Terms of Use | Body Numbers

These Terms of Use (“Terms”) are an agreement between you and Selanto Apps (“we”, “us”) for the Body Numbers mobile app (published on Google Play as “BMI Calculator: TDEE, Body Fat”, “the app”) and the website bodynumbers.app (“the website”). They also serve as the end user licence agreement for the app. By installing or using either, you agree to these Terms. If you do not agree, do not use them. Our Privacy Policy explains how we handle personal data.

In short

The app and the website calculators both calculate. Neither diagnoses, treats or monitors anything, and neither is medical advice.
It is free. Plus is one optional purchase that removes ads and adds cloud sync.
Do not rely on it for a medical decision. Talk to a doctor or a dietitian.

1. Who we are

Selanto Apps, a sole proprietorship (eenmanszaak) registered in Rotterdam, the Netherlands. KvK 75803097, VAT NL002467486B73. Contact: support@bodynumbers.app.

2. Who may use the app

You must be at least 16, or have the consent of a parent or guardian. An adult may use the growth check on behalf of a child or teenager in their care.

3. What the app and the calculators do, and what they do not do

The app applies published formulas to measurements you enter and shows the result against published reference ranges. It names the formula and the source in each case.

The calculators on the website do the same thing in your browser, from the same formulas, and they are free to use without installing anything. Everything in this section applies to them exactly as it applies to the app. Nothing you type into a calculator on the website is sent anywhere; it is calculated on your own device.

Neither the app nor the calculators on the website:

diagnose, treat, cure or prevent any condition;
provide medical, dietary or clinical advice;
replace a consultation with a qualified health professional;
act as a medical device.

Every figure either of them produces is an estimate. Estimates from a tape measure and a set of scales cannot match a clinical measurement, and both the app and the website say so where it matters. If a result concerns you, or if you are pregnant, unwell, under 18, or managing a condition, speak to a health professional rather than acting on a number from an app.

4. Your licence

We grant you a personal, non exclusive, non transferable licence to use the app on devices you control, for your own use. You may not copy, modify, reverse engineer, resell or redistribute it, except where that restriction is prohibited by law.

5. Free version and Plus

The calculators are free. Plus is a single optional purchase that removes advertising and enables cloud sync between your devices. Prices are shown by Google Play in your own currency at the time of purchase.

Purchases are handled by Google Play. Refunds follow Google Play’s refund policy and any statutory right of withdrawal you have under EU consumer law. We cannot process a refund on Google’s behalf.

6. Your account and your content

An account is optional and exists only to sync your own data between your devices. You are responsible for keeping access to the account you sign in with. The measurements you enter remain yours; we claim no ownership of them and we do not use them to train anything or to target advertising.

7. Availability and changes

We may change, suspend or discontinue any part of the app or the website, and we may update formulas and reference ranges when the published sources they come from are updated. We aim to keep the app working but do not guarantee uninterrupted availability.

8. Warranty

The app and the website are provided “as is” and “as available”, without warranties of any kind so far as the law allows. We do not warrant that a calculation is suitable for any particular purpose, medical or otherwise. Nothing here excludes rights you have as a consumer under Dutch or EU law.

9. Liability

To the extent permitted by law, we are not liable for indirect or consequential loss, or for any decision you take on the basis of a number the app produced. Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for anything that cannot be limited by law. Where liability cannot be excluded, it is limited to the amount you paid us in the twelve months before the claim.

10. Ending the agreement

You may stop using the app at any time by uninstalling it and, if you made an account, deleting it. We may end your access if you breach these Terms.

11. Governing law

Dutch law applies. Disputes go to the competent court in the Netherlands, unless consumer law entitles you to bring a claim where you live.

12. Google Play

The app is distributed through Google Play and your use is also subject to the Google Play Terms of Service. Google is not a party to these Terms and has no responsibility for the app.

13. Changes to these Terms

If these Terms change materially we will update the date above and, where the change is significant, say so in the app.

This is not medical advice. Body Numbers is a calculator. It does not diagnose, treat or monitor any condition, and no number it produces should replace a conversation with a doctor or a dietitian. If a result worries you, or if you are pregnant, unwell, or under eighteen, speak to a health professional.
