Background location: Not requested — only needed once continuous exposure tracking exists.
Privacy & Data
You control what is stored and for how long.
AirReach treats location history as sensitive personal information. It is stored against your account only, is never shared with other users without your explicit authorization, and map browsing is never recorded as exposure.
Sign in to see, export or delete stored exposure history.
Data retention: exposure samples and daily segments stay until you delete them or delete your account. Air quality readings themselves are cached briefly (about 15 minutes) and are not linked to you unless a sample references them.
AirReach Sensors
