hello@freefastingcalculator.com
We aim to reply within a few days. No newsletter, no follow-up marketing, and your address is used only to answer you.
What to include
- Bug reports: the page, the times you entered, what you expected, and what appeared instead. Screenshots help. Because your data lives on your device, we cannot see your session, so details matter.
- Corrections: if any statement on the site is mathematically, factually, or editorially wrong, tell us where. We treat corrections as contributions, and revised pages are dated.
- Feature ideas: tell us the problem before the solution. The best features here (start-time editing, the conflict engine) came from real scheduling problems.
What we cannot help with
We are a calculator site, not a health service. We cannot advise whether fasting or a calorie change is appropriate for you, interpret your ABSI or visceral fat estimate medically, interpret symptoms, or comment on medical conditions and medications. Those questions belong with a qualified healthcare professional. The medical disclaimer explains where the line sits and why we keep it firmly drawn.
Privacy of your message
Email is the only channel where any information leaves your device, and it happens only because you chose to send it. Messages are used solely to respond to you and are not added to any list. The privacy policy covers everything else.
