Privacy
A small amount of usage data, kept separate from the research archive.
Delhi Air Health does not create visitor accounts or collect personal health records. Website analytics and the environmental research archive serve different purposes and are not joined together.
Website analytics
Google Analytics 4 measures how the public site is used.
Analytics records page visits and interactions such as saving a campus preference, changing a campus comparison, using the activity planner, exploring history, and downloading a research file. Event data uses campus or feature labels—not names, email addresses, free-text health information, or account identifiers supplied by Delhi Air Health.
Google may process device, browser, approximate-location, cookie, and usage information under its own terms. Browser privacy controls, tracker blocking, or disabling cookies may prevent measurement without preventing access to the site.
How Google uses information from sites and apps ↗Campus preference
Your selected campus stays in this browser.
The “My campus” setting is stored locally on the device so the homepage can reopen with the same campus. No Delhi Air Health account is created. Clearing the preference in the dashboard or clearing site data in the browser removes it.
Research boundary
Visitor analytics never become study observations.
The prospective study uses publicly available, area-level ambient monitoring data. It does not use website visitor behavior, campus preferences, personal location, or individual health information as research data.
Effective 13 September 2026. This notice will be revised if the site begins collecting materially different information.
