Privacy Policy

This Privacy Policy explains how SailWindow handles information.

Last updated: April 14, 2026

Overview

SailWindow is an iPhone marine forecast app. The app is designed to fetch marine weather data directly from public NOAA, National Weather Service, and National Data Buoy Center services. SailWindow does not operate a separate backend service.

Information You Enter

You may save sailing locations in the app. Saved locations can include names, latitude, longitude, NOAA zone metadata, and related forecast metadata. This information is stored locally on your device so the app can refresh forecasts for your saved spots.

Location Data

SailWindow uses the locations you enter or save to request weather forecasts, marine alerts, text forecasts, buoy observations, and radar map tiles from public weather services. The app does not collect precise device location in the background and does not sell location data.

Weather Data Requests

When SailWindow refreshes weather data or displays radar, your selected coordinates, NOAA zone identifiers, map tile coordinates, or map viewport may be included in requests to public NOAA, NWS, NDBC, RainViewer, OpenStreetMap, and related map library CDN endpoints. Those external services may receive standard technical information associated with web requests, such as IP address, request time, and user agent.

Notifications

If you enable notification rules, SailWindow evaluates those rules locally on your device against refreshed forecast and alert data. The app does not use a production push notification backend for these rules.

Analytics and Tracking

SailWindow does not include third-party advertising SDKs, does not track you across apps or websites, and does not sell personal information.

Data Sharing

SailWindow does not share your saved app data with the developer through a backend service. Weather requests are made directly to public weather data providers as needed to provide forecasts, alerts, and observations.

Data Storage and Deletion

Saved locations, cached forecasts, cached alerts, cached observations, and notification rules are stored locally on your device. You can remove saved locations in the app. You can also delete the app from your device to remove its local app data.

Children's Privacy

SailWindow is not directed to children and does not knowingly collect personal information from children.

Changes

This Privacy Policy may be updated as SailWindow changes. The updated date at the top of this page will reflect the latest version.
