2. Third-Party Components & Data
SkyWX relies on components and data that are not owned by
skyWX.app and remain the property of their respective owners, used under
their own terms:
This notice claims no ownership over any of the above. All trademarks and
data belong to their respective owners.
3. Terms of Use
SkyWX is provided for general informational and educational purposes.
By using SkyWX you agree to use it lawfully and not to misuse, overload,
scrape at scale, or attempt to disrupt the service or its data providers.
SkyWX runs in your browser. Your settings are stored only on your own
device; SkyWX does not collect, transmit, or sell your personal data. Live
data is fetched directly from the third-party providers listed above when you
use the app.
4. Accuracy & "As-Is" Disclaimer
All values shown by SkyWX — including sun and moon times, twilight phases,
space-weather indices, aurora forecasts, satellite positions, and solar PV-yield
estimates — are approximations for general guidance only.
They may contain errors or be delayed, and depend on third-party data that may
be inaccurate or unavailable.
SkyWX is provided "as is" and "as available",
without warranties of any kind, express or implied, including but not limited to
accuracy, fitness for a particular purpose, or uninterrupted availability.
Do not rely on SkyWX for any safety-critical, navigational,
aviation, maritime, financial, or operational decision. Solar PV-yield figures
are planning estimates only and are not a guarantee of real-world output; verify
against professional assessments and actual equipment specifications before any
purchase or installation decision.
5. Limitation of Liability
To the fullest extent permitted by law, skyWX.app shall not be liable for
any loss or damage of any kind arising from the use of, or reliance on, SkyWX or
its data, whether direct, indirect, incidental, or consequential.
6. Contact
For permissions, licensing, or copyright enquiries regarding SkyWX, contact the
owner via skywx.app.
SkyWX is a live sky & solar dashboard. In one place it shows the real-time
state of the sky for your location: moon phase, sunrise, sunset and twilight,
space weather (Kp index, solar activity, aurora forecast), an interactive 3D Earth
globe with satellites overhead, and a solar PV-yield estimator that uses live
irradiance to project how much energy a panel array would produce.
How it works
SkyWX runs entirely in your browser — there is no account and no server holding
your data. Sun, moon and twilight values are computed locally on your device.
Live data is fetched directly from public providers when you use the app, and your
settings are saved only on your own device.
Data & sources
• Sun, moon & twilight — computed locally on your device.
• Space weather — NOAA SWPC (Space Weather Prediction Center).
• Irradiance & cloud — Open-Meteo.
• 3D globe rendering — Three.js (MIT).
Accuracy
All values are approximations for general guidance only and depend on third-party
data that may be delayed or unavailable. Do not rely on SkyWX for safety-critical
decisions. PV-yield figures are planning estimates, not guarantees.
