Privacy policy
Last updated: November 9, 2026
This policy explains what information is collected when you visit https://poolbalancecalc.com (the "site") and how it is used.
Calculators
All calculators run entirely in your browser. The numbers you enter are not sent to us or stored on our servers.
Some links between calculators carry your pool volume or surface area in the web address (for example ?gal=15000), so the next calculator can fill it in. Opening such a link sends that web address to our hosting provider, like any other page request.
Information collected automatically
Like most websites, our hosting provider and analytics tools may collect standard technical information, such as your browser type, device type, approximate location derived from your IP address, referring pages and pages visited. We use this in aggregate to understand which pages are useful and to keep the site running securely.
Cookies and advertising
This site may use Google AdSense to display ads. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this site or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and/or other sites on the Internet.
You can opt out of personalized advertising by visiting Google's Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info. To learn more about how Google uses data, see How Google uses information from sites or apps that use its services.
Visitors from the European Economic Area, the UK and Switzerland will be asked for consent before personalized ads or non-essential cookies are used.
Analytics
We use Cloudflare Web Analytics to count page views and see which pages are useful. It does not use cookies or local storage and does not build profiles of individual visitors. It reports aggregate figures such as page views, referring sites, country and device type.
If we add another analytics service in the future, such as Google Analytics, we will update this policy before doing so.
If you email us, we use your email address only to reply. We do not sell or share it.
Children
This site is not directed at children under 13, and we do not knowingly collect personal information from them.
Your rights
Depending on where you live, you may have rights to access, correct or delete personal information, or to object to certain processing. To make a request, contact us at [email protected].
Changes
We may update this policy from time to time. The date at the top shows when it was last revised.
