What it does
Comprehensive privacy law with access, correction, deletion, portability and opt-out rights. PA 25-113 (effective July 1, 2026) sharply lowered applicability thresholds, broadened sensitive data, added profiling impact assessments, and requires disclosure of whether personal data is used to train large language models. PA 26-64 (effective Oct 1, 2026) bans the sale of precise geolocation data and creates a data broker registry (registration required from Jan 1, 2027) and a state deletion mechanism brokers must honor from Oct 1, 2028.

Before July 1, 2026: 100,000+ consumers, or 25,000+ consumers and more than 25% of gross revenue from selling personal data.
- Penalties

Research notes
PA 25-113 is an omnibus act (also covers broadband, gaming, social media). Opt-out preference signal date (Jan 1, 2025) and CUTPA $5,000 willful-violation penalty are from the original act/CUTPA and not re-verified line by line. The DCP must establish the deletion mechanism by July 1, 2028. Consumer health data and minors' provisions added by PA 23-56 (2023) are folded into this record.
