What is GDPR and Why It Matters

The General Data Protection Regulation (GDPR) is the EU's comprehensive data protection law that came into effect on May 25, 2018. It applies to any organization processing personal data of EU residents, regardless of where the company is located. With fines reaching up to 4% of annual global revenue, GDPR compliance is critical for any business with an online presence.

Contract Performance

Processing is necessary to fulfill a contract with the individual or to take pre-contractual steps at their request.

Vital Interests

Processing is necessary to protect someone's life. Rarely applies to website data processing.

Public Task

Processing is necessary for performing a task in the public interest or in the exercise of official authority.

Legitimate Interests

Processing is necessary for your legitimate interests, except where overridden by the individual's rights and freedoms.
