In order to be able to inform you about current news by e-mail, we store your e-mail address and other voluntarily provided data when you register until revoked, for example for the targeted selection of topics that are relevant to you. For security reasons, we also store your IP address and the time of registration or confirmation. As soon as you have entered and sent your registration data, we will send you an e-mail to confirm and activate your free subscription by clicking on it ("double opt-in"). Only after confirmation you will receive our newsletter. The legal basis for the processing of the data after registration for the newsletter by the user is, if the user has given his consent, Art. 6 (1) lit. a GDPR.

You can unsubscribe from the newsletter at any time. You will find a link to unsubscribe in every newsletter email.

The stored data will only be used by us for the stated purposes. For the purpose of sending the newsletter, data is passed on to service providers in the area of newsletter services. The legal basis for this data processing is Art. 6 Para. 1 lit. f) GDPR in conjunction with § 7 of the German Act against Unfair Competition (UWG). Our "interest" as defined by Art. 6 (1) (f) is the administration and dispatch of our newsletters.

The data will be deleted as soon as they are no longer required to achieve the purpose for which they were collected. The user's first name, last name and e-mail address are therefore stored for as long as the subscription to the newsletter is active.

It may happen that we offer participation in competitions on our websites. For security reasons, your IP address and the time of registration are also stored when you enter. Once you have entered and submitted your registration details, we will send you an email to confirm your registration by clicking on it ("double opt-in"). This confirmation of your registration is required for participation in the competition. The legal basis for the corresponding processing of the data after registration for the competition is Art. 6 para. 1 lit. a GDPR if the registrant has given his consent.

You can revoke your consent to participate in a competition at any time by sending an e-mail to W. MÜLLER GmbH (see imprint).

The stored data will only be used by us for the stated purposes.

The data will be deleted as soon as it is no longer required to achieve the purpose for which it was collected.

We offer a contact form on our website which you can use to request information about our products or to make general contact. In addition to your message content, we require you to provide the following information: Last name, first name, company and e-mail.

We need this information to process your request, to address you correctly and to send you a reply.

Alternatively, it is possible to contact us via the e-mail addresses provided. In this case, the user's personal data transmitted with the e-mail will be stored.

Enquiries received via the contact form on our website or via the e-mail addresses provided are generally stored in our CRM system. The CRM system is regularly checked to determine whether data can be deleted. If data is no longer required in the context of a customer or interested party relationship or if a conflicting interest of the customer or interested party prevails, we will delete the relevant data, provided that there are no statutory retention obligations to the contrary.

The legal basis for this data processing is Art. 6 para. 1 lit. f) GDPR. Our "interest" within the meaning of Art. 6 (1) (f) is communication with customers and interested parties.

We offer an evaluation form on our website, through which you can evaluate assemblies carried out by us. We would be pleased if you would fill in this form for us in order to facilitate our quality control. Of course, you are free to decide whether you fill in the questionnaire voluntarily or not. There will of course be no negative consequences for you if you refuse to complete it.

If we receive your personal data as a result of an assembly assessment submitted by you, the corresponding data processing is carried out in order to safeguard our overriding, legitimate interests. Our interest within the meaning of Art. 6 Para. 1 lit. f) in this context lies above all in a quality control of the assembly services carried out. This quality control also includes your communicated assessments. Only in this way can we ensure that any quality or service deficiencies can be worked on immediately and in a targeted manner. This is essential for our successful order processing.

We process and store your personal data as long as it is necessary for the execution of a contact with you or for the execution of a contractual relationship and as long as it is necessary for the fulfilment of our contractual and legal obligations. If the data is no longer required for the fulfilment of contractual obligations, it is regularly deleted, unless its further processing for a limited period is required due to retention periods under commercial and tax law (e.g. German Commercial Code (HGB), the Fiscal Code of Germany (AO)). The periods specified there for storage or documentation are two to ten years. Longer storage is also possible if you have consented to this in accordance with Art. 6 Para. 1 Sentence 1 lit. a GDPR.

