At InMarket, being best-in-class means providing our customers with access to the most accurate and precise, permission-based, SDK-derived location data available today. It also means creating breakthrough experiences via hyper-relevant, timely message... InMarket (a location/ad-targeting data company behind apps like CheckPoints, Key Ring and Out of Milk) links several dedicated request forms from its privacy policy page: 'Do Not Sell or Share My Personal Information (Opt-Out)', 'Delete My Personal Information', 'Access my Information', 'Limit the Use of My Sensitive Personal Information' and 'Update Inaccuracies'. You can also call toll-free 1 (877) 782-0530 or email privacy@inmarket.com. Because much of its data is tied to device advertising IDs, also turn off ad tracking/Location Services on your phone and enable Global Privacy Control in your browser, since a form opt-out applies only to the browser or device used.
