Yes, ad blockers are legal in Colorado, but their use is constrained by consumer protection and anti-deception laws. The Colorado Consumer Protection Act (CCPA) prohibits deceptive practices, including misleading users about data collection or ad blocking functionality. Courts have not yet ruled on ad blockers specifically, but existing precedents suggest compliance hinges on transparency. The Colorado Attorney General’s Office (AGO) has not issued formal guidance, though its 2026 enforcement priorities may address digital privacy tools.
Key Regulations for Ad Blockers in Colorado
- Consumer Protection Act (CCPA): Prohibits deceptive acts, such as ad blockers that falsely claim to protect privacy while surreptitiously collecting user data. Violations may trigger civil penalties under §6-1-706.
- Unfair Trade Practices: Ad blockers that interfere with contractual agreements between users and websites (e.g., bypassing paywalls) could violate §6-1-105 if deemed unfair or unconscionable.
- Data Privacy Laws: Under the Colorado Privacy Act (CPA), ad blockers must disclose data processing activities to avoid enforcement by the AGO, which has authority to investigate non-compliance starting July 2026.
Ad blockers operate in a legal gray area where their permissibility depends on compliance with existing statutes. Websites in Colorado may enforce anti-ad-blocking measures via terms of service, but these cannot override consumer protection statutes. The AGO’s upcoming 2026 rulemaking on digital privacy tools may further clarify obligations. Businesses and users should monitor updates from the AGO’s newly formed Digital Privacy Unit.
