Your Privacy Matters

Effective date: November 6, 2026

AirAndWater.win is free to use

You do not need to create an account or give us your name, email address or payment information to search a place or read air- and water-quality information.

Information you choose to send

If you email us, we receive the information you include, normally your email address and your message. Please do not send passwords, payment details, government identification numbers, medical records or other sensitive information; we do not need them to answer an ordinary question.

Your location

Approximate city. To start you with useful results, the search box may be filled in with the approximate city associated with your internet connection, as determined by our hosting provider, Cloudflare. We use it only to pre-fill the search box; you can change it at any time, and we do not store it.

Precise location (optional). If you choose “Use my location”, your browser will ask for your permission. If you allow it, your coordinates are rounded (to roughly one kilometre) and used once to find the nearest U.S. ZIP code area. They are not stored. You can decline, and you can change this permission in your browser settings at any time.

Searches. To answer a search, our service looks up public data: the place you enter (a U.S. city or ZIP code area) may be used to request records from U.S. government services, including the U.S. Environmental Protection Agency (ECHO / Safe Drinking Water Information System) and the U.S. Census Bureau Geocoder, and to read air-quality files published by EPA AirNow. These requests contain the place, not your name or contact details.

The technical side of a visit

For a website to reach your device, some technical information travels with each request, such as your IP address, browser and device information, the pages requested, the date and time, and diagnostic or security information. AirAndWater.win and the services that deliver and protect it may process this information to show pages, keep the site secure and diagnose problems.

Services that help us run the site

Cloudflare hosts and protects AirAndWater.win and may process network, request and security information, and may use strictly necessary security cookies, in accordance with Cloudflare’s own privacy practices.

Google Fonts. Our pages currently load the Nunito typeface from Google Fonts, so your browser contacts Google’s servers to download it. Google may receive your IP address and browser information as part of that request.

Google advertising

AirAndWater.win uses Google AdSense to show advertising, which helps keep the website free. Advertisements are clearly labelled and kept separate from our air- and water-quality information; advertising never changes the readings, records or explanations we display. Advertisements may not appear on every page or visit.

When a page with advertising loads, your browser communicates with Google, and Google may receive information such as the page address and your IP address. Google and its advertising partners may use cookies, web beacons or similar technologies to deliver and measure advertising, prevent fraud and, depending on your settings and location, personalize ads. We do not load advertising on our Privacy, Terms or Contact pages.

Your advertising and cookie choices

Where the law requires it (for example in the European Economic Area, the United Kingdom and Switzerland), you will be asked for consent through Google’s consent message before personalized advertising or non-essential cookies are used, and you can change your choice at any time. You can manage ad personalization through Google My Ad Center ↗ and read how Google uses information from sites that use its services ↗. Your browser also offers settings to block or delete cookies.

Analytics

AirAndWater.win does not currently use analytics trackers. If we add analytics, we will update this page first.

When you follow a link elsewhere

We link to government agencies, water utilities and other organizations. Their own privacy policies and practices apply once you visit their websites.

For everyone, including children

AirAndWater.win is a general information resource for people of all ages. Its tools do not require an account, and they are not designed to collect personal information from children.

Questions about privacy

If something on this page is unclear, please write to [email protected] with “Privacy” in the subject line.

If the way we operate changes, this page will change too

Websites, services and rules evolve. If the way AirAndWater.win handles information materially changes, we will update this page so that it always describes how the site actually works.
