In short
The developer of Wetterzeit does not collect, store or transmit any personal data. There is no account, no advertising, no analytics or tracking, and no developer servers.
To show you the weather, the app requests weather data directly from Open-Meteo and the German Weather Service (Deutscher Wetterdienst). The selected location is sent, rounded to about one kilometre. Details below.

Processing on your device
The following is stored only on your iPhone and never sent to the developer:
- recently viewed places
- your date and place of birth, if you use the birthday weather
- destination and travel dates, if you use the holiday check
- your settings, for example which notifications you want
- cached weather data so the app starts faster
- the data for the Home Screen and Lock Screen widget
Deleting the app removes all of this data from your device.
Location
If you allow it, Wetterzeit uses your current location to show the weather where you are. The app only requests your location while you are using it. You can change this at any time in the iPhone Settings under Privacy & Security › Location Services › Wetterzeit. Without location access, you can pick any place using the search.
To show the name of your place, the app uses Apple's location service. Apple's privacy policy applies: apple.com/legal/privacy.
Weather data requests
The app requests weather data directly from the services below. It sends the coordinates of the selected place, rounded to two decimal places (about 1 km), and, for technical reasons, your device's IP address. No name, device identifier or other information about you is sent.
Open-Meteo
Current weather, forecast, rain in the next two hours, weather history since 1940, air quality, UV index, pollen and place search. When you search for a place, the search term is sent. More information: open-meteo.com/en/terms.
Deutscher Wetterdienst
Rain radar and official severe weather warnings for places in Germany. More information: dwd.de › Data protection.
The legal basis is Art. 6(1)(b) GDPR, as the transfer is needed to show you the weather data you requested. Without an internet connection the app cannot show current data.
Notifications and background refresh
Notifications about severe weather, rain and records are off by default. If you turn them on, the app creates them itself on your iPhone. There is no developer notification server. To keep notifications and the widget up to date, the app occasionally requests weather data for your most recently viewed place in the background, as described above. iOS decides when this happens.
Sharing
Images such as the climate stripes or the year in review are only shared when you start this yourself from the share menu. You decide where they go.
Your rights
As the developer does not collect personal data, no data about you is held by the developer. For data processed by Open-Meteo or the Deutscher Wetterdienst, you can also contact these services directly. For privacy questions, please contact me at the email address above. You also have the right to lodge a complaint with a data protection supervisory authority.
