Effective November 4, 2026. Last updated November 4, 2026. Resumen en español.

Nail the Math is published by Albatross Vibe LLC. This page explains what our calculators and guides can and cannot do, and how the Site is funded. It is part of our Terms of Use.

Estimates for planning, not professional advice

Our calculators, tables, guides and data pages give general information and estimates to help you plan a project and buy materials. They are not engineering, architectural, construction, legal, financial or safety advice, and using them does not create a professional relationship with us. Every result depends on the measurements and choices you enter and on the assumptions stated on the page, such as waste allowances, product yields and coverage rates. Real quantities and costs also depend on site conditions, products, workmanship and local practice that we cannot see.

Building codes and safety

Where we quote a building code, energy code or government figure, we cite the edition and source. Codes are adopted, amended and enforced locally and change over time, so the rules that apply to your project may differ. Your local building department has the final say. For anything structural, such as footings, beams, decks, stairs, guards, roofs and retaining walls, and for electrical, plumbing, gas and heating work, confirm the requirements locally and use a licensed professional where required. Follow the manufacturer's instructions for every product, and use appropriate safety equipment.

Accuracy and sources

We work hard to keep the Site accurate: every number comes from a named source, the calculations are tested, and each page shows when it was last reviewed. Our editorial policy describes the process. Even so, sources can contain errors, products and prices change, and we can make mistakes. Prices we quote, such as fuel prices, are historical averages from the stated source and date, not quotes or offers. If you find an error, please tell us.

How AI is used

Pages are drafted with AI writing and research tools, then checked by automated tests, an automated style check, a browser test and a separate review by an AI editor against the source data before publication, within a content plan approved by the site owner. No page is individually reviewed by a person before it goes live. The process is described in our editorial policy.

Advertising

The Site is free. We intend to fund it with advertising through Google AdSense; no ads are shown yet. When ads appear, they will be selected by Google and its partners, not by us, and labeled as advertising. Advertisers do not pay for, review or influence our calculators, results or recommendations. Seeing an ad on the Site is not an endorsement of the advertiser.

Affiliate links

We may add links to retailers where you can buy the materials a calculator lists. Some of these may be affiliate links, which means we may earn a commission if you buy through them. The commission does not change the price you pay. Affiliate relationships never change a calculator's result or a recommendation in a guide, and we choose links based on the materials a project needs, not on commission rates. Pages with affiliate links will say so near the links. Where a program requires a specific statement, we will display it; for example, if we join the Amazon Associates program: "As an Amazon Associate we earn from qualifying purchases."

We link to official sources and other websites for your convenience. We do not control them and are not responsible for their content, accuracy, availability or privacy practices.

Pen names

Claire Bennett and Jordan Hale, names you may see on emails from us, are pen names used by the publisher, not real people. The owner of Albatross Vibe LLC approves every email sent under them, and replies to them reach us.
