GPS accuracy depends on several factors: signal strength, terrain (buildings, trees), and your device's antenna. We recommend enabling "High Accuracy" mode in location settings. In tunnels or underwater, GPS is unavailable, so we switch to accelerometer-based wave detection.
How do I cancel my subscription?+
To cancel Premium, go to Settings → Subscription → Manage Subscription → Cancel Renewal. Apple and Google will refund your prorated amount if you cancel within the first week. You'll lose access to premium features immediately, but your data is preserved.
How do I export my session data?+
Go to Profile → Settings → Data & Privacy → Export Data. You'll receive a ZIP file containing all your sessions in JSON format. This is GDPR-compliant and can be imported into other apps.
Why does the forecast sometimes differ from actual conditions?+
Our forecasts come from Open-Meteo and NOAA, which have 1-3 hour resolution. Local bathymetry (underwater topology), reefs, and wind shadows can significantly affect actual wave conditions. Forecasts are most accurate 24-48 hours out.
Is my data private and encrypted?+
Yes. Session data is stored locally on your device. When synced to cloud, it's encrypted in transit (HTTPS) and at rest (AES-256) on Firebase. See our Privacy Policy for full details.
