Data Protection

Everything important at a glance

<span class=“text-bg“>Information for respondents</span>

You have been contacted by one of our interviewers and have questions about our company and data protection? Here we have compiled all relevant information for you. Please contact us if you have any questions.

Who contacted you?

TeleMatrix is a company based in Mainz and stands for serious telephone surveys and market research. We don’t do direct marketing and don’t want to sell you anything. We are only interested in your opinion for research purposes. For our studies, we collect the opinions of randomly selected people on various aspects of daily life within the framework of telephone surveys.

Why were you contacted?

As it is not possible to survey the entire population, a representative part of the population is systematically selected. You have been selected. In order for this so-called sample to actually reflect the population structure in all its facets (age, gender, origin…), it is important that all randomly selected persons participate in the survey.

Where does TeleMatrix get my phone / mobile number from?

Basically, there are two possible sources from which we could have your telephone number:

On the one hand, we have software that can generate almost all existing telephone numbers in Germany. From this large number of numbers, yours was randomly selected. However, this does not mean that we know your name and address or other things about you. We then only have a telephone number and the information from which municipality, which county and which federal state this number probably comes from. Nothing more.

The second possibility is that our client, i.e. the company or institution for which we conduct the survey, has your contact data because you are a customer or member. If, for example, this client wishes us to question his customers, he may provide us with your data, unless you have forbidden him to pass on your data for a market research survey.

Do you have to participate in the survey?

Your participation is of course voluntary. If you do not have time to talk to us, we will be happy to arrange a suitable alternative appointment with you. Please note: By participating in one of our surveys, you make an important contribution to providing the public with answers to economic and social questions. We would therefore be very pleased to hear from you. Of course, we will also inform you about the background and purpose of the respective study. Please contact us directly.

What happens to your data?

Your data will be made anonymous, i.e. your personal details such as your name or telephone number will be separated from your answers from the interview. The data is only passed on in aggregated form, i.e. in groups. We only need this information to be able to compare different groups (e.g. older and younger people, existing and new customers, etc.). It is not possible to draw any conclusions about your person from the results.

Does TeleMatrix have the right to use my data to contact me?

Many people believe that we should not have their contact details or should not use them because they have not given their consent.

However, this is not the case in most cases, as the basic European Data Protection Regulation allows us to use your data (e.g. your telephone number) to contact you asking you to participate in a survey. In most cases, the law does not require your consent.

However, there are exceptions, because in the case of particularly sensitive data, your consent is certainly required for this data to be passed on to us or used by us. These so-called “special categories of personal data” include information on racial and ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, health data, and data on sex life and sexual orientation.

As a rule, we obtain permission to use your data from Article 6(1)(f) of the Basic European Data Protection Regulation.


In addition, TeleMatrix, if it wishes to use your data, must observe certain regulations that ensure that this does not cause you any disadvantages. These are in detail these measures:

  • We may only use your data for the one survey for which we have asked you for an interview. We are not allowed to store your data for use in another study. We would only be allowed to do this if you gave us your consent.
  • We need to protect your information from access by people who do not need this access for their work on the survey. This means that even with TeleMatrix only those employees can view and process their data who have to do so because it is necessary for the work on a study.
  • We may not pass on or even sell your data to others, i.e. to persons or companies who are not involved in carrying out the survey.
  • What you tell us within a survey remains anonymous, i.e. your answers are not merged with information that someone might conclude that these answers come from you.

This also means, of course, that our clients for whom we carry out the studies will never know that the data and information originate from you. The evaluation of the survey data is carried out exclusively anonymously.

You contact details will be deleted three weeks after the end of the study.

What rights do I have when it comes to the use of my personal data?

You have:

  • the right to transparency (Art. 12 DSGVO)
  • the right to information (Art. 15 DSGVO)
  • the right to correction (Art. 16 DSGVO)
  • the right to cancellation (Art. 17 DSGVO)
  • the right to restrict processing (Art. 18 DSGVO)
  • the right to data transferability (Art. 20 DSGVO)
  • the right of objection (Art. 21 DSGVO)

The restrictions according to §§ 34 and 35 BDSG apply to the right of information and the right of deletion. In addition, you have the right to file a complaint with a supervisory authority if you believe that the processing of data concerning you violates the DSGVO (Article 77 DSGVO in conjunction with § 19 BDSG).

Any consent already given to the processing of personal data can be revoked at any time with future effect vis-à-vis TeleMatrix GmbH. This also applies to the revocation of declarations of consent issued to TeleMatrix GmbH or the commissioning companies prior to the validity of the basic data protection regulation, i.e. prior to 25 May 2018.

You have the right to object at any time for reasons arising from your particular situation to the processing of personal data concerning you, which takes place pursuant to Art. 6 para. 1e DSGVO and Art. 6 para. 1 f DSGVO; this also applies to profiling based on this provision within the meaning of Article 4 no. 4 DSGVO.

In the event of an objection, TeleMatrix GmbH will no longer process your personal data, unless compelling reasons worthy of protection can be proven for the processing, which outweigh your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.

The objection can be made form-free and should be addressed to:

TeleMatrix GmbH

Wilhelm-Theodor-Römheld-Str. 14

55130 Mainz
