By using www.lanhometech.com you agree to these terms. If you don't agree, please don't use the site.
Use of our tools
Our calculators are free to use for personal and professional project planning. You may not scrape, resell or misrepresent the tools as your own, but you're welcome to link to them and share your results.
Estimates are for planning only
This is the important part. Every quantity and cost figure our tools produce is a planning estimate based on standard formulas and typical values. It is not a guarantee, a bid, or professional advice. Actual material needs and costs depend on a field measurement, your specific products, local pricing, site conditions, and manufacturer installation requirements. Always confirm with a qualified contractor and your supplier before ordering or committing funds.
No warranty
The site is provided "as is" without warranties of any kind. We work to keep our defaults reasonable and our math correct, but we don't warrant that results are error-free or suitable for a particular purpose.
Limitation of liability
To the fullest extent permitted by law, LanHomeTech is not liable for any loss arising from reliance on our estimates, including over- or under-ordering of materials or budget shortfalls. You are responsible for verifying quantities and costs.
Links and ads
We may link to third-party sites and display advertising. We are not responsible for the content or practices of third parties.
Changes
We may revise these terms; continued use after changes means you accept them.
