These Terms of Service ("Terms") govern your use of the Kin iOS application and related services (the "Service"), provided by Kin Health Ltd ("Kin", "we", "us"). By creating an account or using Kin, you agree to these Terms.
Kin is an AI-powered fitness coaching app for iOS. It plans your week, guides your workouts, and adapts your meals through conversation. Kin is not a medical service and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making changes to your exercise, nutrition, or health routine.
You must create an account using Sign in with Apple to use Kin. Authentication sessions are managed through our backend provider, Supabase. You are responsible for maintaining the security of the Apple ID linked to your account and for all activity that occurs under your account. You must be at least 16 years old to use the Service.
To provide the Service, your workouts, nutrition entries, profile information, and coaching conversations are stored on your device and synced to our cloud backend (Supabase) so they can be backed up and restored across your devices. Data is encrypted in transit and at rest. We do not sell your data or use it for advertising. See our Privacy Policy for full details on what we collect, how we use it, and how to delete it.
Kin uses artificial intelligence — including Anthropic's Claude API for coaching responses and OpenAI's Whisper API for voice transcription — to generate coaching suggestions, plans, and insights. These outputs are informational only and should not be treated as professional fitness, medical, or nutritional advice. AI responses may occasionally be inaccurate, incomplete, or unsuitable for your situation; you are responsible for using your own judgment and consulting a qualified professional before acting on them.
You agree not to misuse the Service, attempt to access it through unauthorised means, interfere with its operation, reverse engineer it, or use it for any unlawful purpose. You agree not to upload content that is illegal, infringing, or harmful to others.
The Kin app, its design, and its content (excluding the data you provide) are owned by Kin Health Ltd and protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable licence to use the app for your personal, non-commercial use, subject to these Terms.
We may suspend or terminate your access if you violate these Terms or if we are required to do so by law. You can delete your account at any time from within the app, which will remove your data from our systems as described in the Privacy Policy.
Kin is provided "as is" and "as available" without warranties of any kind, express or implied. To the fullest extent permitted by law, Kin Health Ltd is not liable for any injuries, health issues, loss of data, or indirect, incidental, or consequential damages arising from your use of the Service or reliance on AI-generated recommendations. Nothing in these Terms limits any liability that cannot be excluded under applicable law.
These Terms are governed by the laws of England and Wales. Any disputes will be subject to the exclusive jurisdiction of the courts of England and Wales, except where mandatory consumer-protection laws in your country of residence provide otherwise.
We may update these Terms from time to time. When we make material changes, we will update the "Last updated" date above and, where appropriate, notify you in the app. Continued use of the Service after changes take effect constitutes acceptance of the updated Terms.
