Tearline provides open source intelligence to the public.
The National Geospatial-Intelligence Agency (NGA) is partnering with expert non-profit groups to grow public-facing, authoritative open source intelligence on various strategic, economic, and humanitarian intelligence topics that tend to be under-reported within in-depth or long-form formats.

The public functions that run without authentication (no username/password) collect basic Tearline app usage data such as course location and device ID. This basic information is used by web metrics software to note high-level trends like you would see from any basic website analytic platform. NGA neither collects nor acquires any user names, passwords or other login information or personal information from Apple or Google.
For authenticated users, Tearline is an intranet application for official US government business. Federal systems monitoring practices apply to government employees and guest authors within the authenticated service.
