Terms of Service

Last updated · 19 June 2026

These terms govern your use of the khtwa app (“the app”, “we”, “us”, “our”). The app is a food-logging tool that uses AI to estimate calories and macronutrients for the foods you describe. By installing or using the app, you agree to these terms.

Short version
  • The app gives you AI-powered calorie estimates — they’re educated guesses, not medical advice.
  • If you subscribe, billing happens through your Apple ID. We never see your payment details.
  • Trials convert to paid subscriptions automatically — cancel before the trial ends to avoid charges.
  • You can cancel a subscription at any time through Apple’s Settings.
  • Delete your account from inside the app whenever you want; your data is removed.

7AI calorie estimates

The app uses a third-party AI provider (see the Privacy Policy) to estimate calories and macronutrients for the foods you describe. These estimates are:

If you have a medical condition, are pregnant or nursing, are recovering from an eating disorder, or have any concern that requires accurate nutritional information, consult a qualified professional.

We may suspend or terminate accounts that violate these rules, with or without prior notice depending on the severity.

11Termination

12Disclaimers

Except where law says otherwise, the app is provided “as is” and “as available”. We do not warrant that the app or the AI estimates will be accurate, uninterrupted, error-free, or fit for any particular purpose. Your use of the app is at your own risk.

13Limitation of liability

To the maximum extent permitted by law, our total liability to you arising out of or relating to the app, whether in contract, tort, or otherwise, is limited to the amount you paid us for the subscription in the 12 months before the event that gave rise to the claim. We are not liable for indirect or consequential losses, including lost data, lost profits, or health outcomes attributed to use or non-use of the AI estimates.

Nothing in these terms limits or excludes liability that cannot be limited or excluded under applicable law, including for death or personal injury caused by our negligence, fraud, or any liability that consumer-protection law in your country does not allow to be waived.

14Governing law and disputes

15Changes to these terms

We may update these terms from time to time. If a change materially affects your rights, we will update the “Last updated” date at the top and, where appropriate, notify you in the app. If you do not agree to the updated terms, you should stop using the app and may delete your account.
