Bellweathered
Privacy policy · effective October 16, 2026
Bellweathered plays the weather, the sun and the moon where you are. It has no accounts, ads, analytics or tracking, and it never sends anything to the developer.
Location
If you allow it, Bellweathered asks iOS for your approximate location (to about a kilometre) while the app is open. It uses it in three ways:
- Weather: your coordinates, rounded to two decimal places (roughly 1 km), are sent to Open-Meteo, a free weather service, to fetch the current conditions. No other information is attached. See Open-Meteo's terms for how they handle requests.
- Place name: iOS's built-in geocoding service (provided by Apple) turns your location into a town name to show on screen.
- Sun and moon: their positions are calculated on your iPhone.
Your location is kept in memory only and is not stored or shared beyond the above. If you don't allow location, Bellweathered uses a default place or a simulated sky.
Duo with Aether
When Duo is on (it is by default, for a few minutes after launch; you can turn it off in Settings › Duo), Bellweathered looks for the Aether app on a nearby iPhone using Apple's peer-to-peer connection (Bluetooth or direct Wi-Fi, no internet). When connected, the two exchange musical information directly with each other, encrypted: key, scale, tempo, chord changes, and a short summary of conditions (for Bellweathered: temperature, cloud, rain chance, wind, daylight and the place name it displays). Nothing is sent anywhere else. You can turn the search off at any time.
Stored on your device
Bellweathered remembers only your duo preferences and a random name for duo pairing. Deleting the app removes them.
Children
Bellweathered does not knowingly collect personal data from anyone, including children; the location use above is the only data that leaves the device, and only to fetch weather and a place name.
