Field notes

The page says users type in a town rather than grant location access, and that settings stay on the phone with no accounts, advertising, analytics, or data sales. Its described freeze checklist covers pipes, outdoor taps, pets, and a warning about heating a home with anything that burns; the page also cautions that reminders may not arrive and should not be treated as an emergency warning.
