Local Deviations - US
Additional Information for Individuals Residing in the United States

Date last revised: November 1, 2026

These Local Deviations apply, together with the “TIER IV Privacy Policy” (the “Policy”), to the processing of personal information relating to residents of the United States. In the event of any inconsistency or conflict between these Local Deviations and the Policy, these Local Deviations prevail to the extent required by applicable law. California residents should also refer to the separately published “California Privacy Notice”, depending on their relationship with the Covered Companies.

Applicable TIER IV Group Companies

The companies covered by these Local Deviations are TIER IV, Inc. and Tier IV North America Inc. (collectively, the “Covered Companies”). In these Local Deviations, “we”, “us” and “our” refer to the Covered Company or Companies subject to the obligations under applicable US state law with respect to a particular processing of personal information. The company subject to those obligations with respect to a particular processing is determined by reference to the company conducting the processing, its relationship with you, the purposes and essential means of the processing, the requirements under applicable state law and other circumstances.

Roles of the Covered Companies

Where Tier IV North America Inc. provides business contact information obtained from partners or prospective customers to TIER IV, Inc. and TIER IV, Inc. uses that information for customer acquisition, communications and similar purposes, the role of each company is likewise determined by reference to which entity substantively determines the purposes and essential means, the discretion over the collection and use of the information, instruction relationships and other actual circumstances of the processing, and applicable law.

Privacy Rights of Residents of Certain US States

Under applicable state law, residents of certain US states may have, in addition to the rights described in “Your Rights and How to Exercise Them” in the Policy, the right to opt out of the sale of personal information or personal data, of processing for the purposes of targeted advertising, and of profiling in furtherance of decisions that produce legal or similarly significant effects concerning them; the right to consent, or withdraw consent, to the processing of sensitive data; the right to appeal our response to a rights request; and other rights. Whether these rights are available, and their content, conditions of exercise and limitations, are governed by the applicable law of the state in which you reside. We do not sell personal information, process personal information for the purposes of targeted advertising, or engage in the profiling described above.

How to Exercise Your Rights

If you wish to exercise your rights, please contact us using the contact details set out in “Contact Us” below. In your request, please include your name, contact details, state of residence, the right you wish to exercise, the relevant product or service or your relationship with us, and any other information reasonably necessary for us to identify and respond to your request. California residents exercising their rights under the CCPA should follow the methods described in the “California Privacy Notice”, depending on their relationship with us.

Identity Verification and Requests through Agents

In accordance with applicable law, we verify your identity or the authority of your agent to the extent necessary to respond to your request. To verify your identity, we may use reasonable methods appropriate to the nature of the request and of the personal information, such as matching against information we hold or confirmation through your registered email address. If we are unable to verify your identity, we may be unable to respond to all or part of your request, in accordance with applicable law.
Where you submit a request through an agent as permitted by applicable law, we may require the agent to provide documentation showing that you have authorized the agent, or require you to verify your identity or confirm that you have authorized the agent.

Responses and Appeals

We respond to rights requests within the period prescribed by applicable state law. Where reasonably necessary, we may extend the response period to the extent permitted by applicable law and will notify you of the extension and the reasons for it. If we decline all or part of your request, we will notify you of the reasons and of the available means of appeal, in accordance with applicable law.
Where applicable state law grants you a right to appeal, please contact us using the contact details set out in “Contact Us” below, stating that you are submitting an appeal, including information that identifies your original request and stating the reasons for your appeal. We will review your appeal within the period prescribed by applicable law and notify you of the outcome.
