The World's De Facto Privacy Law

GDPR took effect May 25, 2018, regulating personal data of EU residents regardless of where a company is based. Because few large companies can afford to carve out Europe, GDPR effectively became a global standard. California's CCPA, Brazil's LGPD, and India's DPDP Act are all heavily GDPR-inspired.

The six core principles

Lawfulness, fairness, transparency — you need a lawful basis to process data
Purpose limitation — collect for a specific purpose, do not quietly repurpose
Data minimization — only what you need
Accuracy — keep data correct and up to date
Storage limitation — delete data when no longer needed
Integrity and confidentiality — secure the data

What counts as personal data?

Individual rights

Right to access — see what data is held about you
Right to rectification — correct wrong data
Right to erasure (right to be forgotten) — delete your data
Right to data portability — get your data in a portable format
Right to object to processing (including automated decision-making)
Right to withdraw consent

GDPR and AI training

A person can theoretically request deletion of their data from a trained model. Models, however, do not store individual training examples cleanly, making true deletion hard. In 2023, Italy briefly banned ChatGPT over GDPR concerns. OpenAI responded with data controls and opt-outs. This remains a live legal tension.

Practical compliance steps

Maintain a record of processing activities (Article 30)
Establish a lawful basis before collecting data
Write clear privacy notices
Implement processes for data-subject rights requests
Conduct a Data Protection Impact Assessment (DPIA) for high-risk use
Report breaches within 72 hours

The big idea: GDPR made privacy a user right rather than a corporate favor. AI builders must design with these rights from the start, not bolt them on later.
