.g., commenting, sharing, rating). We point out that the data collected about you in this context are processed by Facebook Ltd., Twitter Inc., Google LLC, LinkedIn Inc. and Xing SE, and may be transferred to countries outside the European Union. The data that Facebook, Twitter, Google, LinkedIn, or Xing receives and how they are used is described in the general terms and conditions by the respective providers in their data usage policies. You will also find information about contact options as well as the setting options for advertisements there. You can view the data usage guidelines here:


Our site uses YouTube LLC, 901 Cherry Avenue, San Bruno, CA 94066, USA, represented by Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA, for embedding videos. Usually, when you visit an embedded video page, your IP address will be sent to YouTube and cookies will be installed on your device.

However, we embed our YouTube videos with the enhanced privacy mode. In this case, YouTube will still contact the Google DoubleClick service, but Google's privacy policy will not evaluate your personal information. As a result, YouTube does not store any information about visitors unless they watch the video. If you click the video, your IP address will be sent to YouTube, and YouTube will know that you have watched the video. If you are logged in to YouTube, this information will also be assigned to your user account. You can prevent this by logging out of YouTube before starting the video.

We have no knowledge of and no influence on the possible collection and use of your data by YouTube. For more information, see YouTube's privacy policy. In addition, for the general handling and deactivation of cookies, please refer to our general description in this data protection declaration.



Some of our internet offers contain hyperlinks to other websites which are not operated by us. We do not monitor these websites and are neither responsible for their content nor their handling of personal data.



The hosting service provider of our web pages automatically collects and saves information in so-called server log files, which your browser automatically sends to us, whenever our web pages are accessed. These include:

  • Visited website
  • Date and time of website visit / server request
  • Transferred amount of data
  • Message about successful retrieval
  • Browser type and browser version
  • Used operating system
  • Referrer URL (the previously visited page)
  • Host name of the accessing computer
  • IP addresses

The temporary storage of the IP address by the system is necessary to allow delivery of our web pages to your computer. For this, the IP address must be stored for at least the duration of the session. In addition, the data in the log files serve to optimize our websites and to ensure the security of our websites. Logfiles are not used to evaluate the behavior of website visitors and for marketing purposes and are not associated with other data collected by us. The storage of IP addresses enables law enforcement in the case of cyberattacks or in case of illegal use, because the IP addresses can be assigned to a user through the provider so that they can be identified. For this reason, the log files are stored at our hosting partner for a period of 6 months and then deleted.
The legal basis for the storage of the data in the log files is Article 6 (1) (f) GDPR. The collection of the data for the provision of the web pages and the storage of the data in log files is essential for the operation of our website. There is consequently no possibility of contradiction by you.
