5. Tracking technologies

We use cookies on our website. These are small files that are automatically created by your browser and stored on your end device (laptop, tablet, smartphone or similar) when you visit our site.

Information is stored in the cookie that is related to the specific end device used. However, this does not mean that we gain direct knowledge of your identity. The use of cookies serves, on the one hand, to make the use of our offer more pleasant for you. We use so-called session cookies to recognise that you have already visited individual pages of our website.

In addition, we also use temporary cookies to optimise user-friendliness, which are stored on your end device for a certain fixed period of time. If you visit our site again in order to use our services, it is automatically recognised that you have already been with us and which entries and settings you have made so that you do not have to enter them again. On the other hand, we use cookies to statistically record the use of our website and to evaluate it for the purpose of optimising our offer for you. These cookies enable us to automatically recognise that you have already been to our website when you visit it again.

The data processed by cookies is necessary for the above-mentioned purposes. Most browsers accept cookies automatically. However, you can configure your browser in such a way that no cookies are stored on your computer or a message always appears before a new cookie is created. However, the complete deactivation of cookies may mean that you cannot use all the functions of our website.


6. Web and newsletter analysis

In order to obtain information about the use of our website, to improve our Internet offering and to be able to address you with advertising on third-party websites or on social media, we use the following technologies: Google Analytics, Google Maps, Google Tag Manager, Google reCAPTCHA, Adobe Fonts, Social Media Plugins, Newsletter Tracking.

These tools are provided by third-party providers. As a rule, the information collected for this purpose about the use of a website is transmitted to the third-party provider's server through the use of cookies or similar technologies. Depending on the third-party provider, these servers may be located abroad.

The transmission of the data usually takes place with shortening of the IP addresses, which prevents the identification of individual end devices. A transmission of this information by third-party providers only takes place due to legal regulations or in the context of order data processing.


​​​​​​​6.1 Google Analytics

We use Google Analytics, the web analysis service of Google LLC, Mountain View, California, USA, on our websites. Google Limited Ireland ("Google") is responsible for Europe. To deactivate Google Analytics, Google provides a browser plug-in at Google Analytics uses cookies. These are small text files that make it possible to store specific information related to the user on the user's terminal device. These enable an analysis of the use of our website by Google. The information collected by the cookie about the use of our pages (including your IP address) is usually transmitted to a Google server in the USA and stored there. We would like to point out that on this website Google Analytics has been extended by the code "gat._anonymizeIp();" to ensure anonymised collection of IP addresses (so-called IP masking). If anonymisation is active, Google shortens IP addresses within member states of the European Union or in other contracting states of the Agreement on the European Economic Area, which is why no conclusions can be drawn about your identity. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. Google may associate your IP address with other Google data. For data transfers to the USA, Google has undertaken to sign and comply with the EU standard contractual clauses.


​​​​​​​​​​​​​​6.2 Google Maps

On our website we use Google Maps (API) from Google Inc. (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; responsible for Europe is Google Limited Ireland, "Google"). Google Maps is a web service for displaying interactive (land) maps in order to visually present geographical information. By using this service, our location is shown to you and a possible approach is made easier. When you call up those sub-pages in which the Google Maps map is integrated, information about your use of our website (such as your IP address) is transmitted to Google servers in the USA and stored there. This takes place regardless of whether Google provides a user account via which you are logged in or whether no user account exists. If you are logged in to Google, your data will be directly assigned to your account. If you do not wish your data to be associated with your Google profile, you must log out before activating the button. Google stores your data (even for users who are not logged in) as usage profiles and evaluates them.

For data transfers to the US, Google has committed to sign and comply with the EU standard contractual clauses.


​​​​​​​6.3 Google Tag Manager

We use Google Tag Manager on our website to create tags for our website and applications. These tags enable us to target marketing measures concerning our services to potential customers (re-targeting).

We use advertising technologies from Google (Ads) and Facebook. According to our settings in Google Tag Manager, Google and Facebook set so-called conversion cookies. This is necessary to verify the effectiveness of the corresponding advertising measures. We have a legitimate interest in this. In addition, we use Google Tag Manager to set re-targeting tags. These tags enable us to target users with information about our services when they visit another website (e.g. Facebook).


​​​​​​​6.4 Adobe Fonts

This website uses web fonts from Adobe for the uniform display of certain fonts. The provider is Adobe Systems Incorporated, 345 Park Avenue, San Jose, CA 95110-2704, USA (Adobe).

When you call up this website, your browser loads the required fonts directly from Adobe in order to be able to display them correctly on your end device. In doing so, your browser establishes a connection to Adobe's servers in the USA. This enables Adobe to know that your IP address has been used to access this website. According to Adobe, no cookies are stored when providing the fonts.

The storage and analysis of the data is based on Art. 6 para. 1 lit. f DSGVO. The website operator has a legitimate interest in the uniform presentation of the typeface on its website. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a DSGVO and § 25 para. 1 TTDSG, insofar as the consent includes the storage of cookies or access to information in the user's terminal device (e.g. device fingerprinting) as defined by the TTDSG. The consent can be revoked at any time.

