Disclaimers

General disclaimer

Every tool and guide on Free Tool Arena is provided “as is” for informational and educational purposes. Results are computed from the inputs you supply using published formulas. We make reasonable effort to keep formulas accurate, but do not warrant that results are free from error, nor that they will be suitable for any specific purpose or jurisdiction.

You are solely responsible for decisions you make based on outputs from this site. Nothing on Free Tool Arena creates a professional relationship of any kind between you and us.

Financial, tax & investment disclaimer

Money calculators — loan, mortgage, retirement, tax, investment, FIRE, business finance — return estimates based on the numbers you enter and simplified assumptions. They are not financial, tax, or investment advice. Interest rates, tax brackets, insurance costs, market returns, and personal circumstances all vary in ways a general calculator cannot capture.

For any decision that meaningfully affects your finances — taking a loan, refinancing, structuring a retirement account, filing a tax return, making an investment, or running a business — consult a licensed financial advisor, CPA, or attorney in your jurisdiction before acting. We receive no compensation tied to the outputs you see, and we are not registered as an investment adviser.

Medical & health disclaimer

Health calculators — BMI, BMR, calorie, macronutrient, hydration, heart-rate zone, vitamin D, ovulation, electrolyte, sleep cycle, and related tools — are informational only and do not constitute medical advice. They are not a substitute for diagnosis, treatment, or the judgment of a qualified healthcare provider.

Do not use these tools to self-diagnose, to replace prescribed care, or to make decisions about medication, fertility, pregnancy, or serious symptoms. If you think you might have a medical emergency, call your local emergency number or go to the nearest emergency department immediately.

Legal disclaimer

Document templates — including but not limited to bill of sale, NDA, freelance contract, promissory note, rental application, photo release, liability waiver, and letter of intent — are provided as reference templates only and are not legal advice. Laws, required disclosures, and enforceability vary by state, country, industry, and transaction type.

Before signing, serving, or relying on any document generated from this site, have a licensed attorney in your jurisdiction review it for completeness and compliance with applicable law. Using these templates does not create an attorney-client relationship with us or any contributor to the site.

Estimate disclaimer (home, gaming, misc)

Home-improvement calculators (paint, wallpaper, tile, fertilizer, furniture fit) and gaming calculators (sensitivity, FOV, DPS, loot drop, enchantment XP) return estimates based on standard formulas. Actual results depend on local conditions, product variance, game patches, and inputs outside the tool’s model. Treat outputs as a starting point, not a guarantee.

Data accuracy

Some tools reference published values — tax brackets, contribution limits, conversion constants, published drop rates, or game mechanics. Published values change. We update our data periodically but cannot guarantee that every table reflects current regulation or the latest game patch. Verify critical numbers against an official primary source before acting on them.

AI-generated content

Guides and some explanatory content on Free Tool Arena are drafted with the assistance of AI tools and reviewed by a human editor before publication. AI can be wrong. If a guide contradicts official documentation, follow the official documentation.

Privacy & data handling

Unless specifically noted, tools run entirely in your browser: the values you enter are not transmitted to our servers. Exceptions (anonymous usage analytics, ad serving) are documented on the how it works page and the privacy policy.

Changes to this page

We may update these disclaimers as tools, categories, or applicable law change. The “Updated” date at the top of this page reflects the most recent revision. Continued use of the site constitutes acceptance of the current version.
