Montana Privacy Disclosure

How SIE Data complies with the Montana Consumer Data Privacy Act (MCDPA), and how Montana residents can use their rights.

Last updated: May 1, 2026

MCDPA — effective October 1, 2024

Quick summary

The MCDPA gives Montana residents access, correction, deletion, portability, and opt-out rights.
Montana uses a lower 50,000 consumer threshold, so smaller controllers fall under the law.
Sensitive data, including data on known children, requires opt-in consent.
SIE responds to verified requests within forty-five days at no charge.

1. Overview of the law

The Montana Consumer Data Privacy Act took effect on October 1, 2024. It applies to businesses that process personal data of at least 50,000 Montana residents, or 25,000 residents when more than a quarter of revenue comes from selling personal data. The law is enforced by the Montana Attorney General. SIE meets the 50,000 resident threshold and applies the MCDPA in full.

2. Your rights

Right of access. Confirm processing and get a copy of your personal data.
Right to correct. Fix inaccurate personal data.
Right to delete. Have personal data we hold about you erased.
Right to portability. Receive your data in a usable format.
Right to opt out. Stop targeted advertising, sale of personal data, and certain profiling.
Right to appeal. Appeal a denial within forty-five days.

3. How SIE complies

Montana requires us to honor a Universal Opt-Out Mechanism by January 1, 2025. We honor the Global Privacy Control browser signal as a valid opt-out for targeted advertising and sale of personal data. We obtain opt-in consent before processing sensitive data, including data revealing race, religion, health, sexual orientation, citizenship, genetic or biometric data for identification, precise geolocation, and data of a known child.

4. Authorized agents

Montana allows authorized agents for opt-out requests. The agent should provide written authorization signed by you. We may verify the request with you directly before acting on it.

6. Effective date and scope

The MCDPA took effect on October 1, 2024. The 50,000 resident threshold is one of the lowest in the country, so most national data businesses are covered. The law covers Montana residents acting in a personal or household context.
