Privacy policy

PoolStops publishes free pool-chemistry calculators and route guides. We do not ask you to create an account and we do not sell data.

Calculator inputs

Every calculator on this site runs in your browser. Pool volumes, test readings and dosages you type stay on your device — they are never sent to a server and never stored by us.

Analytics

We use Google Analytics 4 (measurement id G-9PSPNPXR2F) to count page views and see which guides are useful. It sets first-party cookies in your browser (_ga and _ga_9PSPNPXR2F) to tell one visit from the next. We also use Vercel Analytics, which records page views without cookies.

We do not run advertising on this site and we do not sell or share analytics data. You can block both scripts with any content blocker, or refuse the cookies in your browser's cookie settings, and every calculator still works. Your browser's Do Not Track setting is not an opt-out here: Google says most sites and services, its own included, do not change their behaviour when they receive that signal.

Sponsored content

Some articles and vendor listings on this site are paid placements. Payment buys presence, never the page’s verdict or a vendor’s ranking, and every vendor claim is checked against the vendor’s own documentation before it is published. A sponsor never sees anything about you.
