Montana Consumer Data Privacy Act — MCA Title 30, ch. 14, part 28
Montana's comprehensive consumer-privacy act, enacted by Ch. 681, L. 2023 and substantially amended by Ch. 567, L. 2025 (the enacting and amending chapters each section's History credit names). It carries the familiar controller/processor structure — consumer rights of access, correction, deletion and portability with opt-outs from sale, targeted advertising and profiling; controller duties of minimisation, security and transparency; mandatory processor contract terms; and data protection assessments — enforced by the Attorney General alone.
Biometric data is sensitive data when processed for the purpose of uniquely identifying an individual, and sensitive data may not be processed without consent. Montana's distinctive feature is that its three minors-facing sections — the duty of care owed to minors with its rebuttable presumption (30-14-2811), the responsibility-by-role and minors' processing rules (30-14-2818) and the data protection assessment for a heightened risk of harm to minors (30-14-2819) — are carved out of the volume thresholds by 30-14-2803(2) and bind any person who conducts business in Montana or targets commercial products or services at its residents, however few.

- (e) opt out of the processing of the consumer's personal data for the purposes of:
(2) A consumer may exercise rights under this section by a secure and reliable means established by the controller and described to the consumer in the controller's privacy notice.

- (a) A controller shall respond to the consumer without undue delay, but not later than 45 days after receipt of the request.

- (ii) opting the consumer out of the processing of the consumer's personal data for any purpose except for those exempted pursuant to the provisions of this part.

