Effective Oct 14, 2026

nutrition.mcbflow.com is a free app made by Matthew Broyer. By using it you agree to these terms.

Use it as you like

You can use the app for personal or work purposes at no cost. Please don't try to disrupt the site or use it to harm others.

Your data is your responsibility

Your data lives in your browser on your device. If you clear your browser data, switch browsers or lose the device, it can be lost. Use Data → Save backup now regularly to keep a copy.

Not medical or nutrition advice

Calorie and macro targets, hydration figures, fasting timers, allergy and diet warnings, and the blood alcohol (BAC) estimate are general estimates for information only. They aren't medical, nutrition or safety advice. Allergy warnings match words in food names and can miss ingredients; always read the label. Never use the BAC estimate to decide whether to drive. Ask a doctor or registered dietitian before changing how you eat, especially if you are pregnant or nursing, have a medical condition, or have a history of disordered eating.

Food data

Nutrition values come from the USDA FoodData Central SR Legacy database (public domain) and the TempoLife food nutrition dataset (CC BY 4.0), plus what you enter yourself. They can differ from your actual food.

No warranty

The app is provided "as is", without warranties of any kind. To the extent the law allows, Matthew Broyer isn't liable for losses arising from using it, including lost data.

Changes

The app and these terms may change. The current terms are always on this page.
