Plumicast is a weather app that turns the forecast into quick outfit guidance. We've designed it to need as little of your data as possible, and to keep what it does need on your device.
If you grant location permission, Plumicast reads your current coordinates so it can request the forecast for where you are. The coordinates are sent to the weather provider (see below) solely to return a forecast for that point, and are not stored on any Plumicast server. You can use Plumicast without sharing your location by searching for a city instead; in that case no coordinates leave your device for that lookup.
On iOS, the home-screen and lock-screen widget refreshes in the background so your outfit for the day is ready when you glance at your phone. Background refresh uses the same weather lookup path as the app itself.
The cities you save, the mode you pick (Daily, Work, Workout), your activity setting, sensitivity, and any items you dismiss are stored locally on your device using the operating system's standard storage. They are not uploaded to us. Uninstalling Plumicast removes this data.
Plumicast Pro is purchased through the Apple App Store. Apple handles the payment and sends Plumicast a receipt so the app can confirm your entitlement. We never see your payment details, Apple ID, or billing address. Your Pro status is cached locally on your device so the app knows you've unlocked it.
On iOS, Plumicast uses Apple WeatherKit as its weather source. The app sends a latitude/longitude (or a searched city name) and receives a forecast in return. Use of this provider is governed by Apple's own terms:
Plumicast is rated 4+ and is suitable for all ages. It does not knowingly collect personal information from anyone, children included.
If we add features that change how data is handled, we'll update this page and bump the "last updated" date. Material changes will also be called out in the app changelog.
