Included in the plan is storage for 90 days of data. After the 90 days, the data will be erased. You do have the option of exporting data to reports and saving the reports. If longer storage is needed, we have storage plans available for up to 100 months. The first 90 days will always be free, only the additional storage requirements will be billed. Price varies depending on how much storage is needed. Please contact us for a quote.
