1. What are cookies?
Cookies are commonly used on websites to track site usage and trends, to improve quality of service, to enhance user’s experience and to deliver third-party services connected to a website. Cookies are small text files which a website may put on your computer or mobile device when you first visit a site or page in order to remember your user preferences, help analyse the website’s performance and to recommend content relevant to your visit. The cookie will help the website, or another website, to recognise your device the next time you visit. Most cookies won’t collect information that identifies you, and will instead collect more general information such as how users arrive at and use websites, or a user’s general location. A cookie cannot retrieve any other data from your hard drive or pass on computer viruses.
You can configure your browser to inform you about the use of cookies so that you can decide on a case-by-case basis whether to accept or reject a cookie. Alternatively, your browser can be configured to automatically accept cookies under certain conditions or to always reject them, or to automatically delete cookies when closing your browser. Disabling cookies may limit the functionality of websites.
A website operator has a legitimate interest in the storage of cookies to ensure an optimized service provided free of technical errors.
Cookies which are necessary to allow electronic communications or to provide certain functions you wish to use on our Sites are stored pursuant to Art. 6 paragraph 1, letter f of DSGVO.

There are different type of cookies.
First Party Cookies - these are set by the website that is being visited and only that website can read them. In addition, a website might use a separate company to analyse how people are using their site. Such a separate company may set their own cookie(s) to do this.
Third Party Cookies - these are set by someone other than the owner of the website being visited.
Advertising Cookies - some websites use advertising networks to show specially targeted adverts when their sites are being visited. These networks may also be able to track browsing across different sites.
Session Cookies - these are stored while a website is being browsed. They get deleted from a user’s device when his/ her browser is being closed, for e.g. Internet Explorer, Chrome, Firefox or Safari.
Persistent Cookies - these are saved on a user’s computer. They do not get deleted when the user’s browser is being closed. Persistent cookies are being used when it is needed to remember a user for more than one browsing session. For example, they are being employed to remember preferences set for a user’s next visit to the Sites, or to recognize a user once signed in to a site - all helping to enhance the user’s experience of a site.
Cookies can be removed or blocked by using browser settings, but in some cases doing so may prevent a website from fully functioning. To find out more about cookies, including how to manage and delete them, you may visit
2. Use and management of cookies
Cookies are being used to remember user’s preferences and to tailor the Sites to user’s interests.

First Party Cookies are not being used.

Third Party Cookies
Some of the Sites may contain content from other sites like for example YouTube, which may set their own cookies. BLUESTER GMBH has no control over third party cookies.
Google Analytics is being used to help understand how users use the Sites. Google Analytics cookies do not provide any personally identifiable information. They show how users arrived at the Sites, if users have visited the Sites before, how long they stay on the Sites, and which pages on the Sites they visited. Google Analytics cookies can also provide general information about where in the world a user may be located. This information helps to understand how people use the Sites, and it gives information about the kind of experience people have on the Sites, all of which in a legitimate interest helps to learn how to make the experience on the Sites and its advertising better.

Google Analytics is operated by Google Inc., 1600 Amphitheatre Parkway,
Mountain View, CA 94043, USA. The information generated by Google Analytics about your use of the Sites is usually transmitted to a Google server in the USA and stored there. Google Analytics cookies are stored based on Art. 6(1) (f) DSGVO.

We have entered into an agreement with Google for the outsourcing of our data processing and fully implement the strict requirements of the German data protection authorities when using Google Analytics.

We have activated the IP anonymization feature on the Sites. Your IP address will be shortened by Google within the European Union or other parties to the Agreement on the European Economic Area prior to transmission to the United States. Only in exceptional cases is the full IP address sent to a Google server in the US and shortened there. Google will use this information on behalf of us to evaluate your use of the Sites, to compile reports on website activity, and to provide other services regarding website activity and Internet usage for the website operator. The IP address transmitted by your browser as part of Google Analytics will not be merged with any other data held by Google.

You can prevent Google Analytics cookies being stored by selecting the appropriate settings in your browser. However, we wish to point out that doing so may mean you will not be able to enjoy the full functionality of the Sites. You can also prevent the data generated by cookies about your use of the website (incl. your IP address) from being passed to Google, and the processing of these data by Google, by downloading and installing the browser plugin available at the following link:

You can prevent the collection of your data by Google Analytics by clicking on the following link. An opt-out cookie will be set to prevent your data from being collected on future visits to this site: Disable Google Analytics.
For more information about how Google Analytics handles user data, see Google's privacy policy:

The Sites also use Google Analytics' demographic features. This allows reports to be generated containing statements about the age, gender, and interests of site visitors. This data comes from interest-based advertising from Google and third-party visitor data. This collected data cannot be attributed to any specific individual person. You can disable this feature at any time by adjusting the ads settings in your Google account or you can forbid the collection of your data by Google Analytics as described in the section "Refusal of data collection".

For uniform representation of fonts, the Sites use web fonts provided by Google. When you open a page, your browser loads the required web fonts into your browser cache to display texts and fonts correctly. For this purpose your browser has to establish a direct connection to Google servers. Google thus becomes aware that our web page was accessed via your IP address. The use of Google Web fonts is done in the interest of a uniform and attractive presentation of our website. This constitutes a justified interest pursuant to Art. 6 (1) (f) DSGVO.
If your browser does not support web fonts, a standard font is used by your computer.
