Data Protection

Data protection statement

This data protection statement is valid for all websites operated by the Deutscher Wetterdienst (DWD). The DWD takes the protection of your personal data very seriously. We want you to know when we gather personal data from you, which data is being collected and how we use it. We strictly adhere to the legal provisions of the German Federal Data Protection Act (BDSG) which regulates the processing and use of personal information. In the course of the further development of our websites and the implementation of new legal provisions or technologies introduced to improve our services to you, it might become necessary to amend or modify this data protection statement. We therefore recommend that you reread this data protection statement from time to time.

Access to the internet services

During every access to the GRUAN websites, a certain amount of data is stored in a log file for statistical and security purposes. We only log the following data for a limited period of time:

  • name of the file requested
  • date and time of the access
  • volume of data transmitted
  • information on whether the access was successful
  • browser, browser version and operating system
  • the address of the web page you were on when you called up our pages (so-called HTTP referer, if available)
  • anonymised IP address of requesting host (last two bytes are set to 0, e.g.

This data is used exclusively for improving our internet services and any way of tracing the data back to you is excluded.

Information logged during the access to GRUAN websites is only passed to third parties where disclosure is required by law or by court decisions or is necessary for the purposes of law enforcement or criminal prosecution in case of attacks on the infrastructure of the GRUAN's web presence. We do not pass on any personal information – neither for commercial use nor for any other non-commercial purpose.


When you order information or subscribe online to one of the GRUAN newsletters or services, we will ask for your name and other personal details. This is done for the purpose of processing your enquiries and orders. You are free to decide whether you wish to provide this data or not. If you wish to receive the material ordered, though, it is imperative that you provide the information requested.

You may, at any time, object to the storage of your personal details. If you do so, any stored personal details of yours will be deleted completely. Please note that in such case we will not be able to proceed with your order.

Use of cookies

Certain pages use cookies without us having the opportunity to inform you. Most browsers are set to accept cookies automatically. You have the option, though, of disabling cookies or setting your browser so that cookies are stored temporarily for the duration of the internet session only.

Protection of minors

Persons under the age of 18 should not submit any personal information to us without the consent of their parents or legal guardian. We do not ask children or youngsters for personal information. We do not gather such data knowingly and do not pass it on the third parties.

Links to third-party websites

Our online offer contains links to third-party websites. We have no influence on whether these providers comply with data protection rules and regulations.

This GRUAN website is managed by DWD. Because of that the original data protection page on is binding.
