Access data (server log files)

When you access our website, we automatically collect and store access data in so-called server log files, which your browser automatically transmits to us. These are:

As a rule, it is neither possible nor intended for us to make personal references. Such data is processed in accordance with Article 6 (1) (f) GDPR to protect our legitimate interest in improving the stability and functionality of our website.

Cookies

In order to make visiting our website attractive and to enable the use of certain functions, we use so-called cookies. These are small text files that are stored on your device. Cookies cannot run programs or transmit viruses to your computer system.

Cookies that are necessary to carry out the electronic communication process or to provide certain functions you require are stored on the basis of Art. 6 Para. 1 lit. f GDPR. We have a legitimate interest in storing cookies in order to provide our services in a technically error-free and optimized manner. If other cookies (e.g. cookies to analyze your surfing behavior) are stored, they will be treated separately in this data protection declaration.

Most of the cookies we use are so-called “session cookies”. They will be automatically deleted at the end of your visit. Other cookies remain stored on your device until you delete them. These cookies enable us to recognize your browser the next time you visit.

You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when you close the browser. If cookies are deactivated, the functionality of this website may be restricted.

Web analysis tools and advertising

Google Analytics

Our website uses the web analysis service Google Analytics in version Google Analytics 4. The provider is Google Ireland Ltd., Gordon House, Barrow Street, Dublin 4, Ireland (“Google”).

Google Analytics uses so-called “cookies”. These are text files that are stored on your computer and enable your use of our website to be analyzed. In Google Analytics, all data from devices located in the EU (based on geographical location according to IP address) is collected via domains and servers in the EU before the traffic is forwarded to Analytics servers for processing.

The legal basis for the processing of your data is the consent you gave via the cookie consent tool in accordance with Article 6 Paragraph 1 Sentence 1 Letter a) GDPR.

IP anonymization

With Google Analytics, the IP anonymization function is automatically activated on the website. This means that your IP address will be shortened by Google within EU member states or in other contracting states to the Agreement on the European Economic Area before it is transmitted to the USA. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. On our behalf, Google will use this information to evaluate your use of our website, to compile reports on website activity and to provide us with other services relating to website activity and internet usage. According to Google, no IP addresses are logged and stored in Google Analytics, but are only briefly processed for geo-location and then deleted immediately. The IP address transmitted by your browser as part of Google Analytics is not combined with other Google data.

Demographic characteristics in Google Analytics

Our website uses the “demographic characteristics” function of Google Analytics. This allows reports to be created that contain information about the age, gender and interests of site visitors. This data comes from interest-based advertising from Google and third-party visitor data. This data cannot be assigned to a specific person. You can deactivate this function at any time via the ad settings in your Google account or generally prohibit the collection of your data by Google Analytics - as shown in the section “Objection to data collection”.

Google Signals

In connection with this website, the Google Signals service is also used as an extension of Google Analytics. With Google Signals we can have Google create cross-device reports (so-called “cross device tracking”). If you have activated “personalized ads” in your settings in your Google account and linked your internet-enabled devices to your Google account, Google can analyze usage behavior across devices when you give your consent to the use of Google Analytics in accordance with Art. 6 Para. 1 lit. a GDPR and create database models based on this. The logins and device types of all website users who were logged into a Google account and carried out a conversion are taken into account. The data shows, among other things, on which device you clicked on an ad for the first time and on which device the corresponding conversion took place. We do not receive any personal data from Google, but only statistics created on the basis of Google Signals. You have the option to deactivate the “personalized ads” function in the settings of your Google account and thus turn off cross-device analysis in connection with Google Signals. To do this, follow the instructions on this page: https://support.google.com/ads/answer/2662922?hl=de. Further information about Google Signals can be found at the following link: https://support.google.com/analytics/answer/7532985?hl=de.

Order processing

We have concluded an order processing contract with Google and fully implement the strict requirements of the German data protection authorities when using Google Analytics.

Storage period

User and event-level data stored by Google that is linked to cookies, user identifiers (e.g. User ID) or advertising IDs (e.g. DoubleClick cookies, Android advertising ID) will be deleted after 14 months. Details can be found at the following link: https://support.google.com/analytics/answer/7667196?hl=de.