(8) Whenever a controller makes a material change to the controller's privacy notice or practices, the controller shall notify consumers affected by the material change with respect to any prospectively collected personal data and provide a reasonable opportunity for consumers to withdraw consent to any further materially different collection, processing, or transfer of previously collected personal data under the changed policy. The controller shall take all reasonable electronic measures to provide notification regarding material changes to affected consumers, taking into account available technology and the nature of the relationship.
(9) A controller is not required to provide a separate Montana-specific privacy notice or section of a privacy notice if the controller's general privacy notice contains all of the information required by this section.
(10) The privacy notice must be posted online through a conspicuous hyperlink using the word "privacy" on the controller's website homepage or on a mobile device's application store page or download page. A controller that maintains an application on a mobile device or other device shall also include a hyperlink to the privacy notice in the application's settings menu or in a similarly conspicuous and accessible location. A controller that does not operate a website shall make the privacy notice conspicuously available to consumers through a medium regularly used by the controller to interact with consumers, including but not limited to mail.
- (a) A controller shall establish and describe in a privacy notice one or more secure and reliable means for consumers to submit a request to exercise their consumer rights pursuant to this part considering the ways in which consumers normally interact with the controller, the need for secure and reliable communication of consumer requests, and the ability of the controller to verify the identity of the consumer making the request.
- (b) A controller may not require a consumer to create a new account to exercise consumer rights but may require a consumer to use an existing account.
MCA §30-14-2813. Data processor -- allowances -- limitations
(1) A processor shall adhere to the instructions of a controller and shall assist the controller in meeting the controller's obligations under this part to include:
- (a) considering the nature of processing and the information available to the processor by appropriate technical and organizational measures as much as reasonably practicable to fulfill the controller's obligation to respond to consumer rights requests;
- (b) considering the nature of processing and the information available to the processor by assisting the controller in meeting the controller's obligations in relation to the security of processing the personal data and in relation to the notification of a breach of security, as provided for in 30-14-1704, of the system of the processor to meet the controller's obligations; and
- (c) providing necessary information to enable the controller to conduct and document data protection assessments.
(2) A contract between a controller and a processor must govern the processor's data processing procedures with respect to processing performed on behalf of the controller. The contract must be binding and clearly set forth instructions for processing data, the nature and purpose of processing, the type of data subject to processing, the duration of processing, and the rights and obligations of both parties. The contract must also require that the processor:
- (a) ensure that each person processing personal data is subject to a duty of confidentiality with respect to the personal data;
- (b) at the controller's direction, delete or return all personal data to the controller as requested at the end of the provision of services, unless retention of the personal data is required by law;
- (c) on the reasonable request of the controller, make available to the controller all information in the processor's possession necessary to demonstrate the processor's compliance with the obligations in this part;
- (d) engage any subcontractor pursuant to a written contract that requires the subcontractor to meet the obligations of the processor with respect to the personal data; and
- (e) allow and cooperate with reasonable assessments by the controller or the controller's designated assessor, or the processor may arrange for a qualified and independent assessor to assess the processor's policies and technical and organizational measures in support of the obligations under this part using an appropriate and accepted control standard or framework and assessment procedure for the assessments. The processor shall provide a report of the assessment to the controller on request.
(3) Nothing in this section may be construed to relieve a controller or processor from the liabilities imposed on the controller or processor by virtue of the controller's or processor's role in the processing relationship, as described in this part.
(4) Determining whether a person is acting as a controller or processor with respect to a specific processing of data is a fact-based determination that depends on the following context in which personal data is to be processed:
- (a) A person who is not limited in the processing of personal data pursuant to a controller's instructions or who fails to adhere to a controller's instructions is a controller and not a processor with respect to a specific processing of data.
- (b) A processor that continues to adhere to a controller's instructions with respect to a specific processing of personal data remains a processor.
- (c) If a processor begins, alone or jointly with others, determining the purposes and means of the processing of personal data, the processor is a controller with respect to the processing and may be subject to an enforcement action under 30-14-2817.
MCA §30-14-2814. Data protection assessment
(1) A controller shall conduct and document a data protection assessment for each of the controller's processing activities that presents a heightened risk of harm to a consumer. For the purposes of this section, processing that presents a heightened risk of harm to a consumer includes:
- (a) the processing of personal data for the purposes of targeted advertising;
- (b) the sale of personal data;
- (c) the processing of personal data for the purposes of profiling in which the profiling presents a reasonably foreseeable risk of:
- (i) unfair or deceptive treatment of or unlawful disparate impact on consumers;
- (ii) financial, physical, or reputational injury to consumers;
- (iii) a physical or other form of intrusion on the solitude or seclusion or the private affairs or concerns of consumers in which the intrusion would be offensive to a reasonable person; or
- (iv) other substantial injury to consumers; and
- (d) the processing of sensitive data.
- (a) Data protection assessments conducted pursuant to subsection (1) must identify and weigh the benefits that may flow, directly and indirectly, from the processing to the controller, the consumer, other stakeholders, and the public against the potential risks to the rights of the consumer associated with the processing as mitigated by safeguards that may be employed by the controller to reduce these risks.
- (b) The controller shall factor into any data protection assessment the use of de-identified data and the reasonable expectations of consumers, as well as the context of the processing and the relationship between the controller and the consumer whose personal data will be processed.
- (a) The attorney general may require that a controller disclose any data protection assessment that is relevant to an investigation conducted by the attorney general, and the controller shall make the data protection assessment available to the attorney general.
- (b) The attorney general may evaluate the data protection assessment for compliance with the responsibilities set forth in this part.
- (c) Data protection assessments are confidential and are exempt from disclosure under the Freedom of Information Act, 5 U.S.C. 552.
- (d) To the extent any information contained in a data protection assessment disclosed to the attorney general includes information subject to attorney-client privilege or work product protection, the disclosure may not constitute a waiver of the privilege or protection.
(4) A single data protection assessment may address a comparable set of processing operations that include similar activities.
(5) If a controller conducts a data protection assessment for the purpose of complying with another applicable law or regulation, the data protection assessment must be considered to satisfy the requirements established in this section if the data protection assessment is reasonably similar in scope and effect to the data protection assessment that would otherwise be conducted pursuant to this section.
(6) Data protection assessment requirements must apply to processing activities created or generated after January 1, 2025, and are not retroactive.
MCA §30-14-2815. De-identified data
- (a) take reasonable measures to ensure that the de-identified data cannot be associated with an individual;
- (b) publicly commit to maintaining and using de-identified data without attempting to re-identify the de-identified data; and
- (c) contractually obligate any recipients of the de-identified data to comply with all provisions of this part.
- (a) require a controller or processor to re-identify de-identified data or pseudonymous data; or
- (b) maintain data in identifiable form or collect, obtain, retain, or access any data or technology to be capable of associating an authenticated consumer request with personal data.
(3) Nothing in this part may be construed to require a controller or processor to comply with an authenticated consumer rights request if the controller:
- (a) is not reasonably capable of associating the request with the personal data or it would be unreasonably burdensome for the controller to associate the request with the personal data;
- (b) does not use the personal data to recognize or respond to the specific consumer who is the subject of the personal data or associate the personal data with other personal data about the same specific consumer; and
- (c) does not sell the personal data to any third party or otherwise voluntarily disclose the personal data to any third party other than a processor, except as otherwise permitted in this section.
(4) The rights afforded under 30-14-2808(1)(a) through (1)(d) may not apply to pseudonymous data in cases in which the controller is able to demonstrate that any information necessary to identify the consumer is kept separately and is subject to effective technical and organizational controls that prevent the controller from accessing the information.
(5) A controller that discloses pseudonymous data or de-identified data shall exercise reasonable oversight to monitor compliance with any contractual commitments to which the pseudonymous data or de-identified data is subject and shall take appropriate steps to address any breaches of those contractual commitments.
MCA §30-14-2816. Compliance by controller or processor
- (a) comply with federal, state, or municipal ordinances or regulations;
- (b) comply with a civil, criminal, or regulatory inquiry, investigation, subpoena, or summons by federal, state, municipal, or other government authorities;
- (c) cooperate with law enforcement agencies concerning conduct or activity that the controller or processor reasonably and in good faith believes may violate federal, state, or municipal ordinances or regulations;

