Systems and methods are described for performing bulk transmissions of information (e.g., emergency information, etc.) while preserving user privacy. An example mobile device described herein includes an information aggregation module configured to compile first information associated with the device, the first information including location-related information, an encryption module communicatively coupled to the information aggregation module and configured to encrypt the first information using at least one session key, and a transmitter communicatively coupled to the encryption module and configured to transmit encrypted first information to at least one receiver prior to a triggering event and to transmit the at least one session key to the at least one receiver after the triggering event.
