A mobile device enabled tiered data exchange via a vehicle is disclosed. A mobile device can access profile information related to a tiered-data sharing profile. The tiered-data sharing profile can associate data with a sharing tier designating security, privacy, or authorization constraints on sharing the associated data. A sharing tier can further designate obfuscation of the data as a constraint on sharing the data. The mobile device can enable access to the data subject to the constraints of the tiered-data sharing profile. In an embodiment, tiered data can be shared from the mobile device to an external service device via vehicle device. In another embodiment, tiered data can be shared from the mobile device to a service device of the vehicle.
