Terms of use

Using the tools

All tools are free for personal and commercial use. Do not try to disrupt the site, overload our servers or use the tools for anything illegal.

Accuracy

We work hard to keep every formula and rate correct, but results are estimates. For tax, legal, medical, financial or admission decisions, confirm the figures with the official body or a qualified professional.

Content you download

Files you create with our tools belong to you. YouTube thumbnails belong to their creators, so only use them in ways the owner allows.

Liability

The site is provided "as is". MasterKit Online is not liable for losses that come from using the tools or relying on their results.

Changes

We may update these terms. The date at the top shows the latest version.
