e) Cookies
Our websites use so-called “cookies.” Cookies are small data packets and do not cause any damage to your device. They are either stored temporarily for the duration of a session (session cookies) or permanently (permanent cookies) on your device. Session cookies are automatically deleted at the end of your visit. Permanent cookies remain stored on your device until you delete them yourself or your web browser automatically deletes them. Cookies may originate from us (first-party cookies) or from third-party companies (so-called third-party cookies). Third-party cookies enable the integration of certain services from third-party companies within websites (e.g., cookies for processing payment services). Cookies have various functions. Many cookies are technically necessary, as certain website functions would not work without them (e.g., displaying stock prices). Other cookies can be used to evaluate user behavior or for advertising purposes. Cookies that are necessary for carrying out the electronic communication process, for providing certain functions you have requested (e.g., the shopping cart function), or for optimizing the website (necessary cookies), are stored on the basis of Art. 6 (1) (f) GDPR, unless another legal basis is specified. The website operator has a legitimate interest in the storage of necessary cookies for the technically error-free and optimized provision of its services. If consent to the storage of cookies and comparable recognition technologies has been requested, processing is carried out exclusively on the basis of this consent (Art. 6 (1) (a) GDPR and § 25 (1) TDDDG); consent may be revoked at any time. 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 closing the browser. If you deactivate cookies, the functionality of this website may be restricted. You can revoke your cookie consent for this website at any time and adjust your cookie settings: Cookie consent / Cookie settings
Storage period
Unless a more specific storage period is specified in this privacy policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a legitimate request for deletion or revoke your consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g., retention periods under tax or commercial law); in the latter case, deletion will take place once these reasons no longer apply.
General information on the legal basis for data processing on this website
If you have consented to data processing, we process your personal data on the basis of Art. 6 (1) (a) GDPR or Art. 9 (2) (a) GDPR, if special categories of data are processed in accordance with Art. 9 (1) GDPR.

If you have consented to the storage of cookies or access to information on your end device (e.g., via device fingerprinting), data processing will also be carried out on the basis of Section 25 (1) TDDDG. Consent can be revoked at any time.
If your data is necessary for the performance of a contract or for the implementation of pre-contractual measures, we process your data on the basis of Art. 6 (1) (b) GDPR.

Data processing may also be carried out on the basis of our legitimate interest pursuant to Art. 6 (1) (f) GDPR. The relevant legal basis in each individual case is explained in the following paragraphs of this privacy policy.
Recipients of personal data
We only disclose personal data to external parties if this is necessary for the performance of a contract, if we are legally obliged to do so (e.g., disclosure of data to law enforcement authorities), if we have a legitimate interest in the disclosure pursuant to Art. 6 (1) (f) GDPR, or if another legal basis permits the disclosure of data.
When using processors, we only disclose our customers’ personal data on the basis of a valid data processing agreement. In the case of joint processing, a joint processing agreement is concluded.
Your rights as a data subject under the GDPR
a) Revocation of your consent to data processing
Many data processing operations are only possible with your express consent. You can revoke any consent you have already given at any time. The legality of the data processing carried out until the revocation remains unaffected by the revocation.
b) Right to object to data collection in specific cases and to direct marketing (Art. 21 GDPR)
IF DATA PROCESSING IS BASED ON ART. 6 (1) (E) OR (F) OF THE GDPR, YOU HAVE THE RIGHT AT ANY TIME, ON GROUNDS RELATING TO YOUR PARTICULAR SITUATION, TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA; THIS ALSO APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE RESPECTIVE LEGAL BASIS ON WHICH PROCESSING IS BASED CAN BE FOUND IN THIS PRIVACY POLICY. IF YOU OBJECT, WE WILL NO LONGER PROCESS YOUR PERSONAL DATA UNLESS WE CAN DEMONSTRATE COMPELLING LEGITIMATE GROUNDS FOR THE PROCESSING WHICH OVERRIDE YOUR INTERESTS, RIGHTS AND FREEDOMS, OR THE PROCESSING SERVES TO ASSERT, EXERCISE, OR DEFEND LEGAL CLAIMS (OBJECTION PURSUANT TO ART. 21 (1) GDPR).
IF YOUR PERSONAL DATA IS PROCESSED FOR THE PURPOSE OF DIRECT MARKETING, YOU HAVE THE RIGHT TO OBJECT AT ANY TIME TO THE PROCESSING OF PERSONAL DATA CONCERNING YOU FOR THE PURPOSE OF SUCH MARKETING; THIS ALSO APPLIES TO PROFILING TO THE EXTENT THAT IT IS RELATED TO SUCH DIRECT MARKETING. IF YOU OBJECT, YOUR PERSONAL DATA WILL SUBSEQUENTLY NO LONGER BE USED FOR THE PURPOSE OF DIRECT MARKETING (OBJECTION PURSUANT TO ART. 21 (2) GDPR).
c) Right to lodge a complaint with a supervisory authority

