Short version: Fantisfy publishes general health information and free estimate tools. We are not your doctor, nothing here is a diagnosis, and no article or calculator on this site should replace a conversation with a qualified healthcare professional.
The longer version is below, because on health topics the details actually matter.
1. This Is Information, Not Medical Advice
Everything published on Fantisfy, including articles, guides, calculators, charts, and answers to reader questions, is provided for general informational and educational purposes only.
It is not medical advice. It is not a diagnosis. It is not a treatment plan or a prescription. It is not a substitute for professional medical care from someone who can examine you, review your history, and take responsibility for your care.
Always seek the advice of your physician, dentist, pharmacist, or another qualified health provider with any question you have about a medical condition, a medication, a symptom, or a treatment option. Never disregard professional medical advice, or delay getting it, because of something you read here.
2. In an Emergency, Stop Reading
If you think you may be having a medical emergency, call your local emergency number or go to the nearest emergency room immediately. In the United States, call 911.
If you are in crisis or thinking about harming yourself, in the US you can call or text 988 to reach the Suicide and Crisis Lifeline, 24 hours a day. Please do not use a website to decide whether your situation is serious enough. Reach out.
3. No Doctor and Patient Relationship
Reading Fantisfy, using our calculators, subscribing to our newsletter, or contacting us does not create a doctor and patient relationship, or any other kind of professional and client relationship, between you and Fantisfy or any of its writers.
We cannot and do not provide individual medical guidance. If you email us describing symptoms, we will not diagnose you. We will point you toward seeing a professional, because that is the honest answer.
4. About Our Calculators and Tools
Our free tools include estimators for water intake, protein needs, max heart rate and training zones, lean body mass, waist-to-height ratio, sleep debt, caffeine timing, fasting windows, walking calories, steps to miles, period timing, and the typical cost of dental treatments.
Please understand what these are and are not:
- They are estimates. Each one applies a published, general-population formula to the numbers you enter. They are not measurements of your body and not clinical assessments.
- They do not know your context. They cannot account for your medical history, medications, pregnancy, kidney or heart conditions, eating disorder history, injuries, or anything else specific to you. Any of these can change what is actually appropriate for you, sometimes dramatically.
- Cost tools are ballpark figures. Price ranges for dental implants, aligners, or whitening vary widely by provider, city, complexity, and insurance. Treat our output as a rough expectation for a conversation, not a quote.
- Period and fertility timing is not contraception. Our period calculator estimates dates from cycle averages. Do not use it as a method of birth control or as a fertility treatment guide.
- Nothing is stored. Calculations run in your browser. We do not save the health details you type in. See our privacy policy.
If a tool gives you a result that surprises or worries you, that is a good reason to talk to a professional, not a reason to act on the number alone.
5. Accuracy, and Where We Fall Short
We research our content, cite sources, and try to represent the evidence fairly, including saying when it is mixed or thin. We also update articles when guidance changes.
Even so, we make no warranty that everything on this site is complete, current, or free of error. Health science moves. Articles can go stale between reviews. Human mistakes happen. Content is provided on an “as is” basis, without warranties of any kind, express or implied.
If you spot something wrong, please tell us at fantisfy@gmail.com. We would rather correct an error than defend it, and we will credit corrections where it makes sense to.
6. Your Decisions Are Your Own
To the fullest extent permitted by law, Fantisfy and its writers accept no liability for any loss, injury, or damage arising from your use of this website, its content, or its tools, or from any decision you make based on them.
You use this site voluntarily, and you are responsible for what you choose to do with the information on it.
7. Links to Other Sites
We link out to research papers, health authorities, and other resources when they support what we are saying. Those sites are not under our control. We are not responsible for their content, their accuracy, or their privacy practices, and a link is not an endorsement of everything a site publishes.
8. Advertising and Affiliate Disclosure
Fantisfy is free to read, and we may earn revenue to keep it that way. That can include display advertising served by third-party networks, and affiliate links where we earn a commission if you buy through them at no extra cost to you.
Two commitments on this. First, commercial relationships never determine our editorial conclusions. If something is not worth it, we say so. Second, we do not accept payment to present a product as a treatment or a cure.
Third-party advertisers may use cookies to serve relevant ads. You can read how that works, and how to control it, in our privacy policy.
9. Not a Substitute for Local Guidance
Our content is written primarily for a United States audience and uses imperial units. Medication availability, treatment norms, dental pricing, insurance rules, and health guidelines differ by country and sometimes by state. Check what applies where you live.
10. Changes to This Disclaimer
We may update this disclaimer as the site grows or as our obligations change. The date at the top always reflects the current version. Continuing to use Fantisfy after an update means you accept the revised terms.