Right of withdrawal

Many data processing operations are only possible with your express consent. If the processing of your data is based on your consent, you have the right to revoke your consent to the processing of data in accordance with Art. 7 Para. 3 GDPR at any time with effect for the future by accessing the cookie settings and changing your selection there. The revocation of consent does not affect the lawfulness of the processing carried out based on the consent before its revocation. Storage of data for billing and accounting purposes remains unaffected by a revocation.

You can find more information about how Google Analytics handles user data in Google's privacy policy: https://support.google.com/analytics/answer/6004245?hl=de.

Further information on data protection can be found in Google's privacy policy: https://policies.google.com/privacy?hl=de&gl=de

Google Tag Manager

Our website uses Google Tag Manager. The provider is Google Ireland Ltd., Gordon House, Barrow Street, Dublin 4, Ireland (“Google”). Google Tag Manager is a solution that allows marketers to manage website tags from one interface. The tool that implements the tags is a cookie-less domain and does not store any personal data. The tool triggers other tags, which in turn may collect data. Google Tag Manager does not access this data. If a deactivation has been made at the domain or cookie level, this will remain in effect for all tracking tags implemented with Google Tag Manager.

Google Ads and Google Conversion Tracking

Our website uses Google Ads (formerly Google AdWords). Google Ads is an online advertising program from Google.

Google Ads enables us to use advertising materials on external websites to draw attention to our offers and to determine how successful individual advertising measures are. This helps us to show you advertising that is of interest to you, to make our website more interesting for you and to achieve a fair calculation of advertising costs.

As part of Google Ads, we use so-called conversion tracking. The advertising materials are delivered by Google via so-called “AdServers”. For this purpose, we use so-called ad server cookies, through which certain parameters can be measured to measure success, such as display of ads or clicks by users. If you click on an ad placed by Google, a cookie is set for conversion tracking. Cookies are small text files that the Internet browser stores on the user's computer. These cookies expire after 30 days and are not used to personally identify users. These cookies enable Google to recognize your web browser. If you visit certain pages of our website if the cookie has not yet expired, Google and we can recognize that you clicked on the specific ad and were redirected to this page.

Each Google Ads customer receives a different cookie. The cookies cannot therefore be tracked via the websites of Ads customers. The following information is usually stored for the cookie as analysis values: unique cookie ID, number of ad impressions per placement (frequency), last impression (relevant for post-view conversions), opt-out information (marking that the user no longer wants to be addressed). The information collected using the conversion cookie is used to create conversion statistics for Ads customers who have opted for conversion tracking. Ads customers learn the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag. However, you will not receive any information that can be used to personally identify users. If you do not want to participate in tracking, you can object to this use by easily deactivating the Google Conversion Tracking cookie via your Internet browser under user settings. You will then not be included in the conversion tracking statistics.

The summary of the data collected in your Google account is based solely on your consent, which you can give or revoke at Google (Art. 6 Para. 1 lit. a GDPR). For data collection processes that are not merged in your Google account (e.g. because you do not have a Google account or have objected to the merger), the collection of data is based on Art. 6 Para. 1 lit. f GDPR. The legitimate interest arises from the fact that we have an interest in the anonymized analysis of visitors to our website for advertising purposes in order to optimize both our website and our advertising.

Further information and the data protection regulations can be found in Google's data protection declaration at: https://policies.google.com/technologies/ads?hl=de.

Google Fonts

We use “Google Fonts” (formerly “Google Web Fonts”), a service provided by Google, on our website.

Google Fonts allows us to use external fonts, so-called Google Fonts. When you access our website, the required Google Font is loaded into the browser cache by your web browser. This is necessary so that your browser can display a visually improved representation of our texts. If your browser does not support this function, your computer will use a standard font for display.

The integration of Google Fonts occurs through a server call, usually at a Google server in the USA. This sends information to the server about which of our websites you have visited. The IP address of your device's browser is also stored by Google. We have no influence on the scope and further use of the data collected and processed by Google through the use of Google Fonts.

We use Google Fonts for optimization purposes, in particular to improve your use of our website and to make its design more user-friendly. This is our legitimate interest in the processing of the above data by the third party provider. The legal basis is Article 6 Paragraph 1 Sentence 1 Letter f GDPR.

Further information about Google Fonts can be found at https://fonts.google.com/, https://developers.google.com/fonts/faq?hl=de-DE&csw=1.
