FullContact Inc. is a privately held technology company that provides a suite of cloud-based software products for businesses, developers, and brands. FullContact (owned by Ziff Davis) builds an identity graph on people who are not its customers, and directs all access, deletion, correction and sale/targeted-advertising opt-out requests to its "Privacy Portal" interactive webform, or alternatively to privacy@fullcontact.com. The policy text links the Privacy Portal by name without printing a URL, so you may need to find it from the FullContact site footer ("Your Privacy Choices"). Notably, a request to limit use of sensitive data is treated as a deletion and removes your profile from the identity graph; no response timeline is stated, and they may ask for information to verify your identity.
