Do all health tools work offline?
Yes. The BMI Calculator, Calorie Calculator, Macro Calculator, Sleep Calculator, Body Fat Calculator, and Ideal Weight Calculator run entirely in your browser. Once the page has loaded, no connection to our servers is needed for calculations.
Can I report a wrong result or suggest a feature?
Please do — it helps us improve. Include the tool name, the inputs you entered, and the result you expected. We usually fix confirmed issues within a few days.
Is my data shared when I use the contact form?
No. Your message is used only to answer your inquiry and is never shared with third parties. There is no newsletter and no spam — you hear from us only when we reply.
