Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for distributing digital component while securing user data are described. In one aspect, a method includes receiving, by a multi-platform server and from a client device, a request for a digital component for presentation by the client device. The request for the digital component includes (i) request data that is opaque to the multi-platform server, and (ii) sensitive user data that is managed by the client device. In response to receiving the request for the digital component, the multi-platform server transmits, to a first content platform, a contextual request that includes the request data from the client device and that does not include the sensitive user data. After transmitting the contextual request, the multi-platform server receives, from the first content platform, a contextual response that includes a selection data unit for a first repository of digital components.
