Learn about tracking

When you read a story or check the rain, the app can record that action and send it to a server. These pages explain how that works.

1. How tracking works: from a tap to an event and an upload.
2. How identifiers connect activity: how a random code can link activity from one person or installation.
3. Location and useful service traffic: which data a weather or navigation app may still need to share.
4. Consent, advertisements and tracking: why these are separate controls.

Then pick a service you have seen named, or find your app. The glossary explains unfamiliar terms.
