The National Security Agency (NSA) commonly records Internet metadata for the whole planet for up to a year in its MARINA database, where it is used for pattern-of-life analysis. U.S. persons are not exempt because metadata are not considered data under US law (section 702 of the FISA Amendments Act).[68] Its equivalent for phone records is MAINWAY.[69] The NSA records SMS and similar text messages worldwide through DISHFIRE.[70]
