Iowa SSB 3085 regulates the collection, retention, sale, and protection of biometric data by private (nongovernmental) entities. Private entities must develop a publicly available written retention policy, provide written notice and purpose disclosure before collecting biometric identifiers, and destroy biometric data no later than three years after the subject's last interaction or upon fulfillment of the collection purpose. The bill prohibits selling, leasing, trading, or otherwise profiting from biometric data and requires industry-standard security protections. Enforcement is exclusively through the Department of Inspections, Appeals, and Licensing (DIAL), which may seek injunctive relief and impose escalating civil penalties ($1,000/$5,000/$10,000). The bill exempts employers using employee biometric data solely within the scope of employment and government contractors acting in their governmental capacity, and it expressly does not create a private right of action.
