Privacy Policy is a service offered by Hadley. All personal data are treated with the utmost care at Hadley. All the necessary steps are taken to guarantee the security of these data. This privacy statement supplements the General Terms and Conditions of Hadley. Please write to [email protected] if you have any questions or concerns relating to this document.

  1. Which data are stored?
    1. When you register with us, we record and save your basic data such as name and email address together with other contact information such as your password. We may receive further information from you via the website (e.g. if you fill in your personal profile) or if you communicate with us.
    2. Cookies

      After you have logged in (with email and password), uses cookies with which you can be identified for the duration of your visit. Cookies are also used generally on the website, e.g. to remember your text preferences. Cookies are small files stored on your computer or mobile device which identify the device to our server and also provide additional data. Other technologies such as pixel tags, web bugs, web storage and similar files fulfill the same purpose. A cookie is saved on your computer.

      One type of cookie automatically expires after your session has ended. This is called a session cookie. Your user settings, in particular, are saved as session cookies so that Hadley can always be used in the form you require. Another permanently stored anonymous cookie contains the version number of your Flash player. When you log in, you also have the option of saving your password locally in encrypted form on your computer. You can save this cookie permanently for automatic log in with the function "Log me in automatically on this computer". In addition to this, user settings, such as language selection, language recognition settings, user IDs for various applications, are saved in both session cookies and permanent cookies by Hadley in order to facilitate the use of Hadley.

      You can switch off the use of cookies for our website or in general in the settings of your Internet browser. You can find out how from the website of your Internet browser supplier. For Internet Explorer you can find the relevant instructions at, for Firefox at, for Apple Safari at and for Google Chrome at However, deactivating cookies will mean that a number of functionalities, e.g. automatically logging in to the website, will no longer operate as intended. However, deactivating cookies will mean that a number of functionalities, e.g. automatically logging in to the website, will no longer operate as intended.

      We may use the services of third parties to collect and use anonymous information about your visits to and interactions with our website through the use of technologies such as cookies to personalize advertisements for goods and services.

    3. Log files

      Each time a page is called up, access data are saved in a protocol file, the server log. The data record thus saved contains the following data:

      • your IP address (by means of which your computer can be unambiguously identified)
      • the remote host (name and IP address of the computer requesting the page)
      • the time, the status, the quantity of data transferred and the Internet page from which you accessed the requested page (referrer)
      • the product and version information of the browser used (user agent)

      Hadley uses a standardized webserver logfile format for this purpose. Provided these data are not urgently required for the technical maintenance of the system or for the system security, they are anonymized instantly and the original protocols are deleted. Anonymization takes place by removal or truncation of the IP address by allocating a code not assigned to a user. Any allocation to an identified or identifiable person is therefore no longer possible. Hadley therefore uses the protocol data (logs) exclusively in anonymized form for statistical evaluations, hence without any allocation or references to your personal details. In this way, Hadley determines, for instance, on which days and at which times is particularly popular and what volume of data is generated on the Hadley web servers. Furthermore, Hadley can detect possible errors through the log files, e.g. faulty links or program errors, and thus use the log files for the ongoing development and refinement of Hadley does not link the page requests and usage information to individual persons.

    4. Google Analytics

      This website uses Google Analytics, a web analytics service provided by Google, Inc. ("Google"). Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyze how you use the site. As anonymization is activated for the data we collect, your IP address is truncated by Google within member states of the European Union or in other signatory countries to the Treaty creating the European Economic Area and only then is it transferred to the USA.

      Only in exceptional cases will the full IP address be transferred to a Google server in the USA and truncated there. On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website in order to compile reports on website activity for the website operator and to provide other services relating to website activity and Internet usage. The IP address transferred by your browser within the scope of Google Analytics will not be combined with other data from Google. You may prevent the saving of cookies by selecting the appropriate settings on your browser; however, please note that if you do this, you may not be able to use the full functionality of this website. Furthermore, you can prevent the data captured by the cookie and relating to your use of the website (incl. your IP address) from being captured and processed by Google by downloading and installing the browser plugin available at the following link:

      Further information on the use of the data and privacy policy at Google Analytics is available at or Hadley uses Google Analytics exclusively in connection with the gat._anonymizeIp(); extension so that IP addresses are only recorded in truncated, i.e. anonymized form.

    5. Social Plugins

      In some cases, we use social plugins, incorporated from Facebook and Twitter on our website. This is done using a technology supplied by "ShareIt".

      Facebook Social Plugin

      Social plugins ("plugins") from the social network ("Facebook") are used on our website. Facebook is run by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304 in USA.

      If you call up a page on our website containing such a plugin, your browser will establish a direct connection with Facebook’s servers. The contents of the plugin are transferred by Facebook directly to your browser which incorporates it in the website. By incorporating the plugin, Facebook receives the information that you have called up the relevant page on our website. If you logged into Facebook, it can match your visit to your Facebook account.

      The purpose of capturing data and the quantity of data collected including the way in which they are processed and used by Facebook and your rights in this regard and setting options to protect your privacy can be taken from Facebook’s data protection information at: If you are a member of Facebook and you do not wish Facebook to collect data on you through our website and link them to your membership data stored by Facebook, you must log out of Facebook before visiting our website.

