Terms and conditions

By using Free Fasting Calc you agree to these terms. They are meant to be fair and readable rather than exhaustive legalese. If you do not agree with them, please do not use the site.

Information only, not advice

Everything on this site is general information about intermittent fasting. It is not medical, nutritional, or professional advice, and it is not tailored to you. Do not use it to diagnose or treat any condition. Always speak to a qualified professional before making changes that could affect your health. See our medical disclaimer for the full detail.

Everything here is a guide

The calculators, results, times, figures and guides on Free Fasting Calc are a general guide only. They are estimates based on published formulas and averages, not a diagnosis, a prescription or a plan made for you. Consult a medical doctor before you start fasting, change how or when you eat, or set out to lose weight, and before relying on any number from this site, especially if you have a health condition, take any medicine, are pregnant or breastfeeding, or are under 18.

Use of the calculators

Our calculators use published formulas and reasonable assumptions, but they produce estimates, not certainties. Individual results vary. You are responsible for how you use any number the site gives you. We are not liable for decisions you make based on it.

Acceptable use

• You may use the site for your own personal, non-commercial purposes.
• You may not copy, scrape or republish substantial parts of the content without permission.
• You may not attempt to disrupt the site, its security, or its availability.

Intellectual property

The text, design, code and original data on this site belong to Free Fasting Calc unless stated otherwise. You are welcome to link to us and to quote short passages with attribution.

Third-party links

Some pages link to outside websites. We do not control those sites and are not responsible for their content, accuracy or practices. A link is not an endorsement. The site shows no advertising.

No warranty

The site is provided "as is" and "as available." We do our best to keep it accurate and working, but we make no guarantee that it is error-free, complete, or continuously available.

Limitation of liability

To the fullest extent permitted by law, Free Fasting Calc is not liable for any loss or harm arising from your use of, or reliance on, this site. Nothing in these terms limits liability that cannot be limited by law.

Changes

We may update these terms from time to time. Continued use of the site after a change means you accept the revised terms. The "last reviewed" date above shows the current version.
