Terms of Service

Last updated: July 2026

Acceptance of terms

By using Reckon, you agree to these terms. If you don't agree, please don't use the site.

Description of service

Reckon provides free, browser-based calculators and unit converters. There are no accounts, subscriptions, or fees — every tool is free to use.

Not professional advice

Reckon's tools are intended for general, informational, and educational use only. In particular:

• The BMI Calculator is a general screening tool, not a medical diagnosis — consult a healthcare professional for advice about your health.
• The Patio Calculator gives estimated material quantities only — verify measurements and consult a professional before purchasing materials or beginning construction.
• The Ring Size Converter provides an approximate match against a standard sizing chart — actual fit varies between jewelers and manufacturers.
• All other calculators and converters are provided for general convenience and should be independently verified for anything important (financial, legal, medical, or safety-critical decisions).

Accuracy

We aim for every calculation to be correct, and each formula is based on standard, publicly documented conversion factors and formulas. That said, Reckon is provided "as is" without warranty of any kind, and we don't guarantee the tools are error-free, uninterrupted, or fit for any particular purpose.

Acceptable use

Please don't attempt to disrupt the site, scrape it at abusive volume, or use it for any unlawful purpose.

Intellectual property

The design, branding, and code that make up Reckon belong to Nootan Labs. You're welcome to use the tools themselves for personal or professional purposes, but please don't copy or republish the site's design or code as your own.

Third-party links and services

Reckon may link to or load resources from third-party services (such as Google Fonts, Font Awesome, Google Analytics, or Google AdSense). We aren't responsible for the content, accuracy, or practices of any third-party service.

Limitation of liability

To the fullest extent permitted by law, Nootan Labs and Reckon are not liable for any damages or losses arising from your use of, or inability to use, this site or its calculations.

Changes to these terms

We may update these terms from time to time. Continued use of the site after changes means you accept the updated terms.
