Any data point can be used to de-anonymize you, but only with other data points, and with non-pii data only when cross referenced with large volumes of other data.
This is why surveillance capitalism is so draconian and dangerous. You only need DOB and postcode to accurately ID like 70% of the entire human population. But your PII is irrelevant in the grand scheme of things. The important data is the data that can be used to target and manipulate you. Your name and DOB are unimportant. Your gender and age group are what’s inferred from that data, and what’s important in conducting an affinity analysis.
If you order something ultra specific and it’s associated with your identity, that’s only useful the next time you order that ultra specific thing AND either instance is associated with your identity.
