How do I delete my database in a Sandbox app?

I would like to delete all data (and memory of users/single sign on users) from my Sandbox Application, is this possible or should I completely create a new project and just deploy it from there? The main reason I'm asking this is that I modified the single sign on microflow so that it also creates an account in my HRM module, so that it associates your mendix login with a ''user account/employee account'' in my application. However this does not work for any user who has previously logged in into the application as they allready have a User Identity

I think the easiest solution is to add a retrieve and delete activity for users in your startup microflow, deploy it once, and then remove this functionality again.
