Abstract: In some implementations, a computing system can be configured to perform personalized content item selection in a privacy preserving manner. In some implementations, user privacy can be protected by performing the personalized selection of content items on the user's device. For example, the computing system can include a client device configured to select content items from a collection of candidate content items received from a server device based on a user profile generated and stored on the client device. In some implementations, user privacy can be protected when performing the personalized selection of content items by sending an anonymous, or approximate, user profile (e.g., class profile) to the server device. For example, the computing system can include a server device configured to select content items from a collection of content items based on a class profile representing a group of similar user profiles received from the client device.
