What Is the Connecticut Data Privacy Act?

CTDPA covers controllers processing personal data of 100,000+ Connecticut consumers or 25,000+ while selling data. It grants access, deletion, correction, portability, and opt-out rights. Connecticut recognizes universal opt-out mechanisms (GPC) as legally binding. Enforcement is exclusively by the AG. The 60-day cure period sunset on January 1, 2025.

Who CTDPA applies to

A business is covered if it meets the applicability thresholds set out in Conn. Gen. Stat. § 42-515 et seq.. Most state laws use an “or” framework — any one of the thresholds triggers coverage unless otherwise noted.

  • Controls or processes personal data of 100,000+ Connecticut consumers (excluding data processed solely for completing a payment transaction), OR
  • Controls or processes personal data of 25,000+ Connecticut consumers AND derives over 25% of gross revenue from the sale of personal data

Consumer rights under CTDPA

Right to deletion, access, correction, portability

Right to opt-out via GPC universal opt-out

AG exclusive enforcement

Notable features (vs. CCPA)

CTDPA requires businesses to honor Global Privacy Control (GPC) as a valid opt-out signal — a stronger default than CCPA at the time of enactment. Connecticut added protections for teens (13-16) requiring opt-in for targeted advertising and sale, and enhanced consumer health data provisions through a 2023 amendment. Connecticut also requires businesses to recognize authorized agent requests.
