For GDPR reasons I need to ensure contact details and survey responses cannot be linked so I've redirected respondents out of survey 1 to survey 2 so that they can input their contact details separately. However, I realised that the presence of date and time metadata will mean that technically it is possible to link the two survey responses. So I'd like to know if it's possible to stop Qualtrics from storing the date and time of data collection for one of the surveys. Thanks for your time.

In survey 1 itself you can anonymize the response by checking Anonymizing Responses in survey options.
