Terms of Use

The service

Line by Line, LLC operates Cheetah Run (치타야 달려), which offers guided running and walking plans, workout recording, and optional connections to device health features and external assistants. Features can change during testing and may depend on your device, permissions, connectivity, and location. The Privacy Policy explains data handling.

Use it safely

Training suggestions and estimated pace or distance are general fitness information, not medical advice or a guarantee of results. Choose an effort appropriate for you, pay attention to traffic and surroundings, and stop if you feel unwell. Consult a qualified professional before beginning or changing exercise if you have a health concern. Do not operate the app in a way that distracts you from moving safely.

Your account and content

Keep your credentials secure and provide accurate account information. You are responsible for activity on your account and for the workout and profile information you choose to record. You may use the service only for lawful personal purposes; do not misuse it, attempt unauthorized access, or interfere with other users or the service. Contact info@cheetahrun.xyz if you believe your account has been compromised.

Optional integrations

Apple Health, Apple Music, nearby-device pairing, and any external AI assistant are optional. Their availability and separate terms or policies may apply. An assistant receives only the read-only workout summaries you authorize through the connector; you can revoke that connection in the assistant or on our connector management website. We are not responsible for an external service's independent operation or its handling of information after it receives it.

Availability and changes

We may maintain, update, suspend, or discontinue parts of the service. We try to keep the app reliable, but GPS, pacing, sync, and third-party connections may be unavailable or inaccurate. Keep your own copy of information you need. If we make a material change to these terms, we will update the effective date and provide notice where appropriate.

Responsibility and contact

To the extent permitted by applicable law, the service is provided without a promise that it will be uninterrupted, error-free, or suitable for a particular fitness goal. Nothing in these terms limits rights that cannot legally be excluded, including applicable consumer rights. For support, questions about these terms, or account requests, contact info@cheetahrun.xyz. Apple’s standard licensed application agreement may also apply to an App Store download.