- (i) prevent, detect, protect against, or respond to security incidents, identity theft, fraud, harassment, malicious or deceptive activities, or any illegal activity, preserve the integrity or security of systems, or investigate, report, or prosecute those responsible for any of these actions;
- (j) engage in public or peer-reviewed scientific or statistical research in the public interest that adheres to all other applicable ethics and privacy laws and is approved, monitored, and governed by an institutional review board that determines or similar independent oversight entities that determine:
- (i) whether the deletion of the information is likely to provide substantial benefits that do not exclusively accrue to the controller;
- (ii) the expected benefits of the research outweigh the privacy risks; and
- (iii) whether the controller has implemented reasonable safeguards to mitigate privacy risks associated with research, including any risks associated with re-identification;
- (k) assist another controller, processor, or third party with any of the obligations under this part; or
- (l) process personal data for reasons of public interest in public health, community health, or population health, but solely to the extent that the processing is:
(2) The obligations imposed on controllers or processors under this part may not restrict a controller's or processor's ability to collect, use, or retain personal data for internal use to:
- (a) conduct internal research to develop, improve, or repair products, services, or technology;
- (b) effectuate a product recall;
- (c) identify and repair technical errors that impair existing or intended functionality; or
- (d) perform internal operations that are reasonably aligned with the expectations of the consumer or reasonably anticipated based on the consumer's existing relationship with the controller or are otherwise compatible with processing data in furtherance of the provision of a product or service specifically requested by a consumer or the performance of a contract to which the consumer is a party.
(3) The obligations imposed on controllers or processors under this part may not apply when compliance by the controller or processor with this part would violate an evidentiary privilege under the laws of this state. Nothing in this part may be construed to prevent a controller or processor from providing personal data concerning a consumer to a person covered by an evidentiary privilege under the laws of this state as part of a privileged communication.
(4) A controller or processor that discloses personal data to a processor or third-party controller in accordance with this part may not be considered to have violated this part if the processor or third-party controller that receives and processes the personal data violates this part provided, at the time the disclosing controller or processor disclosed the personal data, the disclosing controller or processor did not have actual knowledge that the receiving processor or third-party controller would violate this part. A receiving processor or third-party controller receiving personal data from a disclosing controller or processor in compliance with this part is likewise not in violation of this part for the transgressions of the disclosing controller or processor from which the receiving processor or third-party controller receives the personal data.
- (a) impose any obligation on a controller or processor that adversely affects the rights or freedoms of any person, including but not limited to the rights of any person:
- (b) apply to a person's processing of personal data during the person's personal or household activities; or
- (c) require a controller or processor to implement an age verification or age-gating system or otherwise affirmatively collect the age of consumers, but a controller that chooses to conduct commercially reasonable age estimation to determine which consumers are minors is not liable for an erroneous age estimation.
(6) Personal data processed by a controller pursuant to this section may be processed to the extent that the processing is:
- (a) reasonably necessary and proportionate to the purposes listed in this section; and
- (b) adequate, relevant, and limited to what is necessary in relation to the specific purposes listed in this section. The controller or processor must, when applicable, consider the nature and purpose of the collection, use, or retention of the personal data collected, used, or retained pursuant to subsection (2). The personal data must be subject to reasonable administrative, technical, and physical measures to protect the confidentiality, integrity, and accessibility of the personal data and to reduce reasonably foreseeable risks of harm to consumers relating to the collection, use, or retention of personal data.
(7) If a controller processes personal data pursuant to an exemption in this section, the controller bears the burden of demonstrating that the processing qualifies for the exemption and complies with the requirements in subsection (6).
(8) Processing personal data for the purposes expressly identified in this section may not solely make a legal entity a controller with respect to the processing.
MCA §30-14-2817. Enforcement
(1) The attorney general has exclusive authority and may use the duties and powers provided by Title 30, chapter 14, parts 1 and 2, to enforce violations pursuant to this part.

