What triggers it
The lint's definition. It stores or reads information on a user's browser or device beyond what delivering the service needs: analytics or advertising cookies, pixels, SDK identifiers, fingerprinting.
This covers a device-fingerprinting technique, an advertising identifier your app reads, and a tracking cookie set for a returning visitor.
What does not
A session token that only keeps a single visit logged in, and is discarded when the visit ends, does not count in the same way.
Often confused with Records text chat.

Counterparties that usually come with it
- an analytics provider
- an advertising network
- a crash-reporting service
A component that cannot run as documented without one of these names
it in its ACTIVITIES.md under talks_to, with
required: true. That party's jurisdiction then joins the
run of every product that uses the component, and the finding says
why it is there. A default the deployer can change is asked about,
never added. Talking to a party never makes a product that party.
In a declaration
A library or framework that makes this possible enables
it; an application whose shipped code does it performs it.
