Data Protection Declaration

The protection of personal data is an important matter to us. Your data are protected within the scope of legal regulations. You will find information below concerning the data which are recorded during your visit to our homepage and how they are used.



When you access this or other websites, you transfer data to our web server via your internet browser.

This website uses Piwik, an open-source software for the statistical evaluation of visitor access. Piwik uses so-called cookies, text files which are stored on your computer and which enable the analysis of your use of the website. The information generated by the cookie on your use of the internet offer is stored on the provider’s server in Germany. The IP address is anonymised immediately after processing and before it is memorised. You can prevent the installation of the cookies by making the necessary adjustments to your browser software, but we must point out that if you do so, you may not be able to use all functions of the website to their full extent.

The following data are recorded during a running connection for communication between your internet browser and our web server:

  • IP address of the requesting computer
  • Provider and country of origin
  • Date and time of the request
  • Duration of visit
  • Internal search requests
  • Accessed site or name of the accessed file
  • Site from which the file was requested
  • Access status (file transferred, file not found etc.)
  • Quantity of data transferred
  • Web browser and operating system used

The stored data are used exclusively for statistical purposes and to improve our internet offer. They are not passed on to any third parties.

Within our website, the option exists of entering personal data (E-mail address, name) in order to make use of offers:

  • Info letters

In the info letter, we inform you about all current topics. If you would like to receive the info letter, we require a valid e-mail address along with information which allows us to verify that you are the holder of the e-mail address given and/or that the owner consents to the receipt of the info letter. No further data is collected. The data are only used to send the info letter and are not passed on to any third parties. When you register for the info letter, we memorise your IP address and the date of registration. This serves purely as evidence in the event that a third party misuses an e-mail address and registers for the receipt of the info letter without the knowledge of the authorised person.

  • Protected areas

Auditors with approval for the QS scheme can log into a protected area with their user name and password. This data is divulged by the user on an expressly voluntary basis. Here too, your data are treated confidentially and are not passed on to any third party.

Linking with third party services and contents (Slideshare)

It can happen within this online offer that third party contents are linked in by other websites. The prerequisite for this is always that the providers of these contents know the IP address of the users, because they cannot send the content to the browser of each user without the IP address. We have no influence on whether or not third party providers store IP addresses for statistical and similar purposes.



We use cookies in several areas. Most of the cookies we use expire at the end of the browser session, but others remain on the computer so that we can recognise your computer when you make your next visit. These cookies memorise the individual selections made by each user so that they can restore them in the same condition they were left in when a page is called up again. No link is made to personal data.

You can set your browser in such a way that you are either notified that cookies have been set, can decide on a case-to-case basis whether to accept cookies, or fundamentally refuse to accept them. The functionality of our website can be restricted if you do not accept cookies.



The Twitter link is not connected to our site via a Twitter social plugin. The connected Twitter link merely contains an http link to our Twitter site, which means that no direct link to the Twitter servers is made when our site is accessed.


Contact with the provider

If you contact QS via the contact form or per e-mail, the details of the user are stored for the purpose of processing the inquiry and in case there are any connection questions.


Electronic mail

It is possible that any information you send to us unencrypted per electronic mail (e-mail) might be read by third parties during the transmission process. We cannot usually check your identity either, so we do not know who is actually behind an e-mail address. This means that legally secure communication is not guaranteed with e-mail. We use filters against undesired advertising (SPAM filters) which in rare instances erroneously and automatically classify normal e-mails as undesired advertising and delete them. E-mails which contain damaging programs (viruses) are also deleted automatically.

If you want to send information to us which requires protection, we recommend that you either encrypt it and sign it electronically too if necessary in order to prevent unauthorised access and falsification during the transmission process, or that you send us the data per regular mail.
