The portal names nineteen states whose residents may have additional data-subject rights with it: California, Colorado, Connecticut, Delaware, Indiana, Iowa, Kentucky, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, Rhode Island, Tennessee, Texas, Utah, and Virginia. Those rights include the right to know whether your personal information is being processed and to request access to it, and the right to request correction. If a plain opt-out stalls, a rights request naming your state statute is a reasonable follow-up.
California residents have a further option. InfoPay, Inc. appears on the state's data-broker registry, so California residents can also make a deletion request through the state's DROP mechanism.
