Abstract: Techniques are described for providing a promotional content server system for conditionally displaying promotional content to qualified users of client devices. In certain situations, advertising providers are enabled to remotely create and configure promotional offers via interactions with the promotional content server system. Information related to each offer is encoded as a promotional package and stored on client mobile devices of users, including in some situations to protect the stored packages to prevent unauthorized access to the offer or its associated terms and rewards. A client-side software module on a user's mobile device determines whether the user qualifies to receive the offer for a package based at least in part on private information stored on the client device, without making such information externally available. If the user is qualified, the client-side module displays an indication of the offer to the user on the mobile device.
