Terms of Use
Last updated: May 26, 2026.
General use
Toolkit Shelf provides free calculators, generators, checkers, analyzers, guides, and informational content for general use. Results are estimates or draft outputs based on the inputs, formulas, methods, and assumptions shown on the relevant page.
You may use the public pages for personal planning, comparison, learning, drafting, and lightweight internal workflows. The visible formulas, examples, benchmark notes, source links, and templates are part of the informational content and should be checked against your real situation before you rely on them.
Not professional advice
Toolkit Shelf does not provide financial, legal, tax, medical, engineering, accounting, employment, real estate, or other professional advice. You are responsible for checking important calculations, outputs, and assumptions with qualified sources before making decisions.
Pages that mention rates, health estimates, housing costs, business metrics, creator sponsorships, tax-adjacent items, or compliance concepts are still general information. They do not create a client, patient, advisor, contractor, accountant, or attorney relationship.
Accuracy and availability
Toolkit Shelf aims to show formulas, methods, assumptions, examples, and limitations clearly, but the site is provided as is and may contain mistakes, outdated information, interruptions, or missing context. The site may change, add, or remove tools, guides, pages, or features at any time.
Source links can move, third-party pages can change, and public rates or rules can become stale. If you find a broken source, incorrect formula, unclear benchmark, or missing warning, use the contact page to send the page URL, inputs, output, and correction reference.
Third-party references and ads
Toolkit Shelf may link to public sources, third-party websites, tools, advertisers, or ad partners. Those third parties are responsible for their own content, terms, privacy practices, products, and services.
External references are included to make methods and context easier to inspect. A source link does not mean the third party endorses Toolkit Shelf, and Toolkit Shelf does not control external pages after you leave this site.
Acceptable use
Do not misuse the site, interfere with its operation, attempt to bypass security or rate limits, copy the service in bulk without permission, or use outputs in a way that violates law or the rights of others.
Do not submit sensitive personal data unless it is necessary to reproduce a public site issue. Calculator examples should be treated as estimates, not as a place to store private account numbers, passwords, identification numbers, medical records, or confidential documents.
Contact and acceptance
Use of Toolkit Shelf means you accept these terms. For terms or correction questions, contact hello@toolkitshelf.com.
Continued use after changes means you accept the updated terms. If a page, tool, template, guide, or external link is corrected, that update does not create a duty to preserve older versions or notify every prior visitor.
