Whenever you access a website, your computer must identify to the server which is asked to provide the requested site. The server must "know" to whom to send the answer. So when calling up a website, your pc sends a sender address to the server. This "sender" is the IP address assigned to each single computer in the worldwide web. It is a number combination and may look like this:

The university server also has an IP address:

When you enter a destination in your browser, such as as a combination of letters, this is internally converted into the respective IP address, since computers communicate better via numbers . 

On each access to a UW/H website, the IP address assigned to your pc is registered and saved in a logging file. 

These data help us to improve our web services and identify system errors. IP addresses are counted for statistical purposes (e.g. analysis of frequency and distribution). 

No inference is made about your person. The IP address is an anonymous code figure and does not permit to determine your identity. 

As a matter of principle we do not collect personal data (like names or e-mail addresses) via UW/H websites, unless you make such data available to us by choice (e.g. in applications) or give your consent, or legal privacy regulations explicitly permit to do so. 

In no case are IP addresses linked to other data you may have entered, e.g. on forms on UW/H websites.

Facebook privacy notice

Our website uses so-called social plugins (in the following called plugins) of the social network operated by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA (in the following called Facebook). Facebook marks plugins with a facebook logo and/or the addition "Facebook Social Plugin".

Various pages on our website contain such plugins which directly connect to the Facebook servers on access. If a user interacts with one of these plugins ("like", "recommendation", "comment" etc.) Facebook is able to record and analyse access to certain websites. Your IP address for example and - if you are registered with and logged in - your user name may be transmitted to Facebook. Ths means Facebook can link access to a website with your personal data and thus identify you, which may also mean collection of personal data.

See the Facebook privacy notice (Datenschutzhinweisen von Facebook) to determine the exact purpose and scope of data collection via Facebook, handling and use of such data, and your rights and setting options to ensure privacy. If you are registered with Facebook and do not want Facebook to collect data related to you via plugins, you must log out on facebook. com prior to accessing UW/H websites. 

PIWIK privacy notice

Our website uses the open source software PIWIK for statistical usage evaluation. The collected data enable us to further optimise our services and make our website easier to use. Data collected via PIWIK (for example, abbreviated IP address, date and time, accessed website, browser, search engine) are saved in an internal databank on our server. PIWIK based evaluations of usage are completely anonymized, cannot be used to identify individuals, and are not transmitted to third parties, nor are stored data linked up.
