📍 Our Commitment to GPS & Location Privacy

HazeWatch is engineered from the ground up on strict privacy-first principles. Because our app utilizes location services to find your nearest environmental station, we believe in complete transparency:

100% On-Device Processing Your GPS coordinates (latitude/longitude) are calculated entirely within iOS on your physical device.
Zero Coordinate Transmission Your exact GPS coordinates are NEVER sent to our servers, stored in databases, or logged anywhere.
Only Region Names Queried The app maps coordinates locally to a broad zone (e.g. "West" or "Kuala Lumpur") and only requests public government data for that sector.
No Location History We do not track where you travel, when you move, or where you live. No tracking profiles are ever created.

⚠️ Non-Commercial Public Service Disclaimer
