Privacy Policy

Last updated · 17 June 2026

This policy explains how khtwa (“we”, “us”, “our”) handles your information. The app is designed to collect as little data as possible while still doing its job: helping you log what you eat and estimate calories.

Short version
  • We only collect what we need to track your food and weight.
  • Your data lives on a third-party hosting platform that we control and manage on your behalf.
  • The text you type to log a meal is sent to an AI provider for calorie estimation, then discarded.
  • No ads, no analytics, no tracking, no third-party SDKs you don’t see in this policy.
  • You can delete your account and all your data from inside the app at any time.
