Our website sometimes uses HTTP cookies to store user-specific data.
What exactly are cookies?
Whenever you surf the Internet, you use a browser. Well-known browsers include Chrome, Safari, Firefox, Internet Explorer and Microsoft Edge. Most websites store small text files in your browser. These files are called cookies.
Cookies store certain user data about you, such as language or personal page settings. When you return to our site, your browser transmits the “user-related” information back to our site. Thanks to the cookies, our website knows who you are and offers you your usual default settings. In some browsers, each cookie has its own file, in others, such as Firefox, all cookies are stored in a single file.
There are both first-party cookies and third-party cookies. First-party cookies are created directly by our site, third-party cookies are created by partner sites (e.g. Google Analytics). Each cookie is unique because each cookie stores different data. The expiration time of a cookie also varies from a few minutes to a few years. Cookies are not software programs and do not contain viruses, trojans or other “malware”. Cookies also cannot access information on your PC.
For example, cookie data may look like this:
- Name: _ga
- Expiration period: 2 years
- Usage: differentiation of website visitors
- Example value: GA1.2.1326744211.152321192673
A browser should support the following minimum sizes:
- A cookie should be able to contain at least 4096 bytes
- At least 50 cookies should be able to be stored per domain
- A total of at least 3000 cookies should be able to be stored
What types of cookies are there?
One can distinguish between 4 types of cookies:
Absolutely necessary Cookies
These cookies are necessary to ensure basic functions of the website. For example, these cookies are needed when a user adds a product to the shopping cart, then continues surfing on other pages and only goes to checkout later. These cookies do not delete the shopping cart, even if the user closes his browser window.
These cookies collect information about user behavior and whether the user receives any error messages. These cookies are also used to measure the loading time and the behavior of the website in different browsers.
These cookies ensure a better user experience. For example, entered locations, font sizes or form data are stored.
These cookies are also called targeting cookies. They are used to deliver customized advertising to the user. This can be very practical, but also very annoying.
Usually the first time you visit a website, you will be asked which of these types of cookies you want to allow. And of course this decision is also stored in a cookie.
How can I delete cookies?
If you want to find out which cookies are stored in your browser, if you want to change or delete cookie settings, you can find this in your browser settings:
If you do not wish to receive cookies, you can set your browser to notify you whenever a cookie is set. In this way, you can decide for each individual cookie whether or not you wish to accept it. The procedure varies depending on the browser. The best thing to do is to look for the instructions in Google with the search term “Delete cookies Chrome” or “Deactivate cookies Chrome” in case of a Chrome browser or replace the word “Chrome” with the name of your browser, e.g. Edge, Firefox, Safari.
What about my privacy?
Since 2009 there are the so-called “cookie guidelines”. This states that the storage of cookies requires your consent. Within the EU countries, however, there are still very different reactions to these guidelines. In Germany, the cookie guidelines have not been implemented as national law. Instead, the implementation of this guideline was largely carried out in § 15, 3 of the Telemediengesetz (TMG).
If you want to know more about cookies and are not afraid of technical documentation, we recommend https://tools.ietf.org/html/rfc6265, the Request for Comments of the Internet Engineering Task Force (IETF) called “HTTP State Management Mechanism”.
