Terms of Service

Last updated: April 2026

Acceptance of terms

By downloading, installing, or using LivaFast(the “App”), you agree to be bound by these Terms of Service (“Terms”). If you do not agree, do not use the App. The App is published by LivaFast Inc.(“we,” “us,” “our”).

Description of service

LivaFast is an iOS application designed to help individuals track fasting windows, log liver-related biomarkers (ALT, AST, GGT, FIB-4), and receive on-device AI coaching for metabolic liver health. The App is available for iOS 26+ and watchOS 11+.

Not medical advice

LivaFast is not a medical device and does not diagnose, treat, or cure any condition. Always consult a qualified healthcare provider before making changes to your diet, fasting routine, or medication.

The Liver Progress Score (LPS), fasting insights, and LiVA coaching suggestions are informational tools. They are not clinical assessments, diagnoses, or treatment recommendations. Always consult a qualified healthcare provider — particularly a hepatologist or gastroenterologist — before making decisions about your liver health.

Purchase and pricing

The App is a one-time purchase of $39.99 (USD) through the Apple App Store. There are no subscriptions, in-app purchases, or recurring charges. Apple Family Sharing is supported for up to 6 family members.

All purchases are processed by Apple and subject to Apple’s App Store terms, including their refund policy. We do not process payments directly.
