Your data, your privacy
Learn how Real BMI protects your input data and keeps all calculations private and secure.
At Real BMI, we take your privacy seriously. Our BMI, BMR, TDEE, and body composition calculators are designed so that your personal inputs remain on your device and never get stored on our servers.
We do not collect, store, or share your height, weight, age, or health inputs. The calculations are performed locally in your browser, making Real BMI a privacy-first health tool.
Only anonymous usage patterns may be collected for product improvement. This helps us refine calculator accuracy, improve user experience, and optimize the site without compromising your personal health information.
We do not sell or trade your data. Any analytics we use are aggregated and anonymized. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet.
Users may opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.
We strive to keep Real BMI secure with modern web practices. If you have questions about privacy or security, contact us and we will respond quickly.
