Delaware Privacy Law Overview

Delaware's privacy law took effect January 1, 2025. With thresholds as low as 35,000 consumers and few of the blanket exemptions found in other states, it reaches a wide range of organizations, including many nonprofits and smaller businesses that serve Delaware residents.

The Delaware Personal Data Privacy Act (DPDPA)

Delaware's law provides comprehensive consumer rights with opt-in consent for sensitive data and recognition of universal opt-out signals from January 1, 2026. Its low thresholds and narrow exemptions — including coverage of many nonprofits — make it one of the broader-reaching state privacy laws despite Delaware's small population.

DPDPA: Quick Overview

  • Effective Date: January 1, 2025
  • Citation: Del. Code tit. 6, ch. 12D
  • Enforced By: Delaware Department of Justice
  • Maximum Penalty: Up to $10,000 per violation
  • Private Right of Action: No (enforcement by the state only)
  • Right to Cure: 60 days (expired December 31, 2025)

Who Must Comply

The DPDPA applies to businesses that meet Delaware's applicability thresholds:

  • Controls or processes the personal data of 35,000+ Delaware consumers per year, or
  • Processes data of 10,000+ consumers and derives more than 20% of gross revenue from selling personal data

What makes Delaware different: Low thresholds and few exemptions — including coverage of many nonprofits — give Delaware's law unusually broad reach.

Consumer Rights Under the DPDPA

Delaware residents can exercise the following rights over their personal data:

  • Right to access / confirm what data is held
  • Right to correct inaccurate data
  • Right to delete personal data
  • Right to data portability
  • Right to opt out of targeted advertising
  • Right to opt out of the sale of personal data

Data Breach Notification in Delaware

Delaware requires notice to affected residents within 60 days and to the Department of Justice when a breach affects more than 500 residents.

Delaware Privacy Law FAQ

Why does Delaware's privacy law reach so many businesses?
Delaware set low thresholds (35,000 consumers, or 10,000 with data-sale revenue) and declined to adopt many of the broad exemptions seen elsewhere, including for nonprofits. As a result, a relatively wide range of organizations serving Delaware residents must comply.
Who enforces the Delaware Personal Data Privacy Act?
The Delaware Department of Justice enforces the law and may seek civil penalties of up to $10,000 per violation. The 60-day cure period expired on December 31, 2025.
