Regulator And AuthorityGreen
The Connecticut Attorney General has exclusive statutory authority to enforce the CTDPA; there is no dedicated state privacy agency (unlike California's CPPA).
Claims (1):
- The Connecticut Attorney General has exclusive authority to enforce violations of the CTDPA and there is no private right of action.
Act And InstrumentsAmber
Core instrument is the CTDPA as amended by the Online Privacy Act (2023), the 2024 minors' amendments, the 2025/2026 threshold-lowering amendments (effective July 1, 2026), and Public Act 26-64 (SB4, effective October 1, 2026) adding data-broker and facial-recognition provisions.
Claims (3):
- Governor Ned Lamont signed Senate Bill 6 (the CTDPA) into law on May 10, 2022, and the Act took effect on July 1, 2023.
- Amendments to the CTDPA going into effect on July 1, 2026 broaden applicability thresholds, including making all sensitive-data processing and all sales of personal data covered under the law.
- Public Act No. 26-64 (Senate Bill 4), signed May 27, 2026, amends the CTDPA and establishes a data-broker registration and deletion-request framework, with key provisions (data brokers, facial recognition technology, precise geolocation) taking effect October 1, 2026.
Material ScopeGreen
CTDPA covers personal data of CT residents acting in an individual/household context; excludes employment-context data and 16 categories of exempted data overlapping with federal sectoral laws (HIPAA, FCRA, GLBA, DPPA, FERPA, Farm Credit Act, Airline Deregulation Act).
Claims (2):
- The CTDPA protects a Connecticut resident acting in an individual or household context but does not protect an individual acting in an employment context.
- The CTDPA contains 16 categories of exempted data, including specific information regulated by HIPAA, the Fair Credit Reporting Act, the Driver's Privacy Protection Act, FERPA, the Farm Credit Act, and the Airline Deregulation Act, plus exemptions for specific employee and job-applicant data.
Territorial ScopeGreen
Applies to persons conducting business in Connecticut or targeting products/services to CT residents meeting the statutory thresholds; no extraterritorial reach beyond that consumer-targeting test.
Claims (1):
- The CTDPA protects a Connecticut resident acting in an individual or household context but does not protect an individual acting in an employment context.
Regulator Registration And FilingAmber
The CTDPA itself imposes no general controller registration/filing requirement; however, Public Act 26-64 (effective Oct 1, 2026) newly requires data brokers to register and establish a deletion mechanism.
Claims (1):
- Public Act No. 26-64 (Senate Bill 4), signed May 27, 2026, amends the CTDPA and establishes a data-broker registration and deletion-request framework, with key provisions (data brokers, facial recognition technology, precise geolocation) taking effect October 1, 2026.

Regulator & Framework
The Connecticut Attorney General remains the sole enforcement authority for the CTDPA; the state has no dedicated data-protection agency. Effective July 1, 2026, the Act's consumer-volume applicability threshold was lowered from 100,000 to 35,000, with new triggers requiring no minimum volume at all where a business processes sensitive data or sells personal data -- a change that pulls a materially larger population of Connecticut businesses into scope. Separately, Public Act 26-64 (SB 4), signed by Governor Ned Lamont on May 27, 2026 and subsequently amended by HB 5222 and HB 5563, establishes a new data-broker registration program requiring brokers to register beginning January 1, 2027, alongside further CTDPA amendments taking effect October 1, 2026.
Taken together, these two enactments represent the most substantial widening of Connecticut's data-protection architecture since the base Act took effect in 2022. The lowered threshold in particular changes who must comply, not merely what compliant businesses must do, which is a structurally significant shift for mid-sized businesses previously outside the Act's reach.
Outlook
The data-broker registration program opens January 1, 2027, and the further PA 26-64 amendments take effect October 1, 2026 -- both dates businesses should track closely. Primary statutory text for PA 26-64 was not directly retrieved this cycle, and whether the Attorney General has issued or plans to issue CTDPA-specific rulemaking beyond the statute itself remains unestablished.
