HazeMY privacy policy
Effective date: 1 November 2026
HazeMY is an Android app made by Celestara Sdn. Bhd. ("Celestara", "we"), a company registered in Malaysia. This policy explains what the app does with information about you. It applies to the HazeMY app only, not to Celestara's other services.
The short version: HazeMY has no accounts, no ads, no analytics and no tracking. Your location stays on your phone. We do not collect, store or sell personal data.
Your location
If you allow it, HazeMY uses your phone's approximate location (not precise GPS) to find the nearest town and show its haze level, forecast and weather. This happens on your phone. Your location is not sent to Celestara or to anyone else.
When the app asks for the current weather, it sends the coordinates of the town it is showing, not your own position. That is the town you chose, or, if you use "Use my location", the nearest town in the app's list.
You can use HazeMY without sharing your location: choose a town by hand instead. You can turn location access off at any time in your phone's settings.
What is stored on your phone
The app keeps a few things on your phone so it works offline and remembers your choices: your chosen towns and favourites, your language, notification settings, flood spots you add or remove, and the latest haze, weather and flood data. None of this leaves your phone. Uninstalling the app deletes it.
Who the app connects to
To show current data, the app downloads it from these services:
| Service | What the app downloads | What the service receives |
|---|---|---|
| GitHub Pages (GitHub, Inc.) | Haze, wind and flood data files published by Celestara | Your IP address and app version |
| Supabase | Smoke-path data from NOAA, published by Celestara | Your IP address and app version |
| MET Norway | Current temperature and humidity for the town the app is showing | Your IP address, that town's coordinates, the app name and version |
Like any website, these services see your phone's IP address when the app connects. Each handles it under its own privacy policy. Celestara does not receive these connection records, and none of the requests includes your phone's own position, a device ID, an advertising ID or an account. The flood map's roads are stored in the app, so the app does not fetch map tiles.
Notifications
HazeMY can show an ongoing notification with the haze level, MetMalaysia thunderstorm warnings, and heavy-rain warnings for roads you choose to watch. These are created on your phone from the downloaded data. You can turn them off in the app's settings or in your phone's settings.
Children
HazeMY is a general-audience app and is not directed at children under 13. It collects no personal data from anyone, including children.
Your rights
Celestara follows Malaysia's Personal Data Protection Act 2010. Because the app sends us no personal data, we hold none about you to access, correct or delete. If you have a question or a concern about this policy, email us and we will reply.
Changes to this policy
If a future version of HazeMY changes what it does with information about you, we will update this page before that version is released and change the effective date above.
