License & attribution.

Plain-English summary

WAVOA the app is ours — code, brand, meteogram visualisations, sport-aware globe styling, color thresholds, recommendation logic. The forecast model data, map tiles, satellite imagery, and the open-source libraries that make the whole thing run all have their own licenses. They're all listed below in the order you'd encounter them, with attribution where required and a link to the upstream license where the original is canonical.

If you're a researcher, a journalist, or a fellow developer wondering what you can do with material you find inside WAVOA — start here, then use the contact formif anything below isn't clear.

WAVOA app & website

The WAVOA mobile apps (iOS, Android), the WAVOA website (wavoa.app), and every original asset they ship — code, layouts, copy, sport-aware color thresholds, the meteogram chart styling, the firing-rail rating logic, the globe's sport-tier markers, our logo, brand mark, and product screenshots — are © WAVOA SAS 2026, all rights reserved. Your right to use them is a personal, non-transferable, non-exclusive license granted under the Terms of service.

Specifically, you may notredistribute, sublicense, or rebrand WAVOA forecasts; reverse-engineer the apps beyond what EU Directive 2009/24/EC Article 6 explicitly permits; scrape our forecast API; or use WAVOA outputs to train a competing forecasting model. Personal, non-commercial use of the app and the website's public pages is welcome.

Forecast model data

Every wind, gust, wave, swell, period, temperature and tide value WAVOA shows comes from one of four numerical weather prediction models, served end-to-end without field-mixing. We re-host the GRIB outputs internally for performance, but never modify the model fields themselves.

• ECMWF — High-Resolution Forecast (HRES). © European Centre for Medium-Range Weather Forecasts. Used under our ECMWF data license. ECMWF model data is governed by ecmwf.int/en/terms-use; redistribution requires their written consent.
• NOAA — GFS (Global Forecast System) and HRRR (High-Resolution Rapid Refresh). United States National Oceanic and Atmospheric Administration. Public domain as a US Federal Government work; attribution requested but not required: noaa.gov/open-data-dissemination.
• DWD — ICON-D2 and ICON-EU. © Deutscher Wetterdienst. Model output is provided under a CC BY 4.0 attribution license: dwd.de/opendata.
• Météo-France — AROME (selected coastal grids). © Météo-France, used under the French Open License 2.0: meteo.data.gouv.fr.

Wind data on a given screen is always from onemodel — the one labelled at the top-right of the meteogram. We never blend models on the NOW card; the “spread” visualisation in Compare is the closest we get, and it explicitly shows each model as a separate trace.

Map data & basemaps

• MapLibre GL JS — the rendering engine for the live spots map. BSD 3-Clause license: maplibre.org. Source: github.com/maplibre/maplibre-gl-js.
• Carto — “Dark Matter” basemap — the dark map style under the spots map. Style published under MIT, served from basemaps.cartocdn.com. © Carto / © OpenStreetMap contributors: carto.com/basemaps.
• OpenStreetMap data — the underlying tile geometry on the Carto basemap. Open Database License (ODbL); © OpenStreetMap contributors: openstreetmap.org/copyright.
• NASA Blue Marble (Next Generation) — the satellite Earth texture wrapped onto the hero globe and the “sport-aware globe” teaser on the features page. Public domain (NASA Goddard Space Flight Center / Reto Stöckli): visibleearth.nasa.gov/collection/1484/blue-marble.
• Earth topology bump map — derived from NASA SRTM elevation data, public domain: jpl.nasa.gov/srtm.

Open-source software

The website you're reading is built on the libraries below. The full transitive dependency graph (including indirect deps and exact versions) lives in package-lock.json on GitHub; running npx license-checker --production against this repo regenerates a complete machine-readable SBOM.

The mobile apps depend on additional libraries; their full SBOM ships inside the app under Profile → About → Open-source licenses, generated at every build.
