Terms of Use

No lawyer has read this

These terms were drafted carefully and adversarially, and then not reviewed by anyone qualified to review them. calivue is run by one person, not a company, and a one-time legal review has not happened. We would rather say that plainly than let the formal wording below imply otherwise.

Published 17 August 2026. This is the date the page went live.

Not settled, and named rather than guessed

The limit on liability in section 7 names no figure. Whether a fixed monetary cap is even enforceable against consumers in the EU, the UK and several US states is a question for a lawyer, and inventing an amount would look like an answer.
The dispute-resolution mechanism in section 13 is unnamed — Singapore courts or arbitration in Singapore. The governing law is Singapore either way; it is the forum that is undecided.

Each of these is a real decision that has not been taken. Filling one in with something plausible would read as settled and would be worth less than saying so.

1. Who runs this site, and what accepting these terms means

These Terms of Use ("Terms") govern your access to and use of calivue.com and the tools and content on it (the "Site"). The Site is operated by the operator of calivue.com, an individual based in Singapore who provides it independently and on a personal, non-incorporated basis ("the operator", "we", "us").

By using the Site you agree to these Terms and to our Privacy Policy,Cookies notice and Consumer Health Data Privacy notice, which are part of these Terms. If you do not agree, do not use the Site. You can reach the operator at [email protected].

2. Age

The Site is intended for a general adult audience. By using it you confirm you are at least the age of majority where you live (18 in most places). Between the minimum digital-consent age in your country and the age of majority, use the Site only with a parent or guardian who agrees to these Terms on your behalf.

The Site is not directed to children under 13 and we do not knowingly permit their use of it. If you are a parent or guardian and believe a child under 13 has used it, write to [email protected] and we will take reasonable steps to delete anything we control. Where local law sets a higher minimum age for data-processing consent, that higher age applies.

3. What the Site actually is

calivue provides free, browser-based health and fitness calculators — daily energy needs (TDEE), macronutrients, body-fat percentage, FFMI, running pace, one-rep-max, weight-loss timelines, body recomposition and a multi-metric dashboard.

The calculators run entirely in your web browser using published, population-level formulas. The figures you enter are processed on your own device and kept in your browser's local storage; they are not transmitted to or stored on the operator's servers. That is a genuine protection and it is not absolute: your inputs remain on your device, may be visible to anyone with access to it, and can be affected by your own browser settings, extensions or device security.

⚠️ This on-device handling of your calculator inputs is separate from data that third parties may collect when you visit — see section 9 and our Cookiesnotice.

The outputs are general estimates and informational ranges, not measurements of your actual physiology. They can be inaccurate or unsuitable for you, through estimation error in the formulas themselves and through the accuracy of what you enter. Tools and content may change or be discontinued at any time.

4. Not medical advice

The Site is for general information and education only. It is not medical, nutritional, fitness or other professional advice, and it is not a substitute for a qualified professional.

Using it creates no doctor–patient, dietitian–client, trainer–client or other professional relationship. The tools give estimates and ranges — not prescriptions, diagnoses or treatment plans — and no result tells you what is safe or appropriate for you specifically.

Speak to a qualified healthcare provider before starting, changing or stopping any diet, exercise, weight-management, supplement or medication programme, and before acting on anything here. Never disregard or delay professional advice because of something you read or calculated on this Site. In an emergency, call your local emergency number.

5. Your own risk

To the fullest extent the law permits, you use the Site and anything you get from itat your own risk. You are responsible for decisions you make and actions you take on the basis of it — diet, nutrition, exercise, training load, body weight and other health or lifestyle matters — and for judging whether a result suits you, ideally with a professional. Physical activity and dietary change carry inherent risks, including injury and adverse health effects. Nothing here limits liability that cannot be limited, or reduces consumer rights you have under the mandatory law of your home country.

6. "As is" — no warranties

To the fullest extent the law permits, the Site and all content and results are provided"as is" and "as available", without warranties of any kind, express, implied or statutory. We disclaim all warranties including merchantability, satisfactory quality, fitness for a particular purpose, accuracy, reliability and non-infringement.

