Keep sensitive data safe
Updated Jun 24, 2026
SheetApps protects sensitive fields like SSN and credit-card numbers.
Masking
- SSN and card fields show only the last 4 digits in the grid and forms, with a reveal toggle while editing.
- Any field can get the same treatment with a sensitive rule in your Rules sheet.
How to create a sensitive data field?
- In the Rules_ sheet assign value "sensitive" in the Rule Type column for the field in the form.
- Example: I want to make the field "Driver License" a sensitive field in my form. In this case, in the Rules_ sheet I will assign Rule Type "sensitive" to this field.
Storage
- Card numbers are only ever stored as the last 4 digits.
- With field encryption enabled, sensitive values are encrypted at rest in the database.
Exports
- Exports mask these fields by default; an owner can tick Include sensitive data to export real values where allowed.
Good to know
- Operator support access to your workspace is consent-based and read-only, and sensitive values stay masked in support views.
