Your data
We will never share or sell your data.
We will never share your personal data.
We will never sell your personal data.
We use what you give us only to run this site and send the alerts you ask for.
This policy is current as of 21 September 2026.
The promise
We will never share your email, ZIP, or questions with advertisers, data brokers, or anyone buying a list.
We will never sell your email, ZIP, or questions.
We will never rent, trade, or give your personal data to a marketing partner.
What we collect
A ZIP you enter so we can open the matching water system.
An email you type only if you ask to watch a water system or ask about paid work.
A question you send to Clara, used only to answer you.
Anonymous page counts that show which pages people use.
How we use it
A ZIP opens your water system and can stay on this browser so the next visit is faster.
A watch email is stored so we can reach you when that water system needs attention.
A work request email is stored so we can reach the school, clinic, agency, or building that asked.
Clara uses your question only to give you a next step on this site.
Page counts help us see which doors people find.
What we never do
We never share your personal data.
We never sell your personal data.
We never publish your email or your street address.
We never add you to any other list.
We never use advertising cookies.
Cookies on this browser
One cookie can remember the last ZIP you looked up.
One cookie can remember which water systems you asked to watch here.
One cookie can remember which testing-path steps you finished on this browser.
Those cookies stay on your browser and are not a mailing list.
Who else can see a record
The computers that run this site store the same records so a page can load and an alert can send.
That is not a sale.
That is not a share with advertisers or data brokers.
They do not get a right to reuse your data.
What stays public
Official water-system rows cite public reporting.
Sourced news cards link to the original report.
Household samples, when we publish them, snap to a census block group.
Exact street addresses never go public.
The status page may show how many people watch a system, not who they are.
Children
We do not ask a child for an email or other personal data.
A parent, school, or clinic can use this site for a child without creating an account.
When this policy changes
If we add a new use, we will say so on this page.
The rule that we never share or sell your data does not change.
