Terms of use

Free to use

The tools are free for personal and commercial projects. Plans, charts and files you create with them are yours to use, share and print.

Your content

You are responsible for the pictures and designs you load into the tools, and for having the right to use them. Because everything runs on your device, we do not receive or store them.

Acceptable use

Do not use the site to break the law, to attack or overload the service, or to copy the site and present it as your own.

No warranty

We work hard to keep results accurate, but the tools are provided as they are, without warranties of any kind. Check important measurements and quantities before you buy materials or start a large build.

Limitation of liability

To the extent the law allows, GridTools is not liable for any loss or damage arising from use of the site or its results.

Trademarks

Product and brand names belong to their owners and are used only to describe compatibility. See the disclaimer.

Changes

We may update these terms. Continued use after an update means you accept the new terms.
