- Right to Correct: You may request we correct the inaccurate personal information that we have about you.
If you are in Europe, in addition to the rights above, you may have the right to object to certain processing or request we restrict certain processing.
To exercise any of these rights, please use our Consumer Rights Request Portal. You may also make a request by calling us at 1-888-655-1873. When you make such a request, we will take steps to verify your identity, such as by asking you to confirm access to the email address associated with the request or asking you to confirm other information to help ensure we are interacting with the individual making the request. If we deny a request you make, you may have the right to appeal our decision by contacting us at privacy@viantinc.com. If you have concerns about our response to your appeal, you may have the right to contact you’re the attorney general in your state.

If you live in California, you may also permit an authorized agent to make a right to know, deletion, or correction request on your behalf, subject to appropriate verification of the agent’s authority to submit requests on your behalf. For example, we may ask authorized agents for proof of their authority to operate on your behalf, such as power of attorney, or we may ask you to provide confirmation that you gave the agent permission to make such a request. Please use our Consumer Rights Request Portal to make a request as an authorized agent.
