Automatic Deletion of Responses after x time

Hi peeps,

Looking at GDPR and user right towards their data we are thinking of a way to be able to keep the rights of the user's data at the user. We as a third person data collector want to be able to do the following and perhaps know if this is possible:

- Setup a cron job that automatically check all reponses by date. If they are older than 30 days. They get deleted. Possible and if so, how is the best way to set this up?

- After the user completed the survey, they get a thank you email for filling it out. No problem there, but is there a way to include a link where, if they choose to do so, let them delete their response.

If possible it would be custom coding for sure, but I'd like to hear if it is possible and if anyone has made something like this before.

Thanks in advance!

Perhaps this plugin can be improved:

Great input! Thanks We can use this for the emails for sure.
Now for the auto-deletion itself would be great.
And creating a plugin which covers a wide area of the GDPR law(s) would be beneficial for all user of Limesurvey.
