Following the lead of California, Virginia, Colorado and, most recently, Utah, Connecticut has become the fifth state to pass comprehensive consumer data privacy legislation. The Connecticut legislature passed “An Act Concerning Personal Data Privacy and Online Monitoring” (referred to in this Legal Update as the “Connecticut Data Privacy Act” or “CTDPA”) on April 28, 2022. Connecticut Governor Ned Lamont signed the bill (SB 6) into law on May 10, 2022, and the CTDPA will take effect on July 1, 2023. Connecticut is the second state to enact such a law in in 2022, following in the footsteps of the Utah Consumer Privacy Act (“UCPA”), which was signed into law on March 24, 2022, and will take effect on December 31, 2023.

Companies that have followed the California Consumer Privacy Act (“CCPA”), the California Privacy Rights Act (“CPRA”), Virginia’s Consumer Data Protection Act (“VCDPA”), the Colorado Privacy Act (“CPA”) and the UCPA will find many similarities in the CTDPA. Similar to the other non-California laws, the CTDPA adopts the “controller” and “processor” nomenclature used in the EU General Data Protection Regulation (“GDPR”) and does not include a private right of action for consumers to sue for potential violations. Nor does the CTDPA extend consumer rights to the employee or business-tobusiness context. The CTDPA grants applicable consumers certain familiar rights, including to access, correct and delete their personal data.

The CTDPA is arguably less business-friendly and more consumer-oriented than the Virginia and Utah frameworks, aligning more closely with Colorado’s law and in some ways with the California model. Similar to Colorado, the CTDPA requires controllers, starting January 1, 2025, to recognize consumers’ opt-out preference signals for targeted advertising and sales, a mechanism often referred to as “global opt-out.” (In California, once the CPRA takes effect, businesses will have the option, but not the obligation, to recognize opt-out preference signals while Utah and Virginia have no global opt-out provisions.) The CTDPA does not require controllers to authenticate consumer opt-out requests; rather, controllers may deny opt-out requests if it is unreasonably burdensome to associate the request with the personal data. Like California and Colorado, the CTDPA grants consumers the right to opt-out of personal data sales, targeted advertising, and profiling, and the CTDPA’s definition of “sale” is similarly broad.1 Also, like California and Colorado, the CTDPA’s right for controllers to cure violations has an expiration date (December 31, 2024).

Notably, the CTDPA does not authorize the Connecticut Attorney General (“CT AG”) to engage in rulemaking, although future rulemaking from Colorado and California on similar provisions may May 11, 2022 2 Mayer Brown | Connecticut Passes Comprehensive Privacy Law: Comparing to Other State Privacy Laws May 11, 2022 influence the interpretation of such provisions in the CTDPA. Similar to Colorado and Virginia, the CTDPA requires opt-in consent for the collection and processing of “sensitive data”;2 however, the CTDPA also requires controllers to provide a mechanism for consumers to revoke this consent. Also, the CTDPA takes a hard line on children’s data, requiring controllers to obtain consent to sell the personal data of a consumer between the ages of 13 and 16 or to process that data for targeted advertising.


The CTDPA applies to for-profit entities that conduct business in Connecticut—or produce products or services targeted to Connecticut residents—and that in the preceding year controlled or processed3 the personal data of:

i. At least 100,000 Connecticut residents or

ii. At least 25,000 Connecticut residents and derived over 25 percent of gross revenue from selling personal data.

The CTDPA protects “consumers,” and covered businesses are referred to as “controllers” or “processors.”4 The CTDPA does not apply to personal data collected in an employment or business-to-business context. “Personal data” is defined as information “linked or reasonably linkable to an identified or identifiable individual” and does not include de-identified data or publicly available information. Covered entities are not required to re-identify de-identified or pseudonymous data in order to comply with the statute.


Like the other comprehensive state laws, the CTDPA contains exemptions. In addition to not applying to entities that do not meet the size threshold, the CTDPA’s obligations do not apply to state government agencies, covered entities and business associates regulated by the Health Insurance Portability and Accountability Act (“HIPAA”), financial institutions regulated by the Gramm-Leach-Bliley Act (“GLBA”), nonprofits and institutions of higher education. 

Data Subject Rights

The CTDPA provides consumers with rights relating to their personal data that consumers may request to exercise using methods established by the controller and described in the controller’s privacy notice. These rights include:

  • Confirmation that a controller is processing the consumer’s personal data and access to the consumer’s personal data unless such confirmation or access “would require the controller to reveal a trade secret”
  • Correction of inaccuracies in the consumer’s personal data
  • Deletion of the personal data provided by, or obtained about, the consumer
  • Data portability: the right to obtain a copy of the consumer’s personal data in a “portable” and “readily usable” format
  • Opt-out of the processing of the consumer’s personal data for purposes of (i) targeted advertising, (ii) sale or (iii) profiling in furtherance of automated decision-making 

Data Controller and Processor Obligations

Like the other non-California frameworks, the CTDPA adopts the “controller” and “processor” structure set forth in the GDPR. The CTDPA requires a processor to adhere to the controller’s instructions and assist the controller in meeting its obligations under the statute. The parties must enter into a binding contract that governs the processor’s data processing procedures on behalf of the controller. The contract must include:

  • Instructions for the processing
  • Nature and purpose of the processing
  • Type of data subject to processing 
  • Duration of the processing
  • Rights and obligations of both parties
  • Requirement that each person processing personal data is subject to a duty of confidentiality
  • Requirement for the processor to delete or return the personal data at the controller’s direction at the end of the provision of services 
  • Commitment to engage any subcontractors, after providing the controller an opportunity to object, via a written contract that requires the subcontractor to meet the obligations of the processor
  • Commitment to cooperate with reasonable data security assessments by the controller or a designated third party

In addition, the CTDPA requires controllers to conduct and document a data protection assessment for each processing activity “that presents a heightened risk of harm to a consumer.” Such processing activities include (i) processing for purposes of targeted advertising, (ii) sale of personal data, (iii) processing for purposes of profiling and (iv) processing of sensitive data. The CT AG may require that a controller disclose any data protection assessment relevant to a CT AG investigation. 

Effective Dates and Enforcement

The CTDPA adds to a growing timeline of comprehensive consumer privacy laws and regulations. The CCPA and its implementing regulations are already in effect. The CPRA becomes operative January 1, 2023, and enforceable on July 1, 2023, along with regulations to be adopted by the new California Privacy Protection Agency (“CPPA”). Draft CPRA regulations have been delayed until fall 2022. The Colorado AG also plans to issue draft regulations by fall 2022, to be finalized and adopted by July 1, 2023, when the CPA takes effect. The VCDPA (effective January 1, 2023) and UCPA (effective December 31, 2023) do not feature rulemaking or regulations. The CTDPA will slot in between the VCDPA and UCPA, taking effect on July 1, 2023, albeit without interpretive rulemaking or regulations. 

The CTDPA explicitly does not create a private right of action for statutory violations. The CT AG has “exclusive authority” to enforce the law. For the first 18 months (from July 1, 2023 to December 31, 2024), the CT AG must issue a notice of violation to the controller and provide an opportunity to cure the alleged violation within 60 days of receipt of the notice. Beginning January 1, 2025, the CT AG has discretion to grant such an opportunity to cure an alleged violation. Statutory violations of the CTDPA constitute an unfair trade practice under the Connecticut Unfair Trade Practices Act (“CUTPA”), which authorizes injunctive relief and civil penalties of up to $5,000 per violation for willful misconduct (i.e., the business knew or should have known the activities violated the law). Only the CT AG may bring suit under the CUTPA.
