In short, yes. When your report is processed, we convert your CSV into temporary database tables which are used to generate your report. As soon as your report generation is complete, these temporary tables and your order CSV file are permanently deleted from our systems. However, if you wish to anonymise all customer data contained in the report, there is an option to do this at the project level during the project creation process. This will not affect the other data generated in the report in any way.
