Terms & Conditions
Please read these terms carefully before utilizing the HazeMY platform, data feeds, or route-level risk scoring tools.
HazeMY is an independent guide. Its forecasts, risk scores, route rankings and heat map do not supersede or replace official statutory advisories issued by the Department of Environment Malaysia (DOE / APIMS), the Malaysian Meteorological Department (METMalaysia), the National Disaster Management Agency (NADMA) or the Ministry of Health Malaysia (MOH).
1. Acceptance of Terms
By accessing or using the HazeMY website, API proxies or commuter calculation services, you agree to be bound by these Terms and Conditions. If you disagree with any part of these terms, please discontinue using the service immediately.
2. Nature of Forecasts and Scientific Accuracy
The 3-hour PM2.5 forecast (an XGBoost model) learns from past CAMS model data and weather. It was tested on four months it had never seen (R² 0.707), but air can change quickly and locally:
- Forecasts are probabilistic projections, not guarantees of localized air safety.
- If the live station feed is down, the site shows sample data and labels it as a sample.
- Vulnerable populations (asthma, COPD, cardiovascular conditions, elderly, pregnant individuals, children) should exercise clinical caution and consult medical professionals.
3. Data Sources & Attribution
HazeMY uses these sources:
- Department of Environment Malaysia station data, through the World Air Quality Index (WAQI) project
- Copernicus Atmosphere Monitoring Service (CAMS) and weather forecasts, through Open-Meteo
- NASA FIRMS satellite fire detections
- OpenStreetMap, OSRM, Photon and Nominatim for maps, routes and place search
All respective trademarks, sensor readings and raw monitoring feeds remain the property of their originating organizations.
4. Limitation of Liability
To the maximum extent permitted by Malaysian law, HazeMY, its authors and contributors shall not be liable for any direct, indirect, incidental, consequential or exemplary damages arising out of your access to or inability to access this service, reliance on route rankings or exposure decisions made based on this platform.
5. Governing Law
These terms shall be governed by and construed in accordance with the laws of Malaysia, without regard to its conflict of law provisions.
