Data Collection

For statistical data collection purposes, the GWDG employs the web analytics tool Piwik. It is used by the central website www.gwdg.de.

The following instructions and settings are relevant for all websites utilising the central Piwik server.

Options to Object

You have the following independent option to object to the collection of data by the central Piwik server:

Activate your browser’s Do-Not-Track setting. As long as this setting is active, our central Piwik server will not store any data about you. Note: As a rule, the Do-Not-Track setting is only valid for the specific computer and the specific browser in which you activate this setting. Should you use more than one computer or browser, please make sure to activate the Do-Not-Track setting on all of them separately.
