Privacy Policy
This privacy policy explains how Well Balanced Calc ("we", "us", "our") handles information when you visit ukbmicalculator.com.
The short version: We don't collect personal information from you directly. We don't have sign-up, accounts, contact forms, or email capture. Our calculators run entirely in your browser — the numbers you enter are not sent to us or stored on any server.
The longer version covers what cookies and similar technologies are used on the site, mostly by third parties.
Who we are
Well Balanced Calc is a publisher of free UK health calculators and educational content. The site is operated from the United Kingdom. You can contact us at wellbalancedcalc@outlook.com.
What information we collect
Information we collect directly: none
We do not run forms, sign-ups, accounts, email capture, or contact submissions on this site. The figures you enter into the calculators (height, weight, age, etc.) are processed by JavaScript in your browser and are not transmitted to us or stored anywhere on our servers.
Information stored in your browser
The site may store small preferences in your browser's localStorage — such as your chosen unit preference (metric or imperial) or theme — to make repeat visits more convenient. These preferences are not transmitted to us. You can clear them at any time by clearing your browser data.
If you install the site as a Progressive Web App (PWA), some files are cached locally on your device so it can work offline. No personal data is included in this cache.
Information collected by third parties
We use Google AdSense to display advertisements on this site. Google AdSense uses cookies and similar technologies to serve ads, including measuring ad performance and serving personalised advertising based on your previous interactions with websites.
The information collected by Google AdSense is governed by Google's privacy policies, not ours. You can review them here:
You can manage your Google ad preferences (including opting out of personalised advertising) at google.com/settings/ads.
Our legal basis for processing (UK GDPR)
For the limited cookies served by third parties for advertising purposes, the legal basis is your consent. Browser localStorage preferences are set only when you actively interact with the site (your action constitutes consent for that single functional purpose).
Your rights under UK GDPR
You have the right to:
- Access any personal data we hold about you (we don't hold any directly)
- Request correction or deletion of any data (this would apply to AdSense data — manage via your Google account)
- Withdraw consent for cookies at any time (manage via Google ad settings or by clearing your browser data)
- Lodge a complaint with the Information Commissioner's Office (ico.org.uk) if you believe your rights have been infringed
Children
This site is intended for adults aged 18 and over. The NHS BMI thresholds used by our calculators apply to adults — they are not appropriate for children or teenagers. The NHS has a separate BMI healthy weight calculator for children and teenagers. We do not knowingly collect information about minors.
Links to external sites
The site links to external sites including the NHS, Beat (the UK eating disorder charity), and Google. We are not responsible for the privacy practices of these external sites.
Changes to this policy
This policy may be updated periodically. The "Last updated" date at the top of this page reflects when the policy was last changed.

Note on health information: Nothing on this site constitutes medical advice. The calculators provide estimates based on standard formulas (NHS BMI thresholds, Mifflin-St Jeor BMR equation, etc.) and do not account for individual medical conditions. Always speak to a qualified healthcare professional or your GP about concerns relating to your weight, nutrition, or health.
