Privacy by Design
An approach that embeds data protection and privacy considerations into the design and architecture of systems and processes from the start, rather than adding them as afterthoughts.
Why privacy by design matters
Privacy by Design is a requirement under GDPR and a best practice globally. It means considering privacy implications at every stage of product development - from choosing what to track to how data flows through your systems.
For analytics teams, this means building your tracking plan with privacy in mind: starting with the minimum necessary data, securing transmission and storage, and providing easy consent and deletion mechanisms.
