Privacy Policy
Information We Collect
PlainAir does not require user registration or collect personal information directly. We use third-party analytics and advertising services that may collect certain information automatically.
Analytics
We use privacy-focused analytics (Umami) and Google Analytics 4 to understand how visitors use our site. This includes anonymous data such as pages visited, time spent on pages, browser type, and general geographic region.
Advertising
We use Google AdSense to display advertisements. Google may use cookies and similar technologies to serve ads based on your visits to this site and other sites. Learn more at Google's Privacy & Terms.
Cookies
This site uses cookies for analytics and advertising. You can manage preferences through your browser settings. In the European Economic Area, we obtain consent before setting non-essential cookies.
Editorial Independence
Content on PlainAir is compiled by our editorial team: raw EPA air quality data is transformed into readable profiles by our continuous editorial pipeline, validated against the source before publication. The PlainAir editorial team is responsible for editorial standards and corrections.
We do not accept payment, sponsorship, or promoted placement from government agencies, environmental organizations, or any other covered entity. Our only revenue source is contextual display advertising served by Google AdSense, advertisers do not influence which areas or data we cover, and they do not receive preferential placement.
Your Rights
Depending on your jurisdiction, you may have the right to access, correct, or delete your personal data. For California residents, we respect your rights under the CCPA.
