In some implementations, a method for managing data in a user device includes pushing first metadata for a first resource in a first perimeter to a service external to the first perimeter. The first perimeter is configured to prevent external resources from accessing resources in the first perimeter. Second metadata for a second resource in a second perimeter is pushed to the external service. The external service is external to the second perimeter, the second perimeter being configured to prevent external resources from accessing resources in the second perimeter. Information is presented to the user based on a combination of the first metadata and the second metadata.
