Advertising experts helping businesses of all kinds! Warning: the text supplied for "JDM List Services" is actually Google's own Privacy Policy, so it contains no opt-out process for JDM List Services itself. The only mechanisms described are Google's self-service account tools (My Activity, My Ad Center, Delete your information) plus a generic "contact Google" link for U.S. state privacy-law requests; using those tools requires being signed in to a Google Account, and no response deadline is stated. To opt out of JDM List Services you will need to find that company's actual privacy contact.
