What kind of data is collected and how is it used?

1.1 Data collection by this website

Whenever a user accesses the website, the user’s internet browser automatically transfers the following data to Merck’s web server for technical reasons:

  • IP address of the requesting computer
  • date and time of access

This data is collected, processed and used for the purpose of enabling the use of the website (connection setup), system security and technical administration of the network infrastructure. A comparison with other databases or a transfer to third parties, also in excerpts, does not take place. The legal basis for processing is Art. 6 para. 1 b GDPR.

The data collected as part of the voluntary entries under “Contact us” will be used and processed exclusively for the purpose of processing the enquiry and to carry out the services you may have requested.

1.2 Use of Google Analytics

This website uses Google Analytics, a web analytics service provided by Google Inc. (“Google”). Google Analytics uses “cookies”, which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there. However, if you activate the IP anonymization on this website, your IP address will be shortened previously by Google within Member States of the European Union or in other contracting states of the Agreement on the European Economic Area. Only in exceptional cases the full IP address is transferred to a Google server in the USA and shortened there. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide the website operator with further services related to website and internet use. The IP address transmitted by your browser within the scope of Google Analytics will not be aggregated with other Google data. You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website. You can also prevent Google from collecting the data generated by the cookie and relating to your use of the website (including your IP address) and from processing this data by downloading and installing the browser plug-in available under the following link You can prevent Google Analytics from collecting data by clicking on the following link. An opt-out cookie is set that prevents future collection of your data when you visit this website: Deactivate Google Analytics.

For more information on terms of use and privacy, please visit or Please note that on the website Google Analytics has been extended by the code “anonymizeIp” in order to guarantee an anonymous registration of IP addresses (so-called IP masking).

The legal basis for processing is Art. 6 para. 1 f GDPR, whereby Merck’s authorization arises from the fact that, on the one hand, Merck has an interest in evaluating the website data for purposes of website optimization and, on the other hand, a concerned person can reasonably foresee at the time when the personal data is collected and in view of the circumstances under which it is carried out (in particular the above-mentioned measures) that it will possibly be processed for this purpose.

The legal basis for processing is Art. 6 para. 1 f GDPR, whereby Merck’s authorization arises from the fact that, on the one hand, Merck has an interest in evaluating the website data for purposes of website optimization and, on the other hand, a concerned person can reasonably foresee at the time when the personal data is collected and in view of the circumstances under which it is carried out (in particular the above-mentioned measures) that it will possibly be processed for this purpose.


Social media plugins

We use social media plugins from various social networks (e. g. Facebook). With the help of these plugins you can share content or recommend products. The plugins are deactivated by default and therefore do not send data to other websites. By clicking on the button “Activate Social Media” you can activate all plugins (so-called 2-click solution). The plugins can of course be deactivated again with one click.

If these plugins are activated, your browser establishes a direct connection with the servers of the respective social media network as soon as you access the operator’s website. The content of the respective plugin is transmitted directly from the social media network to your browser and embedded into the website.

By embedding the plugins, the social media network receives the information that you have visited the respective page of the operator. If you are logged in to the social media network, it can allocate the visit to your account. When you interact with the plugins, the corresponding information is transferred directly from your browser to the social media network and stored there.

For the purpose and scope of data collection and the further processing and use of the data by social media networks, as well as your rights and options for the protection of your privacy, please refer to the data protection notices of the respective networks.

If you do not want social media networks to collect information about you through the operator’s website, you must log out or disable the social media plugins before you visit our website.

Even if you are not logged in to social media networks, websites with active social media plugins can still send data to these networks. With an active plugin, a cookie with an identifier is placed each time the website is accessed. Since your browser sends this cookie every time you connect to a network server without being asked, the network could basically use it to create a profile of the websites visited by the user associated with the ID. And it would then also be possible to assign this identifier to a person again at a later time – for example when logging on later to the social network.

The operator uses the following plugins:


Is other personal data collected and processed?

We collect and process your personal data only if you request certain services and we need your data for this purpose or if you have voluntarily given us your express consent. The legal basis for processing is Art. 6 Para. 1 b GDPR and Art. 6 Para. 1 a GDPR.

You can do this, for example, by completing a registration form or sending us an email, ordering products or services, submitting inquiries to us, requesting materials or registering. Unless otherwise required by law, we will only use your personal data for the purposes for which you have given your consent.

At Merck KGaA, Darmstadt Germany, those bodies within Merck receive your data that are required to fulfill our contractual and legal obligations. Some data must be disclosed under strict contractual and legal requirements:

Due to legal obligation:
In certain cases, we are required by law to transfer data to a requesting public authority.

Upon submission of a court order, we are obliged pursuant to § 101 of the German Copyright Act to provide owners of copyright and ancillary copyrights with information about customers who are alleged to have offered copyright-protected works on internet file-sharing sites. In these cases, our information contains the user ID of an IP address allocated at the time requested and, if known, the name and address of the customer.

In other respects, personal data will only be transferred to state institutions and public authorities within the framework of mandatory national legal provisions or if disclosure is necessary in the event of attacks on the network infrastructure for legal or criminal prosecution. The legal basis for processing is Art. 6 Para. 1 c GDPR or § 24 Para. 2 No. 1 German Federal Data Protection Act.

To external service providers for data processing:
When service providers get access to our customers’ personal data, this usually takes place in the course of so-called order processing of personal data. This is expressly provided for by law. In this case, Merck remains responsible for the protection of your data – in addition, the processor may also be responsible. The service provider works strictly in accordance with our instructions, which we ensure by means of strict contractual regulations, technical and organizational measures and supplementary controls.

Merck works with service suppliers as processors. These are Merck Group companies and service providers for IT services (e. g. for technical-administrative tasks and for usage analysis), telecommunications, consulting and advisory services as well as sales and marketing.

The data protection regulations for instruction-bound order processing of personal data are complied with.

To Merck Group companies:
Merck may transfer your personal data to Merck Group companies in order to carry out a business relationship with you or for the purposes of legitimate interests.

If data are transferred abroad, they are based within the EU or the EEA or in a country which, according to the decision of the EU Commission, has an appropriate level of data protection. In the case of data transfers to Merck Group companies domiciled in other countries, Merck ensures by way of guarantees that the data-importing Merck Group company has been obligated to an appropriate level of data protection.

Beyond this, we do not transfer data to third parties unless you have given your express consent, the transfer is obviously necessary for the provision of an offer or service requested by you or this is provided for by law. We also do not intend to transfer your data beyond this to a third country or international organization.
