Palantir may not be printing this on t-shirts, but they aren't that secretive about what they do.
Let's say you're an FBI agent with a warrant that allows you to spy on Joe Schmo, and any of his foreign contacts (not named individually). And maybe you're doing this because of ties to drug smuggling, so you're allowed to ignore the fourth amendment when dealing with some particular data source, but other sources are only allowed within the scope of the warrant.
Palantir (or at least one of their products) allows querying across those data sources within the bounds of the warrant. So rather than the good old days when "secure in their persons and papers" meant that you could actually keep your data private, with Palantir, the government has moved the position that until a human sees it, it doesn't count.
