App creators may designate specific columns as containing personally identifiable information (PII), and indicate that AppSheet should not retain any information about those columns in the system logs.
Once correctly configured, if you update a record with a PII column, AppSheet's system logs would not record those columns. They simply get passed along to the back-end source of data.
To mark a column as PII, set the Sensitive data toggle in the column definition dialog to "ON", as shown below:
Once enabled, content from columns containing 'Sensitive Data' will no longer be logged in the app audit history, instead writing the value '_PII_' to the cell.
Note: We recommend you evaluate all of the safeguards and features that the AppSheet platform includes in order to decide if these features meet your compliance criteria.