We process for the registration, conduct and processing of our seminars and webinars (hereinafter referred to as: courses) only purpose-related personal data (name of participant, company name and -address, e-mail, telephone number and account data) in electronic and written form, in order to organize the participant management and to enable a smooth process of the course. Supplementary notes on data processing regarding webinars via “Microsoft Teams” see below.
The legal basis for the scope of data collection is Art. 6 para. 1 lit. b) GDPR (performance of a contract), but in any case, our legitimate interest in a smooth implementation and processing of our courses (At. 6 para. 1 lit. f) GDPR). The participation in one of our webinars via “Microsoft Teams” is generally on a voluntary basis. We would like to contact you after the meeting. Therefore, we need your consent. You agree to the use of the personal data collected during the registration to the webinar, in order to contact you after the webinar. In case of a consent as the legal basis for the data processing, every data subject is entitled to revoke the consent at any time with effect for the future without giving reasons. For this an e-mail to the W. MÜLLER GmbH (see imprint) is sufficient.
If you decide not to provide the relevant data, we are not able to process your request or to enable a participation in our courses, since this is not possible without a corresponding participant management.
We archive your correspondence with us in connection with our courses. For the performance of our courses, we enter the data of participants electronically and – where appropriate – in printouts, to ensure a smooth process of the course. The collected data are used to register applications and to perform our courses properly. They are also helpful for us if participants or persons interested in our courses address our course management or e.g. the respective speaker.
Because you pay a participation fee after receipt of the invoice, we see your account data for example. We use your data to process your payment and the course by our accounting department. All account data you provide us with, are exclusively used for the purpose of fulfilling and processing your order. As soon as the contract is completely carried out and the fee is completely paid, your data are blocked for further use and will be deleted, after tax and commercial law regulations and retention periods have been satisfied. For the processing of participant data, the statements to the participant management shall apply.
In our courses, we possibly conduct surveys or evaluations to our courses by means of evaluation forms. It is important to us, to receive your comments and proposals to our offerings. The participation is voluntary, the data collection is carried out in an anonymized way. The collected data are gathered and analyzed separately from personal data. There shall be no person-related analysis or storage of the data unless this is part of the evaluation or it happened with your expressed consent. For the analysis of our offerings, we also create statistics to measure the number of participants regarding the single courses and to show them in our annual report. This is carried out exclusively in anonymized form and without a possible allocation to personal data.
We use the tool “Microsoft Teams” to carry out online webinars. “Microsoft Teams” is a service of the Microsoft Corporation, One Microsoft Way, Redmond, WA 98052-6399 based in the USA. With the use of MS Teams, Microsoft also receives certain personal data. Further information to the processing of your data by Microsoft in the use of Microsoft Teams, are for example available under:
Note: As far as you open the website of “Microsoft Teams”, the provider of “Microsoft Teams” is responsible for the data processing. Though a start of the website is only necessary for the use of “Microsoft Teams” to download the software for the use of “Microsoft Teams”. If you do not want to or cannot use the “Microsoft Teams-app”, you can also use “Microsoft Teams” via your browser. The service in so far then is also rendered by the website of “Microsoft Teams”.
In the use of “Microsoft Teams”, different types of data are recorded as well as processed. The extent depends on the data you voluntarily stated before the meeting.
•    User details: e.g. display name, maybe e-mail address, profile picture (optional), preferred language
•    Meeting metadata: e.g. date, time, Meeting-ID, telephone numbers, place
•    In case of recording: MP4 file of all video-, audio- and presentation recordings, MP4 file of all audio recordings, text file of the online-meeting-chat. If webinars are recorded, you are informed about that in advance before the beginning transparently and – if necessary – asked for a consent. A note to an actual recording is displayed in the webinar.
•    In case of a dial-up by telephone: outgoing and incoming telephone number, country code, start and end time, participant‘s IP address (optional)
•    Text-, audio- and video data: You can use the chat-, question- or survey functions in a webinar. Accordingly, your text input is processed and presented in the webinar. To enable the display of video and the playback of audio, during the meetings the data of the microphone of your terminal device as well as of a possible video camera of the terminal device are processed. You, as well as the organizer, can switch off or mute the camera or the microphone at any time via the “Microsoft Teams” applications. To participate a webinar, you at least need to give details on your name.
The chat contents are recorded during the use of “Microsoft Teams”. We store the chat contents for the duration of a month. If you are registered at “Microsoft Teams” as a user, the reports about online-meetings (meeting metadata, data to the telephone dial-up, questions and answers in webinars, survey function in webinars) can be stored up to one month at “Microsoft Teams”.
We do not use any automated decision-making according to Art. 22 GDPR.
All data we received from you are generally not passed to third parties without your expressed consent. Excepted from this regulation are service providers, which need the transmission of data for the execution of their job (e.g. the credit institute authorized with the processing of the payment). But in these special cases, the amount of transferred data pares down to the necessary minimum and exceptional to the necessary data of the transaction. The provider of “Microsoft Teams“ necessarily becomes aware of the above-named data, as far as this is intended within the frame of our order processing contract with “Microsoft Teams”. But the forwarding of the data takes place under the provision that the cooperation partners or the contracting authorities also commit themselves to the respective data protection guidelines. The data will not be passed to third parties for advertising purposes.
“Microsoft Teams” is a service of a provider located in the USA. Therefore, a processing of personal data is also proceeded in a third country. We concluded an order processing contract with the provider of “Microsoft Teams”, that meets the requirements of Art. 28 GDPR. An appropriate level of data protection is provided by the conclusion of the so-called EU standard contractual clauses. As complementary protective measures, we furthermore carried out our Microsoft Teams configuration in a way that e.g. for the implementation of webinars, only computer centers in the EU, the EEA are used.

