6. Pseudonymous user profiles
- Various cookies are used on our websites. In some cases, these are technically necessary in order to be able to offer our services at all. The legal basis for this is § 25 para. 2 TTDSG.
- We also use other cookies and tracking tools, which may also come from third-party providers. In addition to analysis purposes, these serve to increase the user's comfort, to carry out a range measurement and to constantly improve our offer. In addition, they can be used to display advertising tailored to the interests of the individual user. The legal basis for this is the consent voluntarily given by the user in accordance with § 25 para. 1 TTDSG, Art. 6 para. 1 sentence 1 lit. a) DSGVO.
The following paragraphs list the third-party providers who can access the data collected via their respective cookie or tracking tool. As far as indicated, data is transferred to countries outside of Germany and also to third countries outside of the European Union. Due to the location of individual third party providers, it is to be expected that data will also be transferred to the USA. The legal basis for this data transfer is also the consent voluntarily given by the user.
We would like to point out that the third countries outside the European Union may not offer an adequate level of data protection based on the decision of the European Commission. In this respect, it cannot be guaranteed that state or private institutions in the third country will not access the transmitted data and use it for purposes that would not be permissible under the provisions of the GDPR. This may include the creation or enrichment of profiles of the user for analysis purposes or for the purpose of sending target group-oriented advertising. In this respect, no suitable guarantees can be given for the protection of the data.

This website uses functions of the "Google Campaign Manager" service, in particular the "Floodlight" function. The service provider is Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. Campaign Manager is used to display interest-based advertisements to you throughout the Google advertising network. The ads can be targeted to the interests of the respective viewer with the help of Campaign Manager. For example, our ads may be displayed in Google search results or in banner ads on third party websites associated with Campaign Manager. In order to display ads to users that are tailored to their interests, Campaign Manager must be able to recognize the respective viewer. For this purpose, a cookie is stored in the user's browser, behind which the websites visited by the user, clicks and various other information is stored. This information is combined into a pseudonymous user profile in order to display interest-based advertising to the user in question. In the process, data is transferred to Google. Insofar as personal data is transferred to the USA, the appropriate safeguards for the transfer to a third country are the standard data protection clauses; more detailed information can be found at https://privacy.google.com/businesses/processorterms/.
Floodlight is a so-called conversion tracking system that can be used to measure the effectiveness of advertising measures. With the help of a cookie, we can determine whether you perform certain actions on our website after clicking on one of our ads on Google or on third-party websites.
The storage of cookies and the processing of personal data are based on your consent pursuant to Art. 6 (1) p. 1 lit. a) GDPR. Consent is voluntary and you can revoke it at any time with effect for the future. You can also deactivate personalized advertising using Google's "Advertising settings".

As a result, Facebook receives information from your browser including the fact that your terminal has accessed our website. If you are a Facebook user, Facebook can assign the visit to our websites to your user account. We would like to point out that we, as the providers of the websites, have no knowledge of the content of the transmitted data or of how it is used by Facebook. We can only select which sectors of Facebook users (such as age, interests) should see our advertisements displayed. In this process, we use one of two modes of working from Custom Audiences, in which no datasets — in particular, none of our users’ e-mail addresses — are transferred to Facebook.

- Google Analytics with Conversion Tracking and Google Signals
We use Google Analytics, a Web analysis service from Google Inc. (“Google”), including the functions “Conversion Tracking" and Google Signals. Google Analytics employs so-called “cookies”, which are text files that are stored on your terminal and make it possible to analyse how you are using the website, the products that you view and possible purchases that you make. No personal data are collected during this process. The information created by the cookie (including your abbreviated IP address) is transferred to a Google server in the USA and stored there. Google will use this information to evaluate it, to create reports on the website activities and the products viewed or sold for the operators of the website, and to provide additional services connected with the use of the website and the Internet. If applicable, Google will also transfer this information to third parties, insofar as this is legally prescribed, or insofar as third parties process this information on behalf of Google.
You can deactivate Google Analytics by means of a browser add-on, should you not want the website analysis. You can download the add-on here: https://tools.google.com/dlpage/gaoptout?hl=en .
Demographic characteristics and interests with Google Analytics
We use the "demographic characteristics" and "interests" functions of Google Analytics. Using these functions, reports can be created that contain statements about the age, gender and interests of visitors to the website. This data comes from interest-based advertising from Google as well as visitor data from third-party providers. It is not possible to assign this data 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 item "Objection to data collection".
Google signals are session data from websites and apps that Google links to users who are logged into their Google account and have activated personalised advertising. Linking data to these logged-in users enables cross-device reporting, cross-device remarketing and the export of cross-device conversions to Google Ads.
The use of Google Analytics with Conversion Tracking and Google Signals takes place on the basis of your consent and thus in accordance with Article 6 para. 1 sentence 1 lit. a) GDPR.

By that you will receive regular messages about the event you have selected and the corresponding offer.
To opt in, you must confirm your browser's request to receive notifications. This process is documented and stored by CleverPush. This includes saving the opt in time and your browser ID or device ID. The collection of this data is required so that we can understand the processes in case of misuse and therefore serves our legal protection. To show you the push notifications, CleverPush collects and processes your browser ID on our behalf and your device ID in the case of mobile access. By subscribing to our push notifications, you agree to their receipt. Legal basis for the processing of your data after registration for our push notifications is in the presence of your consent Art. 6 (1) (a) GDPR.
CleverPush also statistically evaluates our push notifications. CleverPush can detect if and when our push notifications were displayed and clicked by you. This enables us to determine which push notifications are of interest to recipients, in order to match future messages to the presumed interests of all recipients and thus increase interest in our offer. In addition to the push token or device ID, we also store the focus of the app on which the push notifications were activated (e.g. business, sports, etc.). We also use this information to send push notifications to the respective subscribers who are in their presumed interests. The legal basis of the processing is in each case Art. 6 (1) (f) DSGVO. A push token or device ID is only assigned to a specific person if we should be legally obliged to do so, to defend against claims against us if this is required as evidence, and to prosecute any violations of the law.
Your consent to the storage and use of your personal information to receive our push notifications and the statistical survey described above may be revoked at any time with future effect. Furthermore, you can withdraw to the use of personal data described above at any time on the basis of Art. 6 (1) (f) DSGVO.

If you use our push notifications on a desktop PC with the operating system "Windows", you can also unsubscribe our push notifications by right-clicking on the respective push notification in the settings that appear there.
Your data will be deleted as soon as they are no longer necessary to achieve the purpose of their survey. Your data will be stored as long as the subscription to our push notifications is active.
Under the following link, the process of unsubscribing will be explained in detail: https://cleverpush.com/faq .
To accelerate the retrieval of content (e. g. images) and to defend against attacks, CleverPush uses the offers from cloudflare.com, an offer from Cloudflare, Inc., within the scope of order processing based on the standard contractual clauses.
CleverPush does not store any data on Cloudflare's servers that contain personal data, but only general content such as text or images. When this content is called up, the end device you are using establishes a connection to Cloudflare and this leads to the processing of the IP address of the end device you are using.
