Terms, privacy & accessibility

This manual is offered free, as general education. In plain language: use it at your own risk, we collect nothing about you, and we try to make it usable by everyone. The details follow. Last updated October 31, 2026.

1. Terms of use and disclaimer

By using this site you agree to these terms. If you do not agree, please do not use it.

Educational content only

Everything here is general information, written for hobbyists and self-taught beginners. It is not professional, medical, legal, financial, engineering or safety advice, and it is not a substitute for the judgment of a qualified professional for your specific situation. Materials, sites, climates and people vary; results will differ from what is described.

Personalized content

The "Your home" boxes, calendar, dates and calculator are generated automatically from what you type into the setup form, using general rules of thumb. They are planning estimates, not guarantees. Check every number against your own tests and your suppliers.

Safety

• Never mix cleaners. Never mix bleach with ammonia or with acids such as vinegar. Read every cleaner's label and use it as directed.
• Test first. Test any cleaner on a hidden spot first, and follow your product's care sheet over this manual.
• Old flooring. Do not sand, scrape, power-strip or remove old floor tiles, sheet vinyl, adhesive or textured finishes until an accredited inspector has checked them. You cannot tell asbestos by looking.
• Lead paint. In a home built before 1978, painted woodwork and cabinets may contain lead. Do not sand or scrape them without lead-safe steps, and hire a certified contractor for work you pay for.
• Stone dust. Do not cut, grind or drill engineered stone, natural stone or tile yourself. The dust can contain crystalline silica.
• Falls. Wet and polished floors are slippery. Secure or remove loose rugs, and use non-slip mats or strips where someone at risk of falling bathes or walks.
• Moisture. Water under a floor, a musty smell or cupping boards point to a moisture problem. Call an inspector or restoration professional.
• Ratings and warranties. Ratings, labels and warranties describe set tests and contracts. They do not promise how a surface will wear in your home.
• Radon. Test your home for radon. A countertop is not a radon test.
• No professional advice. This manual does not give legal, medical, structural or financial advice. Your records stay in this browser unless you export or share them.

Third-party links and products

The site links to tutorials, suppliers, books and other resources we found useful. We do not control those sites, do not endorse or guarantee anything on them, receive no payment or commission from them, and are not responsible for their content, availability, accuracy or practices. Product and brand names mentioned belong to their respective owners and are used only to identify them.

No warranty; limitation of liability

The site and its content are provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, completeness, fitness for a particular purpose and non-infringement. To the fullest extent permitted by law, Field Assembly LLC, Reassembly and the people who made this site are not liable for any loss, injury or damage, direct or indirect, arising from your use of the site or reliance on its content. Some jurisdictions do not allow certain limitations, so some of this may not apply to you.

Governing law

These terms are governed by the laws of the Commonwealth of Massachusetts, without regard to its conflict-of-law rules. Any dispute arising from the site or these terms will be brought in the state or federal courts located in Massachusetts, and you consent to their jurisdiction.

Changes and availability

We may change, pause or remove the site or any part of it at any time without notice. We have no obligation to keep it available or up to date.

2. Privacy

Short version: this site does not collect, store or sell any information about you. If you choose to email us, we receive your address and your message.

• No accounts, no sign-up. You never need to give us an email address to use the pages. There is nothing to join.
• No analytics, no tracking, no advertising, no cookies. The site sets no cookies and includes no third-party scripts, pixels or embedded content. Fonts are served from this site, not from a font service.
• Your setup stays on your device. What you type into the setup form, and the progress checkboxes, are saved only in your browser's local storage so the site can show them back to you. They are never transmitted to us. Clearing your browser data, or using the "Clear my setup" button, deletes them.
• Share links contain your setup. The "copy a link" feature encodes your answers into the web address itself so you can open them on another device or send them to a helper. Anyone who has that link can see those answers. Do not put anything in the setup form that you would not want in a link you share.
• If you email us, we use your address only to reply, and we do not add it to any list.
• Hosting logs. The site is hosted on Cloudflare, which, like any web host, processes technical request data (such as your IP address, browser type and the pages requested) to deliver the site and protect it from abuse, under Cloudflare's privacy policy. We do not use that data to identify or track visitors.
• Links to other sites take you to services with their own privacy practices.
• Children. The site is not directed at children under 13 and we knowingly collect no information from anyone.

3. Accessibility

We want this manual to be usable by everyone, including people who use screen readers, keyboards, magnification or high contrast. The site is built to follow the Web Content Accessibility Guidelines (WCAG) 2.1 at level AA. Specifically:

• Semantic HTML with headings, landmarks, lists and tables with header rows; a "skip to content" link; visible keyboard focus on every control.
• Every form field has a label; checkboxes and radio buttons are labeled; the menu button reports its state.
• Text and interface colors meet contrast minimums in both light and dark modes; information is never conveyed by color alone.
• Text resizes with browser settings, and the Text size control in the menu makes it larger on every page (saved in this browser only); layouts reflow to narrow screens; no content flashes or moves on its own.
• Buttons, checkboxes, form fields and menu items are at least 44 pixels tall, so they are easy to tap.
• Diagrams have text descriptions; icons in the navigation are decorative and accompanied by text.

Known limitations: wide reference tables scroll horizontally on small screens, and printable pages depend on your browser's print settings. If anything on this site is hard for you to use, please tell us through fieldassembly.net and we will try to fix it.
