Terms of Use
By using Numlu, you agree that calculator results are informational estimates, depend on your inputs and assumptions, and must be checked before important decisions.
Acceptance of these Terms
These Terms govern your access to and use of Numlu. By using the website, calculators, category pages, About page, FAQ, feedback form, or related resources, you agree to these Terms. If you do not agree, do not use Numlu.
What Numlu is
Numlu is a browser-based practical calculator suite for everyday estimates, including home projects, materials, cleaning, energy use, pets, travel, money planning, advertising, tech, crypto mining, and adult calorie estimates. Numlu is designed to show assumptions clearly and help users make rough planning calculations without account friction.
Informational estimates only
Calculator results on Numlu are informational estimates only. Results depend on the numbers you enter, the assumptions you choose, the defaults shown on the page, and the limits of the calculation method. Numlu does not guarantee that any result is complete, current, exact, suitable for your location, or appropriate for your specific situation.
No professional advice
Numlu does not provide financial, medical, veterinary, legal, contractor, tax, investment, insurance, engineering, construction, nutrition, safety, or other professional advice. Calculators are planning tools, not a substitute for qualified professionals, official quotes, product labels, local codes, medical guidance, veterinary guidance, tax rules, or legal requirements.
Your responsibility for inputs
You are responsible for the information, assumptions, units, prices, rates, dimensions, dates, and local conditions you enter into the calculators. You are also responsible for checking whether defaults are reasonable for your country, city, property, pet, body, budget, supplier, lender, utility provider, ad account, network, hardware, or other real-world context.
High-impact decisions
Do not rely on Numlu as the only basis for high-impact decisions. For decisions involving health, pets, major purchases, loans, housing, taxes, construction, roof work, electrical work, legal deadlines, retirement planning, investments, crypto mining profitability, or significant financial risk, check the calculation independently and consult a qualified professional where appropriate.
Home, garden, and contractor estimates
Home, garden, paint, tile, mulch, roof, cleaning, and energy calculators provide rough planning estimates. Actual needs and costs may vary because of waste, product coverage, labor rates, local codes, material quality, surface condition, access, complexity, taxes, delivery, contractor minimums, weather, measurement errors, and other site-specific factors.
Money and planning calculators
Mortgage, car loan, retirement, wedding budget, vacation budget, rent-versus-buy, PPC, and similar money calculators are simplified planning tools. They may not include every fee, tax, risk, rule, market change, inflation effect, lender requirement, investment risk, currency issue, or personal financial factor that could affect a real decision.
Health, fitness, and pet calculators
TDEE, daily calories, dog food, cat food, and similar calculators use simplified formulas and assumptions. They are not medical, nutrition, or veterinary advice. Individual needs can vary based on health, age, medication, pregnancy, growth, breed, body condition, activity, illness, and other factors. Consult a qualified medical or veterinary professional when needed.
Tech and crypto calculators
Download, upload, electricity, and crypto mining calculators depend heavily on changing inputs such as network overhead, real-world speed, hardware performance, pool fees, difficulty, coin price, block rewards, electricity rates, taxes, equipment failure, and market volatility. Crypto mining results are not investment advice and may become outdated quickly.
Testing and verification
You should verify important results before acting on them. Recheck units, assumptions, formulas, local rates, product labels, supplier quotes, official documents, professional advice, and real-world constraints. Small input errors can create large differences in the final estimate.
Permitted use
You may use Numlu for lawful, legitimate, personal, educational, planning, and business-related estimation purposes. You must use the service in a way that does not interfere with the website, overload infrastructure, misuse forms, violate laws, infringe rights, or mislead others.
Prohibited use
You may not use Numlu to create deceptive claims, fraudulent estimates, unlawful financial promotions, misleading professional advice, spam, abuse, scraping at unreasonable scale, attempts to disrupt the service, or any activity that violates applicable law or the rights of others.
Feedback
If you send feedback, bug reports, calculator ideas, or content corrections, you give Numlu permission to use, reproduce, adapt, and implement that feedback to improve the product without any obligation to compensate you. Do not send confidential information, secrets, or materials you are not authorized to share.
Service availability and changes
Numlu may modify, improve, remove, restrict, suspend, or discontinue any calculator, category, feature, language, explanation, default value, formula, or page at any time. Numlu does not guarantee uninterrupted availability, permanent access, or compatibility with every browser, device, country, workflow, or use case.
Third-party resources
Numlu may link to third-party websites, references, tools, products, services, or resources. Third-party resources are controlled by their own operators, not by Numlu. Numlu is not responsible for their content, accuracy, availability, security, pricing, policies, or practices.
No warranties
To the fullest extent permitted by law, Numlu is provided on an "as is" and "as available" basis, without warranties of any kind. Numlu disclaims warranties of accuracy, completeness, reliability, merchantability, fitness for a particular purpose, non-infringement, availability, security, and uninterrupted operation.
Limitation of liability
To the fullest extent permitted by law, Numlu and its operator will not be liable for indirect, incidental, consequential, special, exemplary, punitive, or similar damages, or for loss of profit, revenue, data, opportunities, savings, goodwill, business, or reputation arising from use of the service or reliance on calculator results.
Your responsibility
You are responsible for how you use Numlu, how you interpret calculator results, what decisions you make, and whether you seek professional advice. You agree not to treat Numlu as a guarantee, quote, diagnosis, prescription, financial recommendation, legal instruction, tax position, contractor bid, or official source.
