PII
Also said as
personally identifiable informationpersonal data
PII — personally identifiable information — is any data that identifies a specific person: name, email, phone number, customer record, tax ID.
Why it matters to your business
Feed customer PII into a consumer AI tool and it may be retained, reviewed by staff, or used for training — creating obligations most owners never knowingly signed up for.
The catch · what vendors don't say
PII rules don't just bind the vendor — once you paste a customer's details into the wrong tool, the exposure is yours.
