We only collect data from surveys that our completed by the enduser.
Almost all the data we collect in our surveys, is in no way traceable to a specific person. There are exceptions for open questions or direct questions such as 'What is your name?'. Users can fill our open questions with specific data that makes the user known in the system.
Do you want to use questions to gather personal data? Then please contact us on firstname.lastname@example.org and we will provide you with solutions.
