Overview

The CTDPA features two unique elements among US state privacy laws: a consent revocation mechanism for sensitive data, and a prohibition on selling children's data or using it for targeted advertising even with consent (2025 amendment). The cure period was eliminated January 2025.

What This Means for Your Website

  • GPC signals must be honored since January 2025
  • Sensitive data requires opt-in consent with a unique revocation mechanism
  • Sale of data from minors under 18 is prohibited even with consent
  • Children under 13 require parental consent
  • No cure period: the AG can take immediate enforcement action
  • An age-appropriate design code for children's online services takes effect in 2026

Key Requirements

The Connecticut AG enforces the CTDPA with penalties up to $5,000 per willful violation, plus potential actual and punitive damages. Consumer requests must be fulfilled within 45 days. The 2025 amendments significantly strengthened protections for children's data, with active investigations targeting messaging, gaming, and chatbot platforms.

Other North America Regulations

CPRACalifornia, United States
The CPRA is the most comprehensive US state privacy law with a dedicated enforcement agency (CPPA). Cross-context behavioral advertising via cookies constitutes sharing personal information, triggering opt-out obligations. GPC signals must be honored as valid opt-out requests.
CCPACalifornia, United States
The CCPA was the first comprehensive consumer privacy law in the United States, giving California residents the right to know what personal information businesses collect and to opt out of its sale. It established the opt-out consent model that most subsequent US state privacy laws adopted.
PIPEDACanada
Canada's federal private-sector privacy law based on 10 fair information principles. Requires express consent for sensitive data and implied consent for less sensitive data. OPC guidance addresses cookies and online behavioral advertising. The CPPA replacement bill died January 2025; a new bill is expected.
CIPACalifornia, United States
CIPA is a 1967 California chapter covering wiretapping, eavesdropping, and other privacy invasions, not a website-specific law. Since 2022, courts have applied two of its sections to website chat, analytics, and ad tools, and any visitor can sue directly for at least $5,000 per violation, no revenue threshold.
Quebec Law 25Quebec, Canada
Quebec's Law 25 is the strictest privacy law in Canada and the closest North American equivalent to the GDPR. Consent must be clear, free, informed and requested for each purpose, and any technology that identifies, locates or profiles a visitor has to be disclosed. Its privacy-by-default rule carves out browser cookie settings, but non-essential cookies still need consent first.
CPAColorado, United States
Colorado's CPA features the highest per-violation penalties among US state privacy laws at $20,000. Must honor GPC signals since July 2024. Participated in a joint GPC enforcement sweep with California and Connecticut in September 2025. The cure period was eliminated in January 2025.
