Terms of use

The rules for using KitPine.

Updated October 19, 2026

Using the site

KitPine is free to use for personal and commercial projects. You do not need an account.

Results are estimates

Results are calculated from the numbers you enter and from typical values that we list on each page. They are meant for planning and shopping, not as professional advice.

Before you buy materials or start work, check the product label, the manufacturer’s instructions and the building rules where you live. Structural work, stairs, roofs and anything that needs a permit should be checked by a qualified professional.

No warranty

We work to keep every formula and figure correct and we fix mistakes when they are reported, but the site is provided as is, without warranties of any kind. To the extent the law allows, we are not liable for losses arising from the use of the site or its results.

Content and links

The text, design and code of KitPine belong to us. You may link to any page and quote short passages with a link back. Links to other websites are provided for reference; we do not control their content.

Advertising

Ads on KitPine are provided by Google. The privacy policy explains how advertising cookies are used.
