B. Scope of processing of personal data, purpose of processing

1. Access to our website and creation of log files

a) Description of data processing, storage

Each time you access our website, our system automatically collects data and information from the computer system of the accessing computer.

The following data is collected:

  • Information about the browser type and the version used,
  • the operating system of the user,
  • the IP address of the user,
  • date and time of access,
  • websites from which the user's system accesses our website (referrer URL),
  • the subpages of our homepage called up by the user,
  • name of the downloaded file,
  • message as to whether the call was successful

These data are deleted from the log files of the system after 7 days, unless their further processing is exceptionally necessary to protect our legitimate interests (e.g. to cause a blocking of IP addresses, to file a criminal complaint). The data will then be erased as soon as they are no longer required for the purpose of their collection.
These data will not be stored and/or combined with other personal data of the user.

b) Purpose and legal basis of data processing

The data mentioned under a) shall be collected,

  • to enable delivery of the website to the user's computer. The legal basis for this is Art. 6 paragraph 1, lit. (f) GDPR. The temporary recording of the IP address to display the pages called up by the user is technically necessary for this and represents a legitimate interest pursued by us within the meaning of Art. 6 paragraph 1 sentence 1 (f) GDPR, which does not conflict with any overriding interests of the user.
  • in order to ensure the security of our web server and the trouble-free operation of our website, e.g. monitoring to prevent or detect hacker attacks. The purposes mentioned represent a legitimate interest pursued by us within the meaning of Art.6 paragraph 1 sentence 1 (f) GDPR, which does not conflict with any overriding interests of the user.

c) Disclosure / recipient(s) of data

The collected data will be stored by our web hosting provider, who works on our behalf and provides us with storage space for our website. In addition, our web hosting provider furnishes other related services, such as storing the associated data processing operations, ensuring that the website is accessible on the Internet. The service provider is established in the European Union or in a country of the European Economic Area.

The data collected in accordance with a) will not be disclosed to third parties, unless this is necessary in the event of attacks on our IT, see b) above, for example within the scope of a criminal complaint filed with the law enforcement authorities.

d) The possibility of objection

The collection of the IP address for the provision of the website, and the storage of the data in log files is absolutely necessary for the operation of the website. Consequently, there is no possibility of objection on the part of the user. With regard to the other personal data processed in accordance with 1 a), you shall have the right to object to the processing at any time for reasons arising from your particular situation, cf. the further information under Section C.

2. Contact form and establishment of contact by email by the user

a) Description of data processing, storage

Several contact forms are available on our website which can be used for electronic contact. If you take this opportunity as a user, then the data you enter in the input mask will be transmitted to us. The email address, the subject and your message are mandatory fields. The provision of further information is voluntary and will be used to contact you by telephone or personally, if necessary.

In addition, we collect and store the following data in each case:

  • Your IP addresses and
  • Date and time your enquiry was sent.

Alternatively, you can contact us via the email addresses provided by us. In this case, the personal data of the user transmitted with the email will be stored.

The data will be used to answer the enquiry. If you provide us with your name and postal address, we will process these data in accordance with section B 3. (postal advertising).

The data will be erased as soon as they are no longer required for the purpose which they have been collected for. This shall not apply to data we require for postal advertising, as long as you do not object to this use. If the enquiry relates to a concluded contract or a contract under negotiation, the communication contents and times will be stored until any claims arising therefrom are time-barred.

Otherwise, the personal data from the input mask of the contact form and those data sent by email will be restricted for further processing and will only be used to defend against possible legal claims once the respective conversation with the user has ended. The conversation is regarded to be terminated when it can be inferred from the circumstances that the relevant facts have been definitely settled. After expiry of the limitation period, the data will be deleted.

The additional personal data collected during the sending process will be erased after a period of seven days, at the latest.

b) Purpose & legal basis of data processing

The processing of personal data from the input mask takes place for the processing (handling) of the contact requests. Your email address and any other data you might provide will be stored in order to answer your enquiry. The legal basis for this is Art. 6 paragraph 1 lit. (f) GDPR. The same shall apply to your communication with us by email.

The purpose of storing your IP address and the time of establishing contact is to provide evidence of your enquiry and, if necessary, to clarify any possible misuse of your personal data. The legal basis for the processing of this data is also Art. 6 paragraph 1 lit. (f) GDPR.

If the purpose of establishing contact is to conclude a contract, the additional legal basis for the processing is Art. 6 paragraph 1 lit. (b) GDPR.

c) Disclosure

In this context, data shall not be disclosed to third parties. The data will be used exclusively for processing and answering the contact request.

The collected data will be stored by our web hosting provider who works on our behalf and provides us with storage space for our website, and he stores the associated data processing procedures. This service provider has been carefully selected and commissioned by us, is bound by our instructions and is controlled regularly. The service provider is established in the European Union or in a country of the European Economic Area.

d) Possibility/right of objection and removal

The user can object to the use of his personal data at any time. In such a case, the conversation cannot be continued. Section C applies in addition.

