Terms of Service

Effective 13 September 2026

The short, honest version of the deal between you and Sea Window.

The agreement

By using Sea Window you agree to these terms. Sea Window is operated by Lonka Pardhu, an independent developer. You can reach us at support@seawindow.app.

Subscription and billing

Sea Window is a paid app: a subscription that starts with a free trial. Billing is handled by your app store, the Apple App Store or Google Play, through your store account. The price and renewal date are always shown before you pay. You can cancel any time in your store's subscription settings; cancel at least 24 hours before the trial ends and you will not be charged. Refunds are handled by Apple or Google under their standard policies, described in our refund policy.

Weather and map data

Sea Window brings together forecasts from the ECMWF, ICON and GFS models, tide predictions from NOAA CO-OPS and a global tide model, and maps from Mapbox with NOAA nautical charts, OpenSeaMap seamarks and GEBCO depth contours. Forecasts update as each model runs, and the app shows when its data was last refreshed.

Liability

To the maximum extent permitted by law, Lonka Pardhu is not liable for indirect, incidental or consequential loss arising from your use of Sea Window. Nothing in these terms limits liability that cannot lawfully be limited.

Your account and content

Sea Window needs an account. Sign in with Apple, Google or email; the routes, trips and settings you save are stored with your account so they follow you between devices. You can delete your account from the Account tab at any time, which permanently removes that data.

Fair use

Please use the app as intended: do not scrape our weather endpoints, resell the data, or attempt to break or overload the service.

Changes

We may update these terms as the app evolves. If a change matters, we will flag it in the app; continuing to use Sea Window after that means you accept the updated terms.

App Store terms

If you got Sea Window from the Apple App Store, these additional terms apply, and Apple requires us to state them.
