Common questions

Where does the air quality data come from?

Readings come from the public air quality monitoring network run by the Department of Environment Malaysia (DOE). mySifu shows the latest readings published by DOE. Stations normally update every hour, and a station may show no reading for a while if it is offline or under maintenance.

Why does mySifu show a different station from the one I expected?

mySifu picks the station closest to your location. To always see a particular station, open it and set it as your default, or add it to your favourites.

Do I need to share my location?

No. Location is only used to find the stations nearest to you, and it stays on your device. If you prefer not to share it, you can choose stations manually. You can change location access at any time in your device settings.

I am not getting AQI alerts. What should I check?

1) Make sure alerts are turned on in mySifu and your alert rules are set. 2) Allow notifications for mySifu in your device settings. 3) Allow background activity: on iPhone, turn on Background App Refresh for mySifu; on Android, turn off battery optimisation for mySifu. 4) Remember that alerts only fire when readings actually cross your threshold, and background checks run periodically rather than in real time.

How do I add the home screen widget?

On iPhone, long-press your home screen, tap the + button, search for mySifu and add the widget. Open the app at least once so the widget has data to show.

How do I delete my data?

mySifu has no account. Most of your data (favourites, alert rules, settings) is stored only on your device and is removed when you uninstall the app. To delete your alert registration from our server, send us a message below with the topic "Privacy / data deletion". See our Privacy Policy for details.