3. Postal advertising (letter post)

a) Description of data processing, storage, purpose, disclosure

If you provide us with your name and postal address, we will save them for the possible future despatch of postal advertising (letter post) on our products. If necessary, the data will be made accessible to an external service provider during franking and despatch. This service provider acts in accordance with our instructions and on our behalf. This service provider is established in the European Union. Any other disclosure to third parties will not take place. The data will be deleted as soon as they are no longer required for the purpose of their collection, or when you have objected to the processing.

b) Legal basis of the data processing, possibility/right of objection

The legal basis for the data processing mentioned under a) is Art. 6 paragraph 1 lit. (f) GDPR. The sending of product information by letter post is a legitimate interest of our company. You shall have the right to object to this use of your personal data at any time. In such a case, we will cease sending the letter post advertising. Section C applies in addition.

C. Rights of the concerned person(s) / data subject

As a concerned person or data subject, you shall have the right to free information about your personal data stored by us and, if applicable, the right to rectification, restriction of processing, erasure, information to third parties, data portability, objection, withdrawal of consent granted under data protection law, non-implementation of automated decisions and/or complaint to be lodged with the responsible data protection supervisory authority.

As long as it is not yet clear whether the legitimate grounds of the responsible controller override your reasons, the processing of the data will be restricted.

Where the processing of personal data concerning you has been restricted, such personal data shall, with the exception of storage, only be processed with your consent or for the establishment, exercise or defence 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 Union or of a Member State.

If the processing has been restricted in accordance with the above conditions, you shall be informed by us, as the responsible controller, before the restriction of processing is lifted.

4. Right to erasure

c) Exceptions

The right to deletion and information to third parties shall not apply to the extent the processing is necessary:

  • for exercising the right of freedom of expression and information;
  • for compliance with a legal obligation which requires processing by Union or Member State law to which we as the responsible controller are subject, or for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller;
  • for reasons of public interest in the area of public health in accordance with Art. 9 paragraph 2 lit. (h) and (i) and Art. 9 paragraph 3 GDPR;
  • for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Art. 89 paragraph 1 GDPR, insofar as the right referred to under section a) is likely to render impossible or seriously impair the achievement of the objectives of such processing; or
  • for the establishment, exercise or defence of legal claims.

5. Right to information

We shall notify all recipients to whom your personal data has been disclosed of any rectification, erasure or restriction of processing, unless this proves to be impossible or involves disproportionate effort.

You shall have the right vis-à-vis us, as the responsible data controller, to be informed about those recipients.

6. Right to data portability

You shall have the right to receive the personal data concerning you, which you have provided to us as the responsible controller, in a structured, commonly used and machine-readable format. In addition, you shall have the right to transmit those data to another responsible controller without hindrance from us as the responsible controller, to which the personal data have been provided, to the extent:

  • the processing is based on consent pursuant to Art. 6 paragraph 1 lit. (a) GDPR or Art. 9 paragraph 2 lit. (a) GDPR or on a contract pursuant to Art. 6 paragraph 1 lit. (b) GDPR, and
  • the processing is carried out by automated means.

In exercising this right, you shall have the further right to have your personal data transmitted directly from us as the responsible controller to another responsible controller to the extent this is technically feasible. This shall not adversely affect the rights and freedoms of other persons.

The exercise of the right to data portability shall not apply to processing personal data necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in us as the responsible data controller.

7. Right to object

You shall have the right to object, on grounds relating to your particular situation, at any time to processing of your personal data which is based on Art. 6 (1) lit. (e) or (f) GDPR, including profiling based on those provisions.

We as the controller shall no longer process the personal data relating to you unless we demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms or for the establishment, exercise or defence of legal claims.

Where your personal data are processed for direct marketing purposes, you shall have the right to object at any time to processing of personal data concerning you for such marketing, which includes profiling to the extent that it is related to such direct marketing.

Where you object to processing for direct marketing purposes, the personal data concerning you shall no longer be processed for such purposes.

8. Right to withdraw the declaration of consent under data protection law

You shall have the right to withdraw your declaration of consent under data protection law at any time. Withdrawal of your consent will not affect the lawfulness of processing based on your consent before its withdrawal.

9. Automated individual decision-making including profiling

You shall have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning you or similarly significantly affects you.

This shall not apply, if the decision

  • a) is necessary for entering into, or performance of, a contract between you and us as the responsible party (as the data controller),
  • b) is authorised by Union or Member State law to which we are subject as responsible data controller and which also lays down suitable measures to safeguard your rights and freedoms and your legitimate interests; or
  • c) is based on your explicit consent.

However, these decisions shall not be based on special categories of personal data pursuant to Art. 9 paragraph 1 GDPR, unless Art. 9 paragraph 2 lit. (a) or (g) applies and suitable measures have been taken to safeguard your rights and freedoms as well as your legitimate interests.

In the cases referred to in (a) or (c), we as the responsible data controller shall implement suitable measures to safeguard your rights and freedoms, as well as your legitimate interests, including at least the right to obtain human intervention on our part as the responsible controller, to express our own position and to contest the decision.

10. Right to lodge a complaint with a supervisory authority

Without prejudice to any other administrative or judicial remedy, you shall have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your residence, place of work or place of alleged infringement, if you consider that the processing of your personal data infringes the GDPR.

The supervisory authority with which the complaint has been lodged shall inform the complainant on the progress and the outcome of the complaint, including the possibility of a judicial remedy pursuant to Art. 78 GDPR.
