Legal basis of the processing

Art. 6 I lit. a GDPR serves as a legal basis for processing operations of our company for which we obtain consent for a specific processing purpose. If the processing of personal data is necessary for the fulfilment of a contract to which the concerned person is a contractual party, as is the case for example with processing operations necessary for the delivery of goods or the provision of other services or consideration, the processing is based on Art. 6 I lit. b GDPR. The same applies to such processing operations that are necessary to carry out pre-contractual measures, for example in cases of requests about our products or services. If our company is subject to a legal obligation which requires the processing of personal data, for example to fulfil tax obligations, the processing is based on Art. 6 I lit. c GDPR.

Duration for which the personal data is stored

The criterion for the duration of the storage of personal data is the respective legal retention period. After the expiry of this period, the corresponding data will be routinely deleted, provided that it is no longer necessary for the fulfilment or initiation of the contract.


Kettenwulf Betriebs GmbH uses technical and organisational security measures to protect your personal data from accidental or intentional manipulation, loss, destruction or access by unauthorised persons.

Our security measures are continuously improved and adapted in line with technological developments.

Trademarks and copyright

If no other reference is given, all trademarks and copyrights are subject to Kettenwulf Betriebs GmbH. This includes photos, graphics, texts as well as any kind of multimedia data such as sounds and videos.

Passing on or use of this content is only permitted with the express permission of Kettenwulf Betriebs GmbH.

Social Media activities

We provide online presences within social networks in order to communicate with the interested parties and users and to inform them about us.

User data may be processed by the service provider outside the territory of the European Union. This may result in risks to users because, e.g. the enforcement of user rights could be made more difficult.

The service provider generally processes users’ data for market research and advertising purposes. Thus, e.g. users’ interests arising from the user behavior are used, e.g. showing ads inside and outside the platforms that might be in the interests of users. Cookies are usually stored on users’ computers for this purpose. In addition, in the usage profiles, data can also be stored independently of the devices used (in particular if the users are members of the respective platforms and are logged in).

In the following, we will inform you about the processing of your personal data carried out by us in the context of the online presence provided by us. In its judgment of 5 June 2018, the EU confirmed the joint responsibility of the service providers and the site operator.

The social media page you visit gives you the opportunity to respond to our posts, comment on them, create a user post yourself, and send us private messages with personal concerns. The data provided in this context by you and possibly accessible to us (e.g. username, pictures, interests, contact details) are used by us exclusively for the purpose of customer and interest communication. Our interest lies in providing you with a platform on which we can provide you with up-to-date information and with the help of which you can address your request to us and we can fulfill your request as quickly as possible.

We do not undertake any further data processing in addition to the basic functions by means of the page. Please note that the service provider may use tracking tools as well as cookies, regardless of the use of the site by us.

For a detailed description of the respective processing and the possibilities of contradiction (opt-out), we refer to the following linked information of the provider.

Also in the case of requests for information and the assertion of user rights, we point out that these can be claimed most effectively from the providers. Only the providers have access to the data of the users and can directly take appropriate measures and provide information. If you still need help, then you can contact us.
