Terms of Service

Last updated: September 12, 2026

Using this site

Pool Sums provides free dog and cat calculators for educational and informational use. No account or sign-up is required, and there is no charge to use any page on this site.

Not medical advice

The calculations on this site use standard, published references (university extension seeding and fertilizer rates, industry pool-chemistry dosing figures, manufacturer sizing guidance, geometric volume formulas), not original research or a site-specific recommendation. They are planning estimates. Product labels govern chemical and fertilizer doses; a water test or soil test is the real basis for any treatment. Do not rely on any number here in place of the label.

No warranty

This site is provided "as is," without warranty of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose. Use of any calculator or content on this site is at your own risk.

Limitation of liability

To the fullest extent permitted by law, Pool Sums and its operator are not liable for any loss or damage arising from use of, or reliance on, this site or its content.

Advertising

This site may display ads served by Google AdSense and other third-party advertising networks. See the Privacy Policy for details on how those networks use cookies and similar technologies.

Content

The text, design, and code on this site belong to Pool Sums unless otherwise noted. You're welcome to link to any page here; please don't republish or scrape the content wholesale without permission.

Changes

These terms may be updated from time to time. Continued use of the site after a change means you accept the updated terms.
