Privacy Policy — What We Collect (and Don't)

What Pool Heater Calculator collects (almost nothing), what stays in your browser, how calculators remember your inputs, and third-party services used.

Last updated: 2026-10-31

The short version

The calculators on this site run entirely in your browser. The numbers you type — pool size, temperatures, fuel prices — are not transmitted to us, not stored on any server, and disappear when you close the page. We have no accounts, no logins and no newsletter.

What we collect

Usage analytics. If analytics is enabled, we use Google Analytics 4 with IP anonymization to count page views and interactions in aggregate — which pages are used, not what you typed into them.
Local storage. Your theme preference (light/dark) is saved in your browser's local storage. It never leaves your device.
Server logs. Like any website, our host records standard technical request data (IP address, user agent, timestamp) for security and abuse prevention. We do not use it to profile visitors.

Sharing links and embeds

The Share button on a calculator copies a URL that contains your calculator inputs (pool dimensions, prices and so on) so the recipient sees the same result. That link is only created when you click Share — nothing is uploaded in advance. The Embed button gives site owners iframe code for the calculators; embedded tools behave identically and never receive data from the host page.

Third-party services

Google Analytics 4 — aggregate usage measurement, governed by Google's privacy policy.
Advertising. If and when advertising is enabled, ads are served by third-party networks that may use cookies for frequency capping and fraud prevention. This policy will be updated with the specific networks before any ad runs.
Outbound links. Retail or manufacturer links may be affiliate links, marked as such on the page. They carry the third party's own privacy practices.

Your choices

Any modern browser blocks or clears cookies and local storage on request. Refusing analytics cookies does not break any calculator — all tools work fully with everything blocked.
