Aetherfield does not collect, store, use or share any information about you. There is no account, no analytics, no tracking, no advertising identifier, and no server belonging to this app.

  • Air-quality readings and recorded history are stored only on your device.
  • Local monitors are contacted directly over your own network. That traffic never leaves your home.
  • If you add an AirGradient cloud API token, the app sends it only to AirGradient (api.airgradient.com) to fetch readings for your own locations. Those requests are governed by AirGradient’s privacy policy; nothing is sent anywhere else.
  • The token and your settings are stored on your device.
  • Removing a monitor deletes its recorded history. Deleting the app deletes everything.

Email

If you email me for support or feedback, I’ll use your email address only to reply. I don’t add it to any list, use it for marketing, or share it.

Disclosure

I will not disclose your information to any third party unless you expressly consent, or where required by law.
