How the SunLah app handles your information and where its weather, air-quality, and mobility data come from.
This app helps visitors to Singapore see local weather, UV, air quality, and getting-around information. We aim to collect as little personal data as possible — the core features work without an account.
This policy explains what limited data the app uses, how it is handled, and the public data sources that power the app.
The app is designed to be privacy-light. Depending on the features you use, it may process:
We do not require your name, email, or a user account to use the core features.
Location is used only to determine which weather area applies to you and to show nearby available taxis. You can deny or revoke location permission at any time in your device settings; the app will then ask you to pick an area manually.
Location is processed to deliver the feature you requested and is not sold or used to build advertising profiles.
If you opt in, the app may send alerts about incoming rain, high UV, or elevated haze levels. These are generated from public environmental data. You can turn notifications off at any time in the app's settings or your device settings.
Weather, air-quality, UV, traffic, and carpark information is sourced from Singapore's open government data platform.
"Contains information from data.gov.sg accessed under the Singapore Open Data Licence. This application is not affiliated with or endorsed by the Government of Singapore."
The data is provided under the Singapore Open Data Licence, which permits use, including for commercial applications. Use of the underlying APIs may also be subject to the providers' own terms. For the licence and source datasets, see data.gov.sg.
Weather, air-quality, taxi, and traffic information is provided "as is" from government sources and may be delayed, incomplete, or temporarily unavailable. It is intended for general guidance and should not be relied on for safety-critical decisions. The app and its operators are not liable for decisions made based on this information.
This policy may be updated from time to time. Material changes will be reflected by the "last updated" date above.
