Hello,

for my survey I need to use the geographical data of the respondents' work and home locations to calculate the distance between these points. I use the short text map question type to inquire the coordinates of these locations. This also means that the coordinates will be saved in the results. However, I want to be able to guarantee that the survey does not save sensitive information, so that the respondent remains anonymous. Is there a way to save the coordinates for the duration of the survey and discard them once the survey is completed?

Thanks for your help

You can create a plugin to delete some values when survey is submitted
manual.limesurvey.org/AfterSurveyComplete is the event to use


@Joffm solution is better

Hi,
try to create a question of type equation at the end of the survey which sets these fields to "" (blank).
I assume your geo question is a question of type "short text". Let's have it the code "geo1".

So your equation wold be {geo1=""}




But the answer table has no data.

Joffm's approach is an elegant solution but I think another concern will be convincing respondents that you only want to "temporarily" use the location data.

Thank you so much, Joffm! This is exactly what I needed.

@tpartner I agree. Convincing the respondents that I only use the data within the survey is tricky. However, I do not save the locational data in the results, so I can claim with good conscience that their answers will be anonymous. Whether the respondent chooses to believe my claim is ultimately up to them.
