Privacy Policy - BadAirDays

What this site collects

BadAirDays needs no account and collects no personal information to show a county's record. The county search runs in your browser; what you type is not sent to us. Hosting and analytics infrastructure logs standard technical data (IP address, browser type, pages visited, timestamps) for security and aggregate traffic measurement, and that data is not used to identify you.

Cookies

Analytics cookies may be set to tell repeat visits from new ones. If display advertising from Google AdSense is added, Google may set cookies to serve and personalize ads; see Google's own advertising and privacy policies for how that works.

Advertising and affiliate links

No affiliate relationship is live on this site today. If one goes live, for example a link to an air purifier, furnace filters or an HVAC quote service, this paragraph and the affected page's disclosure line change together, so a paid relationship never appears silently. A commission would never change a county's figures, or the advice that a filter does nothing for ozone.

Third parties

Air quality data comes from the EPA, a public agency; no personal data is exchanged with it. Hosting is provided by Firebase (Google). No data collected here is sold.

Your rights and choices

Depending on where you live you may have rights over the limited data described above, for example under California's CCPA/CPRA, other US state privacy laws, or GDPR for EU and UK visitors: to know what is collected, to ask for its deletion, and to opt out of its "sale" or "sharing" for targeted advertising. To make a request, email hello@badairdays.com.

Google's ad-personalization controls are at adssettings.google.com; industry opt-out tools are at optout.aboutads.info.

Children

This site is not directed at children under 13 and does not knowingly collect information from them.