Data transfer to the USA is based on the standard contractual clauses of the EU Commission.


​​​​​​​6.5 Social Media Plugins

So-called social media plugins ("plugins") from third-party providers are used on our website. The plugins are recognisable by the logo of the respective social network. Via the plugins, we offer you the opportunity to interact with the social networks and other users. We use the following plugins on our website: Facebook, Instagram, LinkedIn, YouTube. When you call up our website, your browser establishes a direct connection to the servers of the third-party provider. The content of the plugin (e.g. YouTube videos) is transmitted directly to your browser by the respective third-party provider and integrated into the page.

The data transfer for the display of content (e.g. publications on Instagram) takes place regardless of whether you have an account with the third-party provider and are logged in there. If you are logged in to the third-party provider, the data we collect is also directly assigned to your account with the third-party provider. If you activate the plugins, the information will also be published on the social network and displayed to your contacts there. The purpose and scope of the data collection and the further processing and use of the data by the third-party providers, as well as your rights in this regard and setting options for protecting your privacy, can be found in the data protection information of the third-party providers. The third-party provider stores the data collected about you as a usage profile and uses it for the purposes of advertising, market research and/or designing its website to meet your needs. Such an evaluation is also carried out in particular for users who are not logged in for the purpose of displaying needs-based advertising and to inform other users of the social network about your activities on our website. If you would like to prevent the third-party providers from assigning the data collected via our website to your personal profile in the respective social network, you must log out of the corresponding social network before visiting our website. You can also completely prevent the loading of the plugins with specialised add-ons for your browser such as "Ghostery" or "NoScript".


​​​​​​​6.6 Newsletter Tracking

We use Hubspot to send our digital newsletters. With this software, newsletters can be sent and analysed. In order to carry out this analysis, we collect device and access data. To collect these, the newsletter contains a pixel. The newsletter and the websites that can be accessed from this newsletter are also tracked with cookies. A pixel is an image file that is stored on the recipient's device.

With the help of these technologies, we receive information as to whether the newsletter has been received, opened and which content has been clicked on. We use this information to improve our newsletter and our offers.  The setting of a pixel can be prevented by deactivating HTML in the mail programme (this varies depending on the mail programme). 


7. Data Sharing and Data Transfer

We will only disclose your data to third parties if this is necessary to provide our service, if these third parties provide a service for us, if we are obliged to do so by law or by the authorities or if we have an overriding interest in disclosing the personal data. We will also disclose personal data to third parties if you have given your consent or requested us to do so.

Not all personal data is transmitted in encrypted form as standard. Unless explicitly agreed otherwise with the client, all data is transmitted unencrypted.

The following categories of recipients may receive personal data from us:

  • Other service providers (e.g. IT service providers, hosting providers, suppliers).
  • Third parties within the scope of our legal or contractual obligations, authorities, state institutions, courts.

We conclude contracts with service providers who process personal data on our behalf, obliging them to ensure data protection. The majority of our service providers are located in Switzerland or in the EU / EEA. Certain personal data may also be transferred to the USA (e.g. Google Analytics data) or, in exceptional cases, to other countries worldwide. If data transfer to other countries that do not have an adequate level of data protection is necessary, this will be done on the basis of the EU standard contractual clauses (e.g. in the case of Google) or other suitable instruments.


8. Duration of storage of personal data

We process and store your personal data for as long as it is necessary for the fulfillment of our contractual and legal obligations or for the other purposes pursued with the processing, i.e. for example for the duration of the entire business relationship (from the initiation, processing to the termination of a contract) as well as in accordance with the statutory retention and documentation obligations. It is possible that personal data will be stored for the period in which claims can be asserted against our company (i.e. in particular during the statutory limitation period) and insofar as we are otherwise legally obliged to do so or legitimate business interests require this (e.g. for evidence and documentation purposes). As soon as your personal data are no longer required for the above purposes, they will be deleted or made anonymous as far as possible. In principle, shorter retention periods of twelve months or less apply to operational data (e.g. system protocols, logs).


9. Data Security

We take appropriate technical and organizational security precautions to protect your personal data

  • against unauthorized access (confidentiality)
  • so that they are available when they are needed (availability)
  • against misuse and changes (integrity)
  • so that they are processed in a traceable manner (traceability).

This can be done by issuing instructions, training, IT and network security solutions, access controls and restrictions, encryption of data carriers and transmissions, pseudonymization and controls.

The data protection officer of Trafo Baden Betriebs AG must be involved in new projects from the start and regularly checks data security in accordance with the principles, goals and TOMs in Art. 1 to 3 DSV.


10. Obligation to provide personal data

As part of our business relationship, you must provide the personal data that is required to establish and conduct a business relationship and to fulfill the associated contractual obligations (as a rule, you do not have a legal obligation to provide us with data). Without this data we will not be able to enter into a contract with you (or the entity or person you represent) or to perform it. The website cannot be used either if certain information to ensure data traffic (e.g. IP address) is not disclosed.
