Terms of Use
By using Chase the Sunset (“the site”) you agree to these terms. If you don’t agree, please don’t use it.
What the site does
The site estimates how vivid a sunset or sunrise is likely to be, using public weather, air quality and airport data and our own model. It is for fun and planning.
Forecasts are estimates
Sky forecasts are uncertain. We give no guarantee that a forecast, score or verdict will be accurate, complete or up to date, and the sky may look nothing like what we predicted.
Stay safe
Don’t use the site to make safety-critical decisions. It is not a weather warning service, a navigation aid or a substitute for official forecasts. If you head out to watch the sky, you’re responsible for your own safety: mind the terrain, tides, traffic, trespass rules, the weather and the dark. Never look directly at the sun.
Acceptable use
Don’t abuse the site: no automated scraping or heavy automated requests, no attempts to disrupt or break into it, and no use that breaks the law. We rely on free third-party data services and may limit access to protect them.
Our content
The site’s design, text, code and model are ours or used under licence. You may share links and screenshots of your own results. Weather data comes from Open-Meteo (CC BY 4.0), air quality from CAMS, airport reports from NOAA, and place data from Open-Meteo, BigDataCloud and © OpenStreetMap contributors.
No warranty, limited liability
The site is provided “as is” and “as available”, without warranties of any kind. To the fullest extent the law allows, we aren’t liable for any loss or damage arising from your use of the site or reliance on a forecast, including a wasted trip. Nothing here limits liability that can’t be limited by law.
Changes and availability
We may change or stop the site, or these terms, at any time. Continued use after a change means you accept it.
Privacy
How we handle data is described in our Privacy Policy.
