Personally Identifiable Information (PII)

Personally identifiable information (PII) is any data that can identify a specific person — a name, email, phone number, address, or account ID. It's the category that data privacy regulation is most concerned with.

Knowing what counts as PII shapes how you build forms, what your analytics may record, and how you store and protect data behind authentication. The safe habit is to collect only what you genuinely need and guard what you keep.