The attorney general may evaluate the data protection assessment for compliance with the requirements pursuant to this part.
(4) Actions brought by the department to enforce this part are subject to the statute of limitations pursuant to 27-2-231.
(5) Nothing in this part may be construed as providing the basis for or be subject to a private right of action for violations of this part or any other law.
MCA §30-14-2818. Responsibility according to role -- processing data of minors
(1) A processor shall adhere to the instructions of a controller and shall assist the controller to meet the controller's obligations under 30-14-2811 and 30-14-2819, taking into account the nature of the processing and the information available to the processor. The processor shall assist the controller by:
- (a) taking appropriate technical and organizational measures, insofar as this is possible, for the fulfillment of the controller's obligations under 30-14-2811; and
- (b) providing information to enable the controller to conduct and document data protection assessments pursuant to 30-14-2819.
(3) Nothing in this section may be construed to relieve a controller or processor from the liabilities imposed on the controller or processor by virtue of the controller's or processor's role in the processing relationship as described in 30-14-2811 and 30-14-2819.
(4) Determining whether a person is acting as a controller or processor with respect to a specific processing of personal data is a fact-based determination that depends on the context in which personal data is to be processed. A person that is not limited in the person's processing of personal data pursuant to a controller's instructions or that fails to adhere to the instructions is a controller and not a processor with respect to a specific processing of personal data. A processor that continues to adhere to a controller's instructions with respect to a specific processing of personal data remains a processor. If a processor begins, alone or jointly with others, determining the purposes and means of the processing of personal data, the processor is a controller with respect to the processing and may be subject to an enforcement action under 30-14-2817.
MCA §30-14-2819. Data protection assessments for heightened risk of harm to minors
(1) A controller that, on or after October 1, 2025, offers an online service, product, or feature to a consumer whom the controller actually knows or willfully disregards is a minor shall conduct a data protection assessment for the online service, product, or feature if there is a heightened risk of harm to minors.

- (b) to address:
- (i) the purpose of the online service, product, or feature;
- (ii) the categories of a minor's personal data that the online service, product, or feature processes;
- (iii) the purposes for which the controller processes a minor's personal data with respect to the online service, product, or feature; and
- (iv) a heightened risk of harm to minors that is a reasonably foreseeable result of offering the online service, product, or feature to minors.
- (a) review the data protection assessment as necessary to account for a material change to the processing operations of the online service, product, or feature that is the subject of the data protection assessment; and
- (b) maintain documentation concerning the data protection assessment for the longer of:
(3) A single data protection assessment may address a comparable set of processing operations that include similar activities.

(5) If a controller conducts a data protection assessment pursuant to subsection (1) or a data protection assessment review pursuant to subsection (2)(a) and determines that the online service, product, or feature that is the subject of the assessment poses a heightened risk of harm to minors, the controller shall establish and implement a plan to mitigate or eliminate the heightened risk.
- (a) A data protection assessment conducted pursuant to this section:
