Frequently asked questions
Common Questions about Ovulation
How does the Ovulation determine results?
The Ovulation relies on peer-reviewed physiological formulas and established medical equations to calculate your personal metrics accurately based on your individual inputs.
Should I use these results as clinical medical advice?
Our Ovulation provides reliable health and wellness estimates for fitness tracking and educational planning. For diagnosis, clinical treatment plans, or severe dietary restrictions, always consult a licensed healthcare professional.
Are my personal health measurements private?
Yes. All metrics and inputs (such as weight, height, or age) are processed strictly in your local browser and are never saved, stored, or transmitted to any third party.
How frequently should I recalculate my metrics?
We recommend recalculating whenever your body weight, activity level, training regimen, or wellness goals shift to maintain accurate targets.
