We use certain third-party service providers ("subprocessors") to assist in delivering our products and services. These subprocessors may process personal data on our behalf in connection with the services we provide to our customers.

This page lists the subprocessors currently authorized by AirGradient, along with their purpose. We will update this page as our subprocessor list changes.

Public Data Recipients

Public data recipients receive monitor data only when a user or customer enables public sharing or a customer deployment explicitly requires public sharing.

Recipient	Purpose	Data Shared	License or Terms
AirGradient public map and public API users	Public air quality visibility, reuse, research, civic tools, community dashboards	Public monitor measurements, timestamps, selected public coordinates/location metadata, data source, attribution, license metadata	AirGradient public documentation states public API data is CC-BY-SA 4.0
OpenAQ	Open air quality repository and research/community reuse	Public monitor measurements, timestamps, public coordinates/location metadata, source and attribution metadata	AirGradient public documentation states direct OpenAQ sharing is CC-BY 4.0
Other optional public data partners	Public-interest, research, civic, government, or community use where enabled	Public monitor data and public location metadata	Partner-specific terms should be confirmed before enablement

Once public data is shared, third parties may download, cache, republish, analyze, or combine it with other datasets. Disabling public sharing stops future sharing through AirGradient-controlled channels but may not remove data already copied by third parties.

Data Source Providers

AirGradient may use public, partner, or reference data sources to enrich air quality and environmental services.

Examples may include OpenAQ, public air quality networks, wildfire or satellite datasets, geospatial reference datasets, map data, and city or urban-center datasets.
