LeanFifty is a free, non-commercial personal/hobby project that helps people track calories and protein. By using it you agree to these terms.
The calorie and protein targets are general estimates (Mifflin-St Jeor formula) for information only. They are not medical, nutritional, or professional advice. Consult a qualified doctor or dietitian before changing your diet, especially if you have a health condition, are pregnant, or take medication.
Recipes, nutrition values, meal plans, and the photo food-recognition are generated or estimated by AI and may be inaccurate, incomplete, or wrong. Always verify before relying on them.
"Vegan"/"Vegetarian" labels and ingredient lists are best-effort and may contain errors. If you have allergies or dietary restrictions, check the actual ingredients yourself before eating.
Use the app for your own personal tracking. Don't scrape, abuse, or attempt to disrupt it. Recipes you submit must be your own content that you have the right to share.
Sign-in is via Google. You're responsible for activity on your account.
The app is provided "as is", without warranties of any kind, express or implied.
To the maximum extent permitted by law, the maintainer is not liable for any loss or harm arising from use of, or reliance on, the app or its estimates and AI-generated content.
The app and these terms may change at any time.
