Is there a limit to the amount of storage for EMRs allowed by TherapyCharts per provider over time?

From TherapyCharts

There is no limit on the number of patients, progress notes, treatment plans, etc that can be created. Within the document manager, which allows one to upload scanned documents, there are some limits to the amount of default storage you can use, but you can always buy more space to accommodate your needs if the defaults are not enough.
