Terms of Use

LimeSurvey is an open source tool hosted by IT-SERVICES "as is". Please note, that the source code of LimeSurvey has not been subjected to any in-depth security audit. Usually, for a normal collection of empirical data this is not necessary, as personal or sensitive data are not in focus.

LimeSurvey must not be used for the systematic collection of personal data or for the collection of sensitive or highly sensitive data. Also, it is necessary to clarify up front whether may be collected at all. In case of doubt, consult with the Legal Department of WU. This also applies if data from third parties should or has to be used to carry out the survey.
