Privacy Policy
Last updated: 31 May 2026
1. Introduction
This Privacy Policy explains how InFast ("InFast", "we", "us", "the App") collects and uses data when you use our guided-fasting application. We collect only the information needed to provide core functionality, maintain stability, improve the overall user experience, and understand how people discover InFast.
InFast does not require an account to use. Your fasting schedules, fasting history, weight entries, and goals are stored only on your device. We do not include your weight figures or other personal health values in the analytics events we collect, and we do not sync this data to an account, backup, or server we control. The data described below is limited to anonymous analytics, diagnostics, and subscription information.
