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.

You can opt in to receive our push notifications. To send our push notifications, we use the delivery service "CleverPush", which is provided by CleverPush GmbH, Nagelsweg 22, 20097 Hamburg ("CleverPush").
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. To revoke consent, you can change the setting to receive push notifications in your browser. 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.
