Privacy policy


Our website may be used without entering personal information. Different rules may apply to certain services on our site, however, and are explained separately below. We collect personal information from you (e.g. name, address, email address, telephone number, etc.) in accordance with the provisions of German data protection statutes. Information is considered personal if it can be associated exclusively to a specific natural person.

The legal framework for data protection may be found in the German Federal Data Protection Act (BDSG) Bundesdatenschutzgesetz (BDSG) and the Telemedia Act (TMG). Telemediengesetz (TMG).

Server Data

For technical reasons, data such as the following, which your internet browser transmits to us or to our web space provider (so called server log files), is collected:

  • websites that you visit
  • date and time of your visit
  • data volume transferred
  • report of successful retrieval
  • type and version of the browser you use
  • operating system
  • websites that linked you to our site (referrer URL)
  • your Internet Protocol (IP) address

This anonymous data is stored separately from any personal information you may have provided, thereby making it impossible to connect it to any particular person. The data is used for statistical purposes in order to improve our website and services.

Per­sonal data

Per­sonal data are individual details about per­sonal or factual cir­cum­stances of a specific or iden­ti­fiable natural person. This includes informa­tion such as name, address, telephone number and birth date. Informa­tion which is not directly related to the real iden­tity of a person – e.g. visited web­sites or number of users of a web­site – is not per­sonal data.

Contacting us

On our website we offer you the opportunity to contact us, either by email and/or by using a contact form. In such event, information provided by the user is stored for the purpose of facilitating communications with the user. No data is transferred to third parties. Nor is any of this information matched to any information that may be collected by other components of our website.

Linking of services and third-party content

It is possible that there may be links on this online site to third-party content such as videos from YouTube, map material from Google Maps, RSS feeds or graphics from other websites. This always requires that the providers of this content (hereinafter referred to as „third-party providers“) become aware of the users‘ IP addresse. Without the IP address, they could not send the content to the respective user‘s browser. The IP address is therefore essential for presenting such content. We make an effort to use only content for which the relevant providers use the IP address only for delivering the content. However, we cannot inluence the use if the third-party providers store the IP addresses for statistical purposes, for example. If we are aware of this, we will inform the users.


In several places of this web­site, coo­kies are used which serve to make the site more user-fri­endly, effec­tive and safe. Coo­kies are small text files allowing for the reco­gni­tion of users. They are stored by the browser memory on the com­puter of the user. Most of the coo­kies used by Gretsch­-Unitas are so-called "ses­sion coo­kies" which are automati­cally deleted after the user has left the web­site.

We also use "perma­nent coo­kies" in order to capture informa­tion about users who repea­tedly visit the web­site. In this way an optimum user guidance is achieved, and the web­site user is offered the grea­test pos­sible variety and availability of new con­tent. The con­tent of a per­sis­tent cookie is limited to an iden­ti­fica­tion number. Name, IP address etc. are not stored.

Using this web­site is also pos­sible wit­hout coo­kies. Users can deac­tivate the sto­rage of coo­kies in their browser, or limit the sto­rage to specific web­sites, or adjust their browser in a way that it noti­fies the arrival of a cookie. User also can delete coo­kies from their hard disc. In this case, only a limited page pre­senta­tion and limited user guidance are pos­sible.

You can manage many online-advertisement-cookies via the US-American website or the EU-website
