The processing here includes all data processed within the framework of the relationship between Fronius and the data subject, if this is necessary to achieve the purpose. The legitimate interest of Fronius or its group companies and of recipients of communications is also to be capable of operating a group-wide customer and supplier management system for the purpose of administrative optimization and simplification.

The information generated by the cookie about your use of this website is usually transmitted to a Google server in the USA and stored there. However, if IP anonymisation is enabled on this website, your IP address will first be truncated by Google within the member states of the European Union or other states party to the agreement on the European Economic Area. Only in exceptional cases will the full IP address be transferred to a Google server in the USA and truncated there. On behalf of the operator of this website, Google will use this information to evaluate your use of the website in order to compile reports about the website activity for us as website operators and to provide other services associated with the use of the website. The IP address that your browser transmits within the scope of Google Analytics will not be associated with any other data held by Google.

The provider is Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.This function enables the advertising target groups created with Google Analytics Remarketing to be linked with the cross-device functions of Google AdWords and Google DoubleClick. This allows advertising messages to be displayed based on your personal interests, identified from your previous usage and surfing behaviour on one device (e.g. your mobile phone), on other devices (such as a tablet or computer). 

10.2 Once you have given your consent, Google will associate your web and app browsing history with your Google Account for this purpose. That way, any device that signs in to your Google Account can use the same personalised advertising messages.

You can permanently object to cross-device remarketing/targeting by deactivating personalized advertising in your Google account; follow this link:

10.4 The summary of the data collected in your Google Account is based solely on your consent, which you can submit or revoke to Google (Art. 6 par. 1 lit. a, GDPR). For data collection operations that are not merged into your Google Account (for example, because you do not have a Google Account or have op-posed the merge), the collection of data is based on Article 6, para. 1, lit f of the GDPR. The legitimate interest arises from the fact that the website operator has an interest in anonymous analysis of website visitors for advertising purposes.