The right to lodge a complaint exists without prejudice to other administrative or judicial remedies.
d) Right to data portability
You have the right to receive data that we process automatically on the basis of your consent or in fulfillment of a contract, either to yourself or to a third party, in a commonly used, machine-readable format. If you request the direct transfer of the data to another controller, this will only be carried out where technically feasible.
e) Information, correction, and deletion
Within the framework of the applicable legal provisions, you have the right to obtain information free of charge at any time about your stored personal data, its origin and recipients, and the purpose of data processing, and, if applicable, a right to correct or delete this data. You can contact us at any time with any questions you may have on this topic or on the subject of personal data.
f) Right to restriction of processing
You have the right to request the restriction of the processing of your personal data. You can contact us at any time to do so. The right to restriction of processing applies in the following cases:
- If you dispute the accuracy of your personal data stored by us, we will usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.
- If the processing of your personal data was/is unlawful, you can request the restriction of data processing instead of deletion.
- If we no longer need your personal data, but you require it to exercise, defend, or assert legal claims, you have the right to request the restriction of the processing of your personal data instead of deletion.>
- If you have lodged an objection pursuant to Art. 21 (1) GDPR, a balancing of your interests and ours must be carried out. As long as it has not yet been determined whose interests prevail, you have the right to request the restriction of the processing of your personal data.
If you have restricted the processing of your personal data, these data – apart from their storage – may only be processed with your consent or for the assertion, exercise, or defense of legal claims, or for the protection of the rights of another natural or legal person, or for reasons of important public interest of the European Union or of a Member State.
SSL or TLS encryption
This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as orders or inquiries that you send to us as the site operator. You can recognize an encrypted connection by the fact that the address line of the browser changes from “http://” to “https://” and by the lock symbol in your browser line.
When SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.
Consent to cookies / Cookie settings
Our website uses its own consent technology to obtain your consent for the storage of certain cookies on your device or for the use of certain technologies, and to document this in compliance with data protection requirements.
Consent technology stores a cookie in your browser in order to be able to assign the consents you have given or their revocation.

Analytics tools
Matomo
This website uses the open source web analytics service Matomo.
With the help of Matomo, we – and our parent company, Salzgitter AG – are able to collect and analyze data about the use of our website by its visitors. In this way, we can, among other things, determine when certain page views take place and from which region they originate. In addition, we record various log files (e.g. IP address, referrer, browser and operating system used) and can measure whether our website visitors perform certain actions (e.g. clicks, purchases, etc.).
The use of this analytics tool is based on Art. 6 (1) (f) GDPR. The website operator has a legitimate interest in analyzing user behavior in order to optimize both its website offering and its advertising. Where corresponding consent has been requested, processing is carried out exclusively on the basis of Art. 6 (1) (a) GDPR and § 25 (1) TDDDG, insofar as the consent includes the storage of cookies or access to information on the user’s end device (e.g. device fingerprinting) within the meaning of the TDDDG. Consent may be withdrawn at any time.
We use IP anonymization for analysis with Matomo. In this process, your IP address is shortened before the analysis so that it can no longer be clearly attributed to you. We host Matomo exclusively on our own servers, ensuring that all analytics data remains with us and is not shared with third parties.
