Terms of use

Last updated November 13, 2026

These terms cover your use of the KinFit app, its website and its connection to AI assistants (together, "KinFit"). KinFit is run by 17242654 Canada Inc. in Ontario, Canada ("we"). By using KinFit you agree to these terms.

Not medical advice

KinFit gives general fitness and nutrition information. It is not medical advice and does not diagnose, treat or prevent any condition. Plans are written by the AI assistant you choose, and AI can make mistakes. Check with your doctor before starting a new training or diet plan, especially if you have an injury, a medical condition, take regular medicine or are pregnant. Stop and get help if anything hurts or feels wrong. You train and eat at your own risk.

Your account

You must be at least 16 to use KinFit. Keep your sign-in details to yourself; you are responsible for what happens in your account. Give accurate information about yourself, because your plan depends on it.

Your AI assistant

You choose which assistant to connect, such as Claude, ChatGPT, Gemini or Grok. That assistant is a separate service with its own terms and privacy policy, and we do not control what it writes. You can disconnect it at any time in the app. Everything it saves to KinFit is checked before it is stored, but you are the one who decides whether to follow a plan.

Your content

What you log and the plans saved to your account belong to you. You let us store and process them only to run KinFit for you, as described in the privacy policy. You can delete your account and its data at any time.

Fair use

Do not misuse KinFit: no trying to reach other people's data, break or overload the service, get around its limits, or use it for anything unlawful. We may suspend an account that does.

Exercise videos

Exercise videos are played from YouTube and belong to their creators. Using them is subject to YouTube's terms.

Changes and availability

We keep improving KinFit, so features may change or be removed. We try to keep it running but cannot promise it will always be available or free of errors. If we change these terms, we will post the new version here with a new date.

Limits on our liability

KinFit is provided as is. To the extent the law allows, we are not liable for injury, loss or damage from following a plan or using KinFit, or for indirect or consequential losses. Nothing here removes rights you have under consumer law where you live.

Law

These terms are governed by the laws of Ontario and of Canada that apply there.