We do not warrant that the Site or any result will be accurate, complete, current, error-free, reliable, uninterrupted, secure or available, or that any estimate is correct for your circumstances. Some places do not allow these exclusions; there they apply only to the minimum extent the law permits, and any non-excludable statutory guarantee remains in force.

7. Limitation of liability

To the maximum extent the law permits, the operator will not be liable for indirect, incidental, special, consequential, exemplary or punitive damages, or for loss of profits, data, goodwill or health outcomes, arising from your use of or inability to use the Site — whether in contract, tort (including negligence), strict liability or otherwise, and even if advised of the possibility.

⏳ No monetary cap is stated here, and that is an open point rather than an omission.Whether a fixed cap is enforceable at all against consumers in the EU, the UK and several US states is a question for a lawyer, and naming a figure before that is answered would read as a decision that has not been taken.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited — including liability for death or personal injury caused by negligence, for fraud, and any remedy your home country's mandatory consumer law does not permit to be removed. You may have rights these Terms cannot override.

The Site is provided free of charge, and to the extent the law permits these limits are intended as a reasonable allocation of risk and are part of why it can be provided at all.

8. Indemnity

To the fullest extent the law permits, you agree to indemnify the operator against third-party claims, liabilities, damages, losses and reasonable expenses arising from yourmisuse of the Site, your breach of these Terms, or your violation of any law or third-party right. This does not apply where a claim arises from the operator's own conduct, and it applies only so far as your home country's mandatory law allows — in parts of the EU and UK a consumer indemnity of this kind may not be enforceable.

9. Advertising and third-party links

The Site is intended to be supported by advertising served through Google AdSense, and may link to third-party sites the operator does not control.Ads are not switched on yet — no ad code is served today, which you can confirm from the page source.

When they are switched on, Google and its partners may use cookies, your IP address, device identifiers and similar technologies to serve and measure ads. Unlike the calculator inputs in section 3, that ad-related data is collected by those third parties rather than staying on your device. In the EEA, UK and Switzerland this happens behind a consent prompt. Full detail is in Cookies and Privacy.

The operator does not control or endorse third-party content, ads, products, services or their privacy practices. Your dealings with any third party are between you and them, under their terms.

10. Intellectual property

The Site's original content, features, design, text and software are owned by the operator or its licensors. You have a limited, personal, non-exclusive, non-transferable, revocable licence to use the Site for your own personal, non-commercial purposes.

You may not copy, republish, distribute, modify, sell or exploit any part of the Site or its code without written permission, except as the law expressly allows. ★ The underlying scientific formulas are drawn from published sources and are not claimed as ours — this section covers our particular implementation and presentation of them, not the mathematics.

11. Acceptable use

You agree not to:

use the Site in breach of any law, or of anyone else's rights;
rely on it for a purpose it is not intended for, or hold it out to others as professional advice;
disrupt, damage, overload or impair the Site, or introduce malicious code;
attempt to gain unauthorised access to, probe or test the Site or related systems;
reverse-engineer any part of it, except to the limited extent the law expressly permits;
use bots, scrapers or crawlers in a way that imposes an unreasonable load or evades a restriction; or
interfere with any advertising, consent, security or measurement mechanism.

We may suspend access at any time if we reasonably believe you have broken these Terms. As the Site is free and needs no account, these Terms otherwise continue to apply to your past use, and sections 4–10 and 12 survive.

12. Changes

We may change these Terms. When we do, the published date above changes and the updated Terms appear on this page. Changes take effect when posted, except where the law requires notice or fresh consent. Continuing to use the Site after that means you accept them. If you do not agree, stop using the Site.

13. Governing law and disputes

These Terms, and any dispute arising out of them or the Site, are governed by thelaws of Singapore, without regard to conflict-of-laws rules. That choice doesnot deprive you of the protection of mandatory consumer rules of the country you live in, where those apply and cannot be overridden by agreement.

⏳ The forum for a dispute — Singapore courts, or arbitration in Singapore — is not settled, and is named here rather than guessed. It needs a lawyer's view on enforceability against consumers abroad, including any limits on class-action waivers. The governing law above is not affected by that gap.

If any provision is held invalid, it is limited or removed to the minimum extent necessary and the rest stands. A failure to enforce a provision is not a waiver of it.
