Hi Nikola,
Thanks for the reply. I had not noticed the new manual 6-month deletion feature and so I have updated my review accordingly.
While it is a welcome addition to what is a good plugin, I think you would do well to introduce automated deletion of clients data and easier bulk deletion of data on the Appointments page, rather than a button hidden in the customise/settings area.
As I said, busy administrators could easily be storing the personal contact details of thousands of clients when they don’t even know it is still in the database.
Hope that helps!
Thanks,
Chris