      It is also possible to block Facebook social plugins through add-ons for your browser, e.g. through "Facebook Blocker".

      Use of the Twitter widget

      We also use so-called "widgets" from Twitter on our websites. When these web pages are called up, a connection is established with Twitter servers. The Twitter servers are in USA.

      When a web page is called up containing a Twitter "widget", Twitter receives information that you have called up the page. The information includes your IP address, the type of browser, the operating system and the address of the website where the Twitter widget is located. The Twitter widget also installs a cookie in the browser of your terminal. In connection with the cookie, Twitter can theoretically see which other pages you have visited if there are Twitter widgets implemented on these pages too. Twitter itself states that it may also use these data - if you have a Twitter account - to give you better suggestions on suitable users. According to Twitter, it begins to delete the data after a maximum of 10 days. The deletion itself is then to be completed after a further week at the latest. If you have a Twitter account, you may be able to make further settings on the use of your data in your user account settings.

      You will find further information in Twitter’s data protection notice which you can call up here:

    6. Further external suppliers

      We use further external service providers for the purpose of optimizing our services, carrying out advertising activities or for analyzing our website for errors and in terms of its performance. Such service providers may vary.

    7. Newsletter & emails

      We send you emails for a variety of reasons. These may include confirmations of an order or of a registration. However, communication may also concern information about our services, provided you have not revoked your consent for such usage. Any email messages we send are saved by us. We also record any email addresses to which a message could not be delivered in order to request an updated email address. Furthermore, in the case of our newsletter emails, we record (e.g. by means of a so-called "tracking pixel") whether an email is opened and which links in the email are clicked on; we do so to optimize our emails and tailor their design to meet your needs. We use these data to enable us to send newsletter contents to match your profile. If you wish to object to this use of your data, you can unsubscribe from our newsletters at any time.

    8. Hotjar

      Hotjar - Unlimited insights from your web and mobile sites

      We use Hotjar in order to better understand our users’ needs and to optimize this service and experience. Hotjar is a technology service that helps us better understand our users’ experience (e.g. how much time they spend on which pages, which links they choose to click, what users do and don’t like, etc.) and this enables us to build and maintain our service with user feedback. Hotjar uses cookies and other technologies to collect data on our users’ behavior and their devices. This includes a device's IP address (processed during your session and stored in a de-identified form), device screen size, device type (unique device identifiers), browser information, geographic location (country only), and the preferred language used to display our website. Hotjar stores this information on our behalf in a pseudonymized user profile. Hotjar is contractually forbidden to sell any of the data collected on our behalf. For further details, please see the ‘about Hotjar’ section of Hotjar’s support site.

  2. Purpose of storing the data

    The purpose of gathering, saving, processing and using the data is solely to facilitate, maintain and develop services. In particular, part of the ongoing development involves the use of anonymous statistics on the usage of the services. Movement profiles of individual users on the website are not created.

  3. No forwarding of data to third parties

    Hadley does not forward the personal data of its users to third parties unless the user has given his/her explicit consent or there is a legal requirement to forward the data. Personal details may also be passed on to third parties if this is legally permissible, and it is necessary to pass them on for the fulfillment of our contractual obligations towards our customers. In the case of payment processing, the data for processing the payment transaction are forwarded to the payment services provider if you do not supply the data directly. If you send your payment data directly to the payment services provider, we receive only very limited data. In such cases, we are merely informed whether or not the transaction relating to a specific transaction number has actually taken place. In such cases we do not receive your account data. If any third-party rights have been violated (in particular rights relating to copyright, trademarks, names and symbols) by the user, the user data will not be forwarded to the rights holder unless the latter conclusively demonstrates his/her claims to Hadley.

  4. Data security

    Hadley employs safety precautions to guarantee that your data are protected against loss, modification or misuse. To this end, Hadley works with constantly updated firewalls meeting the industry standard as well as other security systems. At the same time, the user should be aware of the fact that one hundred per cent protection against attacks cannot be guaranteed because of the continual appearance of new viruses and other means of attacking the protected data systems of Internet services. Hadley will instigate civil and criminal proceedings against any attack by hackers and the like and will inform the users of any cases in which their data have been compromised.

  5. Information, correction and deletion
    1. Right to information on stored data

      Every user has the right to obtain information from Hadley on the personal data that has been saved in relation to him/her. If the request for information is not conveyed to Hadley in writing, hence particularly in the case of enquiries by telephone or email, the user must provide a postal address to which the information can then be sent. In the request for information, the user must additionally provide the following details for identification purposes: first name and last name, and email address.

    2. Corrections

      If the user alters or corrects the details that he/she has provided and deletes old entries, the data previously entered by the user will be completely deleted automatically. An application for correction or deletion is not required. You can edit your personal data at any time. This notwithstanding, the user has the right at all times to demand the correction of any inaccurate data concerning him/her stored with Hadley. However, the easiest option is for users to correct any such entries themselves.

    3. Deletion of data

      Should the user demand any alteration, correction or deletion of his/her personal data, this may take place by email or letter. To ensure correct identification of the user, the request must at least contain the following details:

      • First name and last name
      • Email address

      Please note that due to caching systems, search engines, the interposition of proxy servers and the like, deleted data may continue to remain accessible even though they are no longer present within our systems.
