As a sibling comment said, the notion is "Personal Data".
It is very wide and email address definitely fall within it. Also note IP is personal data, and an identifier like a UUID of the IDFA is personal data. The key point is that it must be related to an identified *or identifiable* data subject, ie even if that information is not enough to identify the person, the fact that it can contribute to it makes it personal data.
