A contextual deep linking server receives a request associated with a valid contextual deep link from a client device, the contextual deep link associated with link data indicating a particular configuration of an application. The server also receives, after determining that the client device has stored a previously generated fingerprint, stored contextual information for the client device identified by a locally stored fingerprint that matches the previously generated fingerprint. The server then generates, after determining that the client device does not have the previously generated fingerprint, a unique fingerprint of the client device based on a plurality of characteristics of the client device and determining contextual information of the request based on a characteristic of the client device. The server also transmits a response to the client device that is selected based on the contextual information of the client device such that the response is operable on the client device.
