Terms & disclaimer

Last updated: 27 August 2026.

Estimates, not advice

All calculators and content on ConcreteTally (https://concretetally.com) provide estimates for general information only. Nothing on this site is construction, engineering, safety, or other professional advice, and nothing here creates any advisory or client relationship. Material specifications differ between suppliers and site conditions differ between jobs; before you buy or build, confirm quantities with your supplier and follow the product's own label and your local building code.

Chemical products

Where a calculator estimates a dose of a pool or treatment chemical, the product's own label is the legal authority on how it may be used. Those labels are federally approved, and the directions on them override any figure shown here. Each calculator that estimates a dose carries the safety wording it is quoting, with the label it came from — this page does not add handling instructions of its own.

No warranty

The site is provided "as is". While every figure is sourced from published manufacturer or standards documents and tested against them, we make no warranty that results are accurate, complete, or current for your situation, and accept no liability for decisions made on the basis of the site's output, to the fullest extent permitted by law. Nothing in these terms limits liability that cannot lawfully be excluded.

Acceptable use

You may use the calculators for personal and internal business purposes. You may embed a calculator using the provided embed pages, provided the attribution link remains visible and unmodified. You may not scrape, republish, or misrepresent the site's content as a manufacturer's, a standards body's, or a government resource.

Intellectual property

Site content, design and code are © 2026 ConcreteTally unless otherwise stated. Published specifications belong to their publishers and are cited; their presentation and the calculator implementations are ours.

Changes

These terms may be updated from time to time; the date above reflects the latest revision. Continued use after a change constitutes acceptance.
