Privacy
Location Data
CastWindow may request access to your device location if you choose to use location-based features. We use your location to show nearby tides, weather, marine conditions, and map context.
We do not sell your location data. We do not use your location for advertising. We do not track your location in the background.
If location access is denied or unavailable, CastWindow uses a default fallback location (Dunedin / Honeymoon Island, Florida).
Location may be sent to CastWindow server routes only as needed to return nearby conditions. We avoid storing exact location and round coordinates to reduce precision before they are used.
- Data used: Approximate, rounded location — only when you grant permission.
- Purpose: Tides, weather, marine conditions, and map context.
- Sharing: Not sold, not shared for advertising, not used for tracking.
- Retention: Not stored beyond what is needed to serve the request — location is processed ephemerally.
- Your control: Permission is optional and can be denied or revoked anytime in your browser or device settings.
Product usage analytics
CastWindow collects limited, privacy-safe product usage analytics to understand which tools and map layers are used and whether environmental data loads reliably. Standard page-view analytics use Vercel Analytics. CastWindow also stores anonymous aggregate usage counters (totals only — not individual action logs).
We do not collect user or session identifiers, coordinates, map location, saved-location names, search text, notes, or device fingerprints for this analytics. We do not store a history of what any person did. Analytics failures never change tides, weather, map, or fishing tools.
Map & Chart Data
CastWindow map layers — bathymetry, shoreline imagery, and NOAA chart overlays — are for fishing context only. They are not intended for navigation, piloting, or safety-critical decisions.
Bathymetry and shoreline data come from surveys and imagery that may be months or years old. Shorelines, surf-zone sandbars, and troughs can shift after storms and may not match conditions on the water today.
CastWindow is a fishing intelligence tool. Habitat, reef, ENC-derived structure, bathymetry, and discovered-spot layers are not a substitute for official navigation charts, not a navigation safety system, and not a guarantee of depth, access, or hazard clearance.
