Report on # of emails sent doesn't show data older than 3 months

Oh, I didn’t know that setting affected the report as well. Was it an intentional choice? I may not want to store email logs (which include personal data: recipient email and username) indefinitely, but I’d like to keep the depersonalized number of emails sent on a given day.

I know I can request these reports periodically and store them locally, but maybe there’s a point in storing them on the server by default as well?
