Data privacy statement of STL GmbH

1. Introduction

With the following information we would like to give you as the “data subject” an overview of the processing of your personal data by us and your rights under data protection laws. Our website can generally be used without entering personal data. However, if you would like to make use of special services provided by our company via our website, it may be necessary to process personal data. If the processing of personal data is necessary and there is no legal basis for such processing, we will generally obtain your consent.

The processing of personal data, for example your name, address, or e-mail address, always takes place in accordance with the General Data Protection Regulation (GDPR) and in accordance with the country-specific data protection regulations applicable to “STL GmbH”. With this data protection declaration, we would like to inform you about the scope and purpose of the personal data we collect, use and process.

As the controller, we have implemented numerous technical and organizational measures to ensure the most complete protection possible for personal data processed through this website. Nevertheless, internet-based data transmissions can generally have security gaps, so that absolute protection cannot be guaranteed. For this reason, you are free to transmit personal data to us in alternative ways, for example by telephone or by post.

4. Legal basis for processing

Art. 6 para. 1 lit. a GDPR (in conjunction with § 15 para. 3 TMG) serves our company as the legal basis for processing operations for which we obtain consent for a specific processing purpose.

If the processing of personal data is necessary to fulfil a contract to which you are a party, as is the case, for example, with processing operations that are necessary for the delivery of goods or the provision of other services or consideration, the processing is based on Art. 6 para. 1 lit. b GDPR. The same applies to such processing operations that are necessary to carry out pre-contractual measures, for example in cases of inquiries 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 Article 6 (1) (c) GDPR.

In rare cases, it may be necessary to process personal data to protect the vital interests of the data subject or another natural person. This would be the case, for example, if a visitor to our company were injured and his name, age, health insurance data or other vital information would have to be passed on to a doctor, hospital or other third party. The processing would then be based on Article 6 (1) (d) GDPR.

Ultimately, processing operations could be based on Article 6 (1) (f) GDPR. Processing operations that are not covered by any of the aforementioned legal bases are based on this legal basis if the processing is necessary to safeguard a legitimate interest of our company or a third party, provided that the interests, fundamental rights and freedoms of the person concerned do not prevail. We are particularly permitted to carry out such processing operations because they have been specifically mentioned by the European legislator. In this respect, he took the view that a legitimate interest could be assumed if you are a customer of our company (recital 47 sentence 2 GDPR).

5. Technology

5.1. SSL / TLS encryption

To ensure the security of data processing and to protect the transmission of confidential content, such as orders, login data or contact requests that you send to us as the operator, this site uses an SSL or. TLS encryption. You can recognize an encrypted connection by the fact that in the address line of the browser there is an “https: //” instead of “http: //” and by the lock symbol in your browser line.

We use this technology to protect your transmitted data.

5.2. Data collection when visiting the website

If you only use our website for informational purposes, i.e. if you do not register or otherwise provide us with information, we only collect data that your browser transmits to our server (in so-called “server log files”). Our website collects a range of general data and information each time you or an automated system access a page. These general data and information are stored in the server’s log files. The

  1. browser types and versions used,
  2. the operating system used by the accessing system,
  3. the website from which an accessing system reaches our website (so-called referrer),
  4. the sub-websites that are accessed via an accessing system on our website,
  5. the date and time of access to the website,
  6. a shortened internet protocol address (anonymised IP address),
  7. the internet service provider of the accessing system.

When using this general data and information, we do not draw any conclusions about your person. Rather, this information is needed to

  1. deliver the content of our website correctly,
  2. to optimize the content of our website and the advertising for it,
  3. to ensure the long-term functionality of our IT systems and the technology of our website and
  4. to provide law enforcement authorities with the information necessary for law enforcement in the event of a cyber attack.

This collected data and information is therefore statistically evaluated by us on the one hand and furthermore with the aim of increasing data protection and data security in our company in order to ultimately ensure an optimal level of protection for the personal data processed by us. The anonymous data in the server log files are stored separately from all personal data provided by a data subject.

The legal basis for data processing is Art. 6 Para. 1 S. 1 lit.f GDPR. Our legitimate interest follows from the data collection purposes listed above.

7.  Contents of our website

7.1. Contact / contact form

When you contact us (e.g. using the contact form or email), personal data is collected. Which data is collected in the case of a contact form can be seen from the respective contact form. These data are stored and used exclusively for the purpose of answering your request or for establishing contact and the associated technical administration. The legal basis for processing the data is our legitimate interest in answering your request in accordance with Art. 6 Para. 1 lit.f GDPR. If your contact is aimed at concluding a contract, the additional legal basis for processing is Article 6 (1) (b) GDPR. Your data will be deleted after your request has been processed; this is the case if it can be inferred from the circumstances that the matter in question has been settled and provided that there are no statutory retention requirements.

7.2. Application management / job exchange

We collect and process the personal data of applicants for the purpose of handling the application process. The processing can also be done electronically. This is particularly the case if an applicant sends us the relevant application documents electronically, for example by email or using a web form on the website. If we conclude an employment contract with an applicant, the data transmitted will be stored for the purpose of processing the employment relationship in compliance with the statutory provisions. If we do not conclude an employment contract with the applicant, the application documents will be automatically deleted two months after notification of the rejection decision, provided that deletion does not conflict with any other legitimate interests on our part. Another legitimate interest in this sense is, for example, a burden of proof in proceedings under the General Equal Treatment Act (AGG).

The legal basis for processing your data is Article 88 GDPR in conjunction with Section 26 Paragraph 1 BDSG.

8.  Our activities in social networks

So that we can communicate with you in social networks and provide information about our services, we are represented there with our own pages. If you visit one of our social media pages, we are jointly responsible with the provider of the respective social media platform within the meaning of Art. 26 GDPR with regard to the processing operations triggered by this, which concern personal data.

We are not the original provider of these pages, but only use them within the scope of the possibilities offered by the respective provider.

Therefore, we would like to point out as a precaution that your data may also be processed outside the European Union or the European Economic Area. Use can therefore have data protection risks for you, as it can be more difficult to safeguard your rights, e.g. to information, deletion, objection, etc. and the processing in the social networks often takes place directly for advertising purposes or to analyze user behavior by the provider without this can be influenced by us. If the provider creates user profiles, cookies are often used or the user behavior is assigned directly to your own member profile of the social networks (provided you are logged in here).

The described processing of personal data is carried out in accordance with Art. 6 Paragraph 1 lit. can. If you have to give your consent to data processing as a user with the respective providers, the legal basis refers to Art. 6 Para. 1 lit. a GDPR in conjunction with Art. 7 GDPR.

Since we have no access to the data kept by the providers, we would like to point out that it is best to apply your rights (e.g. to information, correction, deletion, etc.) directly to the respective provider. Further information on the processing of your data in the social networks and the possibility of making use of your right of objection or revocation (so-called opt-out) is listed below for the respective social network provider we use:
