Are you wondering whether or not you have to notify your project to the Norwegian Center for Research Data (NSD)?
Surveyxact does not store IP addresses from respondents. You do not have to notify your project as long as you have a) activated an anonymous survey and b) do not store or collect personal data / personally identifiable information.
The person responsible for the survey must decide if NSD has to be notified or not. Take a test, read more about what is considered to be personal data and your obligations in relation to your survey at NSD.