If you voluntarily provide us with data, e.g. in forms, and this is not required for the fulfilment of our contractual obligations, we process this data on the basis that we assume that the processing and use of this data is in your interest.

Data that you provide to us will generally not be transferred to third parties. In particular, your data will not be passed on to third parties for their advertising purposes.

However, we may use service providers for the operation of these Internet pages or for other products of ours. Here it can happen that a service provider receives knowledge of personal data. We select our service providers carefully - especially with regard to data protection and data security - and take all measures required by data protection law for permissible data processing.

With the exception of processing operations for which we provide information about the possibility of transferring data to recipients based outside the EU in these notes on data protection, we do not transfer your data to recipients based outside the European Union or the European Economic Area. The data transfers take place on the basis of so-called standard contractual clauses of the EU Commission.

We process the data you have sent us in connection with your application in order to check your suitability for the position (or, if applicable, other open positions in our companies) and to carry out the application procedure.

The primary legal basis for the processing of your personal data in this application procedure is Section 26 BDSG in its current version. According to this, the processing of data required in connection with the decision on the establishment of an employment relationship is permissible.

Should the data be required for legal prosecution after the conclusion of the application procedure, data processing may be carried out on the basis of the requirements of Art. 6 GDPR, in particular to safeguard legitimate interests pursuant to Art. 6 (1) lit. f) GDPR. Our interest then consists of legal prosecution.

Data of applicants will be deleted after 6 months in case of rejection.

In the event that you have agreed to further storage of your personal data, we will transfer your data to our applicant pool. There, the data will be deleted after two years.

If you have been awarded a position during the application process, your data will be transferred to our personnel information system.

After receipt of your application, your applicant data will be viewed by the personnel department or the management. Suitable applications are then forwarded internally to the department responsible for the respective open position. Then the further procedure is coordinated. As a matter of principle, only those persons in the company have access to your data who require it for the proper conduct of our application procedure.
