In general, it is personal data that is included in data privacy. However, the exact definition of what that includes varies somewhat depending on the regulation.
The GDPR defines information that is protected as “personal data”, which is any information relating to an identified or identifiable natural person, including:
One or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of a natural person.
The CCPA defines information that is protected as “personal information”, which identifies, relates to, describes, is capable of being associated with, or may reasonably be linked, directly or indirectly, with a particular consumer or household. This can include such specifics as physically identifiable traits, online activity or geolocation.
