Liability for links
References and links to third-party websites are beyond our scope of responsibility. Any responsibility whatsoever for such websites is refused. Accessing and using such websites always proceeds at risk to the user.

The copyrights and all other rights to content, images, photos and other files on the website belong exclusively to DTREU AG or the specifically named rights holders. Prior written consent of the copyright holder is required for reproduction of any elements.


Collection of personal data
Personal data will be collected where needed for orders, offers, participation in contests, etc. or we need it to fulfil contractual or legal obligations.

Use of personal data
On submitting personal data, you declare your consent that we collect your personal data and be able to assess it for marketing purposes. Your personal data may be shared within the company, not to third parties, and for later contacts (especially via e-mails) for the purpose of providing information about products, services and news. Your personal data can be shared with third parties if they process them on commission for us as vicarious agents or to render certain services, whereby data transfer to foreign countries is also possible. It will be made certain that any such data transfer will only proceed to a country that has equivalent data protections to those enjoyed in Switzerland.

Notice of data processing in connection with Google Analytics
This website uses Google Analytics, a web analysis service from Google Ireland Limited. If the party responsible for the data processing on this website is located outside of the European Economic Region or Switzerland, then the Google Analytics data processing will be carried out by Google LLC. Google LLC and Google Ireland Limited will be referred to below as “Google”.

Google Analytics uses so-called “Cookies”, text files which are stored on the computer of anyone who visits the site and make it possible to analyse how the visitor uses the site. The information about the site visitor’s use of the site generated by the cookie (including the shortened IP-address) will as a rule be transferred to a server owned by Google and stored there.

Google Analytics is only used on this website with the extension “anonymize”. This extension assures that the IP-address is rendered anonymous by shortening it and excludes any linking of the IP address with a person.  Using the extension, Google shortens the IP-address within member states of the European Union or in other contracting states signatory to the Treaty on the European Economic Region. The full IP-address will only be transferred to a server owned by Google in the USA in exceptional cases and it will then be shortened there.   The IP-address transferred by the specific browser in the framework of Google Analytics will not be combined with other data by Google.

On behalf of the site operator, Google will use the accumulated information to assess the use of the website, to generate reports about website activities and to perform other services associated with using the website for the site operator (Art. 6 Abs. 1 lit. f DSGVO). The justified interest in data processing lies in optimising this website, analysing the use of the website and adjusting the content. The interests of the users are sufficiently protected by using pseudonyms to protect anonymity.

Google LLC. is certified under the so-called Privacy Shield (list entry here) and on this basis guarantees an appropriate level of data privacy protection. The user identifications that are sent and the data linked with cookies, (e. g. user-ID) or advertising-IDs will be automatically deleted after 50 months. The deletion of data whose retention periods have expired, proceeds automatically in one month.

Collection of data by Google Analytics can be prevented if the person visiting the site changes the cookie-settings for this website. The collection and storage of the IIP-address and the data generated by cookies can also be denied at any time with future effect. The required browser plug-in ca be downloaded and installed under the following:

The person visiting the site can prevent Google Analytics from recording data on this website, by clicking on the following links. An opt-out-Cookie will be set which prevents recording data when visiting this website, etc.
