Anonymizing Data After Survey Completion

Learn how to anonymize data after your survey has been completed

This method may be particularly useful when you want to work with your survey data, but not in a manner which identifies your respondents.

Snap Survey Software stores respondent data in a file with the survey name and extension .rdf (respondent data file), and replies for each respondent are held in individual records in that file. When you delete the variable that holds the personal information from the survey file (.mdf), the details remain in the data file. It is possible to remove the personal data entirely.

We’ve create a helpful worksheet to walk you through the following steps:

  1. Back-up the survey
  2. Use the bulk change feature
  3. Check the data to ensure your changes are correct
  4. Delete the back-up

This worksheet is part of our GDPR (General Data Protection Regulation) series of worksheets. The GDPR applies only to personal data. The obligations under the GDPR do not apply to anonymous data. We offer several options to anonymize your surveys, including the option to run anonymous surveys using Snap WebHost.
