By downloading or using IF24, you agree to these terms. If you do not agree, please do not use the app.
IF24 is a free, general wellness and timing tool that helps you time intermittent fasting windows and shows estimated metabolic phases based on typical fasting timing.
IF24 is not a medical device and does not diagnose, treat, or measure anything in your body. The phases and information it shows are estimates for general education only and are not a substitute for professional medical advice.
Fasting is not suitable for everyone - consult a qualified healthcare professional before starting, especially if you are pregnant, nursing, taking medication, have a history of eating disorders, or manage a health condition. You use IF24 at your own risk.
IF24 stores your data locally on your device. You are responsible for your device and any backups. Deleting the app deletes its data.

IF24 is provided "as is", without warranties of any kind. We do not guarantee it will be accurate, uninterrupted, or error-free.
To the maximum extent permitted by law, the developer is not liable for any indirect or consequential damages arising from your use of, or inability to use, IF24.
