Our data-driven marketing tools help you understand who your best customers are and the best ways — what, when and how — to reach and motivate them. Allant is a registered California data broker. You can submit a deletion or do-not-sell/share request through its "Privacy Request Portal" (linked from the privacy policy), or by emailing privacy@allantgroup.com or calling (800) 367-7311. Deletion and specific-information requests require uploading a government-issued ID (and a selfie for specific-information requests), which can also be mailed to their Downers Grove, IL address. Allant says it will tell you within 10 days if it cannot fulfill your request; since it continually re-acquires data from third-party sources, it is worth re-checking periodically.
