Question
How does it it possible that it runs in the background, without an external server/service?
Answer
The short answer is M-A-G-I-C. All kidding aside, we created a smart algorithm that schedules the task in the background of one or more the admins. That means the process will be running and scheduled as long as a person with a role Administrator is logged in to Zendesk.
We purposely choose to solve it this way, so it's easier for you to be GDPR compliant because there is no need for external servers.
