SurfSignal (“the App”) is provided by Sebastiaan Dalmeijer (“I”, “me”, “my”). This privacy policy explains how I handle information when you use the App.
Information I Collect
- App settings and alerts: The spots and wind/tide conditions you set in the App.
- Device identifiers: A Firebase Cloud Messaging token and install ID to send notifications and keep your alerts in sync across device and cloud.
- Forecast data: Weather and tide data fetched from third-party APIs (e.g., Stormglass, Mapbox).
No account, name, email, or payment details are collected.
How I Use Information
- To check weather and tide forecasts against your alert settings.
- To send a single daily push notification when your conditions are met.
- To keep your alerts backed up in the cloud, ensuring an alert can be evaluated at the selected daily notification time.
Data Storage
Your alerts and settings are stored locally on your device. A mirrored copy is stored securely in Firebase Cloud Firestore. I do not share, sell, or use your data for any other purpose.
Push Notifications
If enabled, the App may send you one push notification per day when your alert conditions are met. You can disable notifications in your device settings.
Offline Use
The App is designed to function even without internet. Data will sync automatically when connectivity is restored.
Children’s Privacy
The App is not directed to children under 13.
Changes
I may update this privacy policy from time to time. Changes will be posted on this page.
