Bowcast privacy policy
Effective July 5, 2026
Bowcast forecasts the chance of seeing a rainbow around you. It is built to know as little about you as possible.
Location
Bowcast uses your approximate location to compute rainbow chances for the area around you. Forecasts are computed on your device: your location is sent only to the weather data provider (Open-Meteo) as forecast coordinates, never with your name or any account identifier. If you deny location access, you can search for a place instead, and only that place's coordinates are used.
Rainbow alerts
If you turn on alerts, we store two things on our server: your device's push token and the coordinates you registered with, so we can send alerts for your area. Turning alerts off deletes the token from our server. We send alerts through Google Firebase Cloud Messaging and Apple Push Notification service, which process the delivery.
What we do not do
- No accounts, no names, no email addresses.
- No analytics or tracking SDKs.
- No sale or sharing of personal data with anyone.
Service providers
- Open-Meteo: weather forecast data (receives forecast coordinates).
- CARTO and OpenStreetMap: map imagery.
- Google Firebase / Apple APNs: push notification delivery (only if alerts are on).
Advertising
Bowcast currently shows no ads. If ads are added to a future version, this policy will be updated first and the app will ask for any consent the law requires.
Data deletion and contact
Turning off alerts removes your push registration. Everything else lives only on your device and is deleted when you remove the app. For any request or question, contact i@shamseddin.net.
