Connecticut SB 4 surveillance pricing ban (2026)
Connecticut — SB 4 (Public Act 26-64): Ban on Retail and Delivery Surveillance Pricing Using Personal Data (Signed May 27, 2026)
Connecticut · Conn. Pub. Act 26-64, § 11 (Substitute S.B. 4, 2026) — approved May 27, 2026; effective October 1, 2026
- Status
- In effect
- Took effect
- October 1, 2026
- Applies to
- Retail sellers operating in Connecticut and third-party delivery services setting consumer prices.
- Enforced by
- Connecticut Office of the Attorney General; Department of Consumer Protection
Connecticut Governor Ned Lamont signed Senate Bill 4 on May 27, 2026 (Public Act 26-64), and its surveillance-pricing rules take effect October 1, 2026. The law bars retail sellers and third-party delivery services from 'surveillance pricing' — setting a customized price for a particular shopper based on personal data gathered through tracking technology such as cameras, sensors, biometric monitoring or device tracking. Ordinary discounts, loyalty programs, cost-based differences and supply-and-demand price changes are still allowed. Separately, any business that uses a 'price setting device' to raise online prices must tell shoppers: 'THIS PRICE WAS INCREASED BY A PRICE SETTING DEVICE USING YOUR PERSONAL DATA.' Only the Attorney General can enforce it, under the state's unfair trade practices law; shoppers cannot sue. The ban arrived as part of a broader overhaul of the state's privacy law rather than as a standalone measure. It is broader in reach than Maryland's Protection from Predatory Pricing Act signed weeks earlier: Maryland's applies to food retailers above 15,000 square feet and third-party delivery services, whereas Connecticut's covers retail sellers generally alongside delivery services.
Who is protected: Connecticut consumers purchasing from retail sellers and third-party delivery services, protected from being charged individually customized prices derived from their personal data.
Legal detail
Connecticut Public Act 26-64 (Substitute SB 4, 'An Act Concerning Consumer Privacy and Protection'), approved May 27, 2026; all sections effective October 1, 2026. Sec. 11 defines 'surveillance pricing' as establishing a customized price for a consumer good or service specific to a consumer based in whole or part on personal data collected through technology (biometric monitoring, cameras, device tracking, sensors) by the price-setter directly or via third-party data acquisition. Sec. 11(c): no RETAIL SELLER (a retailer under § 12-407 making retail sales of tangible personal property, including retail food establishments) or THIRD-PARTY DELIVERY SERVICE doing business in the state shall engage in surveillance pricing; carve-outs for retention discounts on services, justifiable cost or temporal (supply-and-demand) differences, and discounts under publicly posted uniform terms, broadly defined groups (veterans, seniors, students, etc.) or opt-in loyalty programs. Sec. 11(b): any person using a 'price setting device' for other than a discount in online transactions must disclose 'THIS PRICE WAS INCREASED BY A PRICE SETTING DEVICE USING YOUR PERSONAL DATA.' Sec. 11(d) exempts insurance licensees, GLBA financial institutions and CT-supervised banks. Sec. 11(e): violations are CUTPA unfair or deceptive trade practices enforced solely by the Attorney General; no private right of action. SCOPE COMPARISON: Maryland's Protection from Predatory Pricing Act (HB 895, signed 2026-04-28, indexed as Maryland Predatory Pricing Act (surveillance pricing)) reaches food retailers with at least 15,000 square feet plus third-party delivery services; Connecticut reaches retail sellers generally plus delivery services. The rest of PA 26-64 covers data-broker registration, a deletion mechanism and Connecticut Data Privacy Act amendments.
