How we choose which country to show you

The menu shows your country’s section, if it has one. To know your country, we use your device’s time zone: it is read in your browser and never sent anywhere. If you prefer another country, pick it in the section’s country selector and this browser will remember it; the same selector lets you go back to using your location.
