Terms of Service

Last updated: 18 August 2026

These terms govern your use of the KcalOS mobile app ("KcalOS", "the app"). By using KcalOS you agree to them.

The app

KcalOS is a straightforward calorie and macro tracker. You log what you ate against a built-in food table, and it shows where the day stands and how the week went. KcalOS runs entirely on your device.

KcalOS is not medical advice

KcalOS is a personal tracking tool, not a medical device. It does not diagnose, treat, cure or prevent any condition, and nothing it shows you is medical advice. Talk to a qualified professional before changing your diet, training or medication, particularly if you have a health condition, are pregnant, or are recovering from injury or illness. If you think you have a medical emergency, contact your local emergency services.

Your data is yours

Everything you enter stays on your device. We do not receive it, so we make no claim to it and can neither retrieve nor restore it. Keeping it safe — through your own device backups — is up to you. See the Privacy Policy.

Accuracy

KcalOS calculates from reference data and from what you enter. Reference values are approximations, and what you enter may be estimated. Treat every number as a useful estimate rather than a measurement, and do not rely on KcalOS where precision matters medically.

Availability

KcalOS is provided as is, without warranty of any kind. We may change or discontinue it at any time. Because it runs entirely on your device, an update from us is never required for it to keep working on the version you have installed.

Liability

To the maximum extent permitted by law, thetinyapp and its contributors will not be liable for any loss or damage arising from your use of KcalOS, including any decision made on the basis of what it displays.
