Data Protection

The Federal Institute of Hydrology and/or IHP/HWRP take the protection of personal data very seriously. Our technology and organisation ensures that data protection regulations are observed by ourselves and by external service providers.

You may basically use our internet presence without disclosing your identity. Where the internet presence offers the option of entering personal or business data (e-mail addresses, names, postal addresses), these data are disclosed by the user on an explicitly voluntary basis. Using and paying all services offered is also possible without entering such data or by entering anonymised data or an alias – as far as technically feasible and reasonable.

In connection with your accessing our homepage, data will be stored for backup purposes. These data might allow identification (e.g. IP-address, date, time and pages viewed). The IP address will not be used to identify the user. Furthermore, neither personal data nor pseudonymised user profiles will be compiled. The right to statistically evaluating anonymised datasets shall be reserved.

In the event of your placing an order, we only use your personal information within the Federal Institute of Hydrology and/or IHP/HWRP and at the company commissioned to dispatch the brochures. We will not pass on the data to any third parties without your express consent. To the extent to which we are bound by law or by court ruling to do so, we will transmit your data to such authorities entitled to request information.
