RPR saves each report a user generates for 30 days. During that time period, the report appears in the reports sidebar on the left side of the Reports page and also can be accessed from a link in the email you receive when the report is generated. After a month, the report is no longer available and cannot be identically regenerated because the underlying data have changed. A report is a unique snapshot of a property or an area at a given time.
RPR recommends downloading and saving any report that is particularly important to you.
