WeatherDuo is a weather app. We built it to collect as little as possible.

What we collect

Location. If you allow it, WeatherDuo uses your device's location to show the weather where you are. The coordinates of your location, and of any cities you add, are sent to our weather data providers only to retrieve forecasts.

That is the only data that leaves your device.

What we don't do

• No accounts. We don't ask for your name, email or any other personal details.
• No advertising and no tracking. We don't share data with advertisers or data brokers.
• No analytics. We don't record how you use the app.

Weather data providers

• Apple WeatherKit provides our weather data. See Apple's privacy policy at apple.com/privacy.
• OpenWeatherMap provides backup weather data when WeatherKit is unavailable. See openweathermap.org/privacy-policy.
• Apple MapKit is used when you search for a city.

These providers receive coordinates or search text only, never your identity.

Data stored on your device

Your saved cities, your preferred temperature unit and recent forecasts are stored on your device so the app and its widgets load quickly. Deleting the app removes them.

Children

WeatherDuo is suitable for all ages and does not knowingly collect personal information from children.

Changes

If this policy changes, we'll update the date above.
