I’ve seen how the definition can really stretch beyond names and emails to things like IP addresses, device IDs, even cookies that can track behavior over time. In some cases, seemingly anonymous data can be linked up to reveal personal information. There have been interesting GDPR cases where minor metadata was deemed personal data. It’s a reminder that whenever data is collected—even if indirectly—there’s a potential privacy risk, so it’s worth thinking through how that data might be used or combined with other info down the line.
