Privacy policy

Last updated November 15, 2026

This policy explains what information CityH2O ("we", "us") collects at cityh2o.com, how we use it, and your choices.

Information you give us

When you submit a form (free water check, Filter Finder, newsletter, contest, careers, support, advertising, pro network or contact), we receive the details you enter — such as name, email, phone, city or postal code and your answers. We use this only to respond to your request, send what you signed up for, administer contests and, only where you ask for it and consent, share your request with up to three certified local professionals.

Forms are delivered to our private inbox through a third-party form-processing service (FormSubmit). We do not sell personal information.

Calculators

Our calculators and the Filter Finder run entirely in your browser. Values you type into them are not sent to us unless you choose to submit a form.

Cookies and advertising

We use a small amount of browser storage to remember preferences (theme, cookie choice). We use Google AdSense to show ads. Google and its partners use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to our site and/or other sites on the internet.

Embedded YouTube videos load only when you click play, using YouTube's privacy-enhanced mode (youtube-nocookie.com). Google Fonts are loaded from Google's servers.

Hosting and logs

The site is hosted on GitHub Pages, which may log IP addresses for security and operations under GitHub's privacy statement.

Retention

We keep form submissions only as long as needed to handle your request and meet legal obligations, then delete them. Newsletter subscribers can unsubscribe at any time.

Your rights

Depending on where you live (for example under the GDPR, UK GDPR, PIPEDA, Québec Law 25 or U.S. state privacy laws such as the CCPA/CPRA), you may have rights to access, correct, delete or port your data and to opt out of certain processing. Make a request through our contact page.

Children

The site is intended for adults. We do not knowingly collect personal information from children under 13 (or under 16 in the EEA). Student contest entries require parent or guardian consent.

Changes

We may update this policy and will change the "last updated" date when we do.
