Allcals builds free, general-purpose tools — an age calculator, BMI calculator, percentage calculator, currency converter, password generator, QR code generator, word counter, PDF tools, and a random number/name generator. This page exists to be honest about what those tools are good for, and just as importantly, what they're not a substitute for. If you only take one thing from this page, let it be this: our tools give you a quick number or output, not professional advice.
Not medical advice
Our BMI calculator and age calculator produce numbers based on standard, publicly known formulas — they don't evaluate your overall health, take your medical history into account, or replace a conversation with a doctor. BMI in particular is a widely used but genuinely limited measure: it doesn't distinguish between muscle and fat, doesn't account for bone density, pregnancy, age-related changes in body composition, or a dozen other individual factors a clinician would consider. Use the result as a rough starting point at most, never as a diagnosis. If you have questions about your weight, health, or any medical condition, please talk to a qualified healthcare professional — not a website.
Not financial advice
The currency converter pulls live exchange-rate data from a third-party source and displays it for quick reference — planning a trip, estimating a purchase, that kind of everyday use. Exchange rates shift constantly, and the rate you see may differ slightly from the rate you're actually offered by a bank, card network, or currency exchange service, which typically add their own margin or fee. Don't use our converter as the basis for investment decisions, large financial transfers, or contractual pricing. For anything with real financial stakes, check with your bank or a licensed financial advisor and use their quoted rate, not ours.
Not legal advice
Nothing on Allcals, including our Terms & Conditions or Policy pages, should be read as legal advice for your own website or business. We wrote those pages to be transparent about how our own site operates, not as a template guaranteed to meet every jurisdiction's legal requirements. If you're building your own service and need legal documents, it's worth having them reviewed by an actual lawyer.
Security tools come with limits too
Our password generator creates random strings using your browser's cryptographic random number capabilities, which is a solid approach for everyday password needs. That said, a strong password is only one part of good account security — using a password manager, enabling two-factor authentication where available, and avoiding password reuse across sites all matter too. We can't guarantee that any password, however randomly generated, makes an account fully "unhackable," because account security also depends on factors outside our tool, like how a service stores your password on its end.
Accuracy and availability
We test our tools carefully and fix issues as soon as we find them, but we can't promise the site will be error-free, always available, or compatible with every possible browser and device combination on earth. Occasionally, an update on our end or a change in a third-party service (like the exchange-rate API) may cause a temporary hiccup. If a tool seems to be behaving unexpectedly, we genuinely want to know — please tell us through the contact page so we can look into it quickly.
Your responsibility as a user
You're responsible for how you use the output from any of our tools. That includes double-checking results before relying on them for anything important, keeping generated passwords private, and using generated QR codes or documents responsibly and legally. We build tools in good faith to be accurate and useful, but the final judgment on how to use a result is always yours.
Advertising disclosure
Allcals displays ads from third-party advertising networks to keep every tool free and account-free. These ads are not endorsements by Allcals of any product, service, or company shown. We don't control every individual ad creative served by our network in real time, though we do review our partners and act on reports of inappropriate ads — you can flag one through our contact page any time.
External links and data
Where our tools or pages reference external services — such as the exchange-rate data behind the currency converter — we do our best to choose reliable sources, but we don't control those third parties and can't guarantee their uptime or accuracy at every moment. Treat any externally sourced figure as a reference point, not a guarantee.
