Repackaging media content data with anonymous identifiers

Systems, methods, and computer-readable storage media for maintaining user anonymity in content statistics. A system can first receive a media content request from a client device. The media content request can include a user account identifier and a content identifier. The content identifier can be different and separate from the user account identifier and a device identifier associated with the client device, and the content identifier can identify content presented at the client device. Next, the system can store the user account identifier and the content identifier in separate locations without attributing the content identifier to the user account identifier. In response to the media content request, the system can transmit a media content item to the client device based on the user account identifier. The system can also report the content presented at the client device with the content identifier and without the user account identifier.
