Terms of service

Last updated November 12, 2026. Draft for the private beta.

The service

KroiOS is a training app in a private beta. Features may change, break or be removed, and data may occasionally need to be reset.

Not medical advice

KroiOS gives general training guidance. It is not medical advice and does not diagnose or treat injuries or conditions. Talk to a doctor or physiotherapist before starting a program, and about any pain or injury. Stop any exercise that causes pain. You train at your own risk.

Your account

Keep your sign-in secure and give accurate information. You are responsible for activity on your account.

Your data

Your data stays yours. You let us use it to provide the service as described in the privacy policy. You can export it and delete your account.

Connected services

Connecting Oura or Apple Health is optional and also subject to their own terms. We are not responsible for those services.

Acceptable use

Don't misuse the service, try to access other people's data, or interfere with how it runs.

Liability

The service is provided as is, without warranties. To the extent the law allows, we are not liable for injuries, lost data or other damages from using it.

Changes and ending

We may update these terms (the date above changes) or end the beta. You can stop using KroiOS at any time.
