Web Analytics with "Piwik"
Leibniz Universität Hannover uses the open-source software Piwik as a web analytics platform. The software developers are in close contact with the Independent Regional Centre for Data Protection Schleswig-Holstein (ULD).This means that they implement data protection rules and regulations so that Piwik can be used in accordance with German jurisdiction, in compliance with data protection laws and in a legally secure way.
Your IP address is made anonymous immediately after processing and before storing it. Piwik has been configured according to the recommendations of the Independent Regional Centre for Data Protection Schleswig-Holstein (ULD) and complies with current data protection regulations.
By using these internet services you declare that you agree to the processing of data collected about you as described above and solely for the above-mentioned purpose.
Piwik endorses the “Do Not Track“ method of current web browsers. If you wish to generally prohibit any analysis of your web behaviour, we recommend that you activate this option in your browser. Alternatively, you can prohibit Piwik web analysis on websites in the uni-hannover.de network area by using the following button.
Sharing in social media such as Facebook, Google+ und Twitter
Some of the Leibniz Universität Hannover web presence offers the opportunity to share individual pages in social networks by means of share buttons. Via these plugins, data (including personal data) can reach external providers such as Facebook, Google and Twitter and be used by them.
Leibniz Universität Hannover does not itself use social media plugins to gather personal data or information on its use. To prevent data reaching network providers without the active participation of the user, Leibniz Universität uses the data-friendly "sheriff solution" in its web presence (for further information visit: http://m.heise.de/ct/artikel/Shariff-Social-Media-Buttons-mit-Datenschutz-2467514.html).
With this technology, a direct link between user and external social media comes about only when the user actively clicks on one of these buttons. Only then can data be transferred to the external provider and stored there.
The external provider then receives information that the corresponding subpage of our online presence has been accessed. For this the user needs neither to have an account with the external provider nor to be logged in there. If the user has logged in with the external provider, this data is directly assigned to the user account with the external provider. If one of our pages is shared, the external provider also usually stores this information in the user account.
Leibniz Universität Hannover has no influence on whether, to what extent, for how long and to what purpose external providers gather personal data. We can however assume that at least the IP address and device-related information are collected and used. Further information on the handling of data protection on social media platforms can be seen on their websites:

b) Google Inc., 1600 Amphitheater Parkway, Mountainview, California 94043, USA
c) Twitter Inc., 1355 Market St, Suite 900, San Francisco, California 94103, USA
d) WhatsApp Inc, 650 Castro Street, Suite 120-219, Mountain View, California, 94041; USA
Entering Data Into Forms on Leibniz Universität Websites
Where internet services allow for the entry of personal or business data (E-mail addresses, names, addresses), disclosing this data is on an expressly voluntary basis on the part of the user. Using and paying for all services offered is - as far as this is technically possible and reasonable - granted also without disclosure of such data or through the use of anonymised data or a pseudonym. The use by third parties of contact data published in the imprint or similar, such as postal addresses, telephone and fax numbers and e-mail addresses, for transmitting not specifically requested information is not allowed. We expressly reserve the right to take legal steps against the senders of so-called spam mails which violate this prohibition.
