4.4.3 Google Analytics

We use Google Analytics on our website. This is a web analysis service owned by Google Ireland Limited, Gordon House, 4 Barrow St, Dublin, D04 E5W5, Irland (Google). Google uses cookies (see 4.4.2 above). The information generated by the cookie concerning the customer’s use of the website is generally transmitted to a Google server in the USA and processed there. The same applies for your anonymous IP address. Furthermore, Google Analytics processes the data held in the log files, the address of the website which you accessed before you came to our website (Referrer URL) and the search term and search engine through which you found our website.

Google will process this data on our behalf in order to evaluate customer use of our website and to compile reports about website activities. Google uses the data held in the log files for example to compile statistics on how frequently our website is accessed or for the generation of sales figures. In doing so, pseudonymous user profiles of visitors to the website can be created from processed data.

We only use Google Analytics with activated IP anonymization. This means that your IP address gets truncated by Google within the member states of the European Union or European Economic Area. Only in exceptional circumstances will the full IP address be transmitted to a Google server in the USA and truncated there.

4.4.4 The use of Google AdWords Conversion tracking

We use Google AdWords in order to draw attention to our products and special offers with the help of advertising on external websites. This allows us to determine how successful the individual advertising measures are.

This kind of advertising material is delivered by Google using so-called “Ad Servers”. Here we use Ad Server cookies which allow specific parameters for measuring success, such as the number of pop- ups or how many clicks the advertisement had. If you get on to our website via a Google ad then Google AdWords will save a cookie on your computer or device. Validity of marketing cookies (see 4.4.2). Data used for analysis purposes is usually saved from this cookie (cookie ID, the number of Ad Impressions per positioning (frequency), last Impression as well as opt-out information, which serves as an indicator that the user does not want to receive customized advertising.

These cookies allow Google to recognize your browser. If a user visits specific internet pages of an AdWords’ customer and the cookie saved on the computer or device has not yet expired, both Google and the AdWords customer can see that the user has clicked on the advertisement and was redirected to this page. Every AdWords customer is assigned a different cookie; cookies cannot be traced back via the internet pages of the AdWords customer. We ourselves do not process any data with regards to these advertising measures. We simply receive statistical evaluations from Google. These evaluations allow us to identify which marketing measures are effective.

Because of the marketing tools used, your browser automatically forms a direct connection with the Google server. We have no influence over the further processing of data by Google. Due to the integration of AdWords Conversion, Google gets the information that you have accessed a certain part of our website or that you have clicked on one of our advertisements. If you are registered on any Google services, Google can allocate this browsing to your account. Even if you are not registered to Google or are not logged in at the time, there is still a possibility that the provider is processing your IP address.

The legal basis for this is Article 6, Paragraph 1f) of the DSGVO and if you have given your consent Article 6, Paragraph 2a) of the DSGVO. We are pursuing our interest in providing you with relevant advertising whilst at the same time keeping our advertising costs to a fair level.

The disclosure of data to Google is not obligatory or necessary to enter into a contract with us.

You have the possibility at any time to change the cookie settings in the cookie banner on klett-international or to give or revoke consent at a later date (see 4.4.2).
