What is a customer data platform (CDP)? Your data, unified.
Customer data platforms explained: how tools like a CDP combine your data from many sources into one profile, and what that means for your privacy.
The simple answer
A customer data platform, or CDP, is a tool that gathers your data from many sources, website, app, email, support, purchases, and stitches it into one unified profile of you.
The benefit for companies is a single view of the customer. The privacy trade-off is that scattered bits of data become one detailed profile, which makes purpose, consent and security more important.

Scattered data becomes one profile.
State of Privacy cares about data unification because a single combined profile can reveal far more than any one source alone, which raises the stakes for consent and security.
