Terms of Use

These terms apply to everyone who uses stashgrid.site and its tools. Using the site means you accept them.

Last updated: September 10, 2026

1. Acceptance

By accessing stashgrid.site or any tool hosted on it, you agree to these Terms of Use and to the Privacy Policy and Disclaimer. If you do not agree, please do not use the site.

2. What StashGrid provides

StashGrid provides free, browser-based calculators and utilities. No account is required and no fee is charged. Tools may be added, changed, or withdrawn at any time without notice, and the site may be unavailable during maintenance or for reasons outside its control.

3. Permitted use

You may use the tools for personal or commercial purposes, and you may use the results they produce however you wish. Results are yours.

You may not:

• Scrape, crawl at abusive rates, or systematically download the site's pages or data files.
• Copy the tools' code or content in order to republish them as a competing product or service.
• Frame, mirror, or present the tools as your own.
• Attempt to interfere with the site's operation, security, or availability.
• Use the site for anything unlawful.

If you would like to embed or reference a tool, use the contact page and ask — permission is usually straightforward.

4. Accuracy and no warranty

The tools are provided "as is" and "as available", without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, or non-infringement.

Considerable effort goes into keeping formulas and reference data correct, and tools are checked against standard formulas and sample scenarios. Even so, calculations may contain errors, reference data such as tax tables may become out of date, and external data sources may be unavailable or wrong. No guarantee is made that any result is accurate, current, or suitable for your circumstances.

5. Not professional advice

Nothing on StashGrid is financial, tax, legal, medical, or investment advice. See the Disclaimer for the detail. Verify anything important with a qualified professional before acting on it.

6. Limitation of liability

To the fullest extent permitted by law, StashGrid and its operator are not liable for any direct, indirect, incidental, consequential, or special damages arising from your use of the site or reliance on any result it produces. This includes financial loss, lost profits, lost data, or decisions made on the basis of a calculation.

Some jurisdictions do not allow the exclusion of certain warranties or limitations of liability, so parts of this section may not apply to you.

7. Third-party links, advertising and affiliate relationships

The site displays third-party advertising and links to third-party websites. Some links are affiliate or referral links, meaning StashGrid may receive a commission if you sign up or make a purchase through them. Affiliate relationships are disclosed on the pages where such links appear.

An advertisement or link is not an endorsement. StashGrid does not control third-party sites and is not responsible for their content, products, pricing, or practices.

8. Intellectual property

The StashGrid name, layout, written content, and tool implementations are the property of the site's operator. The underlying mathematical formulas and public reference data used by the tools are not claimed as proprietary. Third-party trademarks mentioned on the site remain the property of their owners and are used for identification only.

9. Changes to these terms

These terms may be revised. The "last updated" date above reflects the current version, and continued use of the site after a revision means you accept the revised terms.

10. Governing law

These terms are governed by the laws of the State of North Carolina, United States, without regard to its conflict-of-law provisions.

11. Contact

Questions about these terms can be sent through the contact form.
