Terms of use

Last updated: 9 October 2026

The deal

Plain Sums is run by Arthur Jones. The calculators are free to use. By using the site you agree to these terms.

As is

Everything is provided as it is, with no warranty of any kind. Calculators and pages may change, break or be taken down at any time. The calculators give estimates, not tax, legal or financial advice: see the disclaimer.

Liability

As far as the law allows, I'm not liable for any loss or damage from using the site or relying on anything on it. Nothing here limits liability that can't legally be limited, such as for death or personal injury caused by negligence, or fraud.

Templates

Templates are sold and delivered by Gumroad, and Gumroad's terms apply to the purchase.

Fair use

Don't try to break, overload or misuse the site.

Ownership

The content and code on this site are © 2026 Arthur Jones. All rights reserved, unless credited otherwise.

Law

These terms are governed by the law of England and Wales, and its courts have jurisdiction.
