Health Tools Hub publishes free calculators and educational guides. Our priority tools — ovulation, due date, drug interaction checking, and pill identification — are built around established clinical formulas and publicly available labeling data (for example CDC, ACOG, NIH RxNorm, and FDA DailyMed references cited on individual pages).
Educational articles may be drafted with AI assistance for structure and clarity, then edited for accuracy, tone, and source alignment before publishing. We do not claim to replace a licensed clinician, and we do not invent medical credentials. When a page needs specialist review, we state that clearly rather than implying a fictional “medical team.”
We update high-traffic tools and medication safety guides when guidelines or labeling change. If you spot an error, contact us via the Contact page — corrections take priority over new content volume.
Health Tools Hub is not a healthcare provider. Our tools are designed for educational and informational purposes only and should never replace professional medical advice, diagnosis, or treatment.
Always consult with qualified healthcare professionals before making any medical decisions or changes to your treatment plan. If you have a medical emergency, contact your doctor or emergency services immediately.
While we strive for accuracy, individual results may vary, and our tools may not account for all personal factors that could affect your health calculations.
We don't collect your personal health information. All calculations are performed locally in your web browser, which means your data never leaves your device.
We believe privacy is a fundamental right, especially when it comes to your health data. That's why our tools are designed to work entirely on your device without transmitting any personal information to our servers.
