These Terms form an agreement between you and GRITFIT.AI LIMITED (company number 17066827), registered at 71–75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom ("GRITFIT", "we", "us").
1. Who may use GRITFIT
You must be at least 16 and located in the United Kingdom, one of the 50 United States or District of Columbia, Australia or New Zealand. You must give accurate account and age-verification information. We may suspend an account if we cannot verify eligibility.
If you are 16 or 17, safeguarded optional categories remain locked until both you and a parent, legal guardian or another person with parental responsibility separately approve that category. Those categories include optional health processing, connected health, precise route storage, Progress Vault photos, Hidden Folder photos or videos and paid subscriptions. Failed-unlock security photography is adult-only.
2. The service
GRITFIT is consumer fitness software. It can create and adapt training, provide workout execution tools, record training and offer conversational guidance through GRITFIT Coach. Features vary by platform, device, membership, beta status and availability.
GRITFIT does not provide medical care, diagnosis or treatment and is not a substitute for a doctor, physiotherapist, emergency service or qualified in-person coach. The detailed Health and Training Disclaimer forms part of these Terms, but any consent to process health information is requested separately.
3. Your account
Keep your login and device secure. Do not share your account, bypass access controls or use another person’s credentials. Tell support@gritfit-ai.com promptly if you believe your account has been compromised. You remain responsible for deciding whether a workout is suitable and for recording information accurately.
4. Coach and automated output
Coach uses protected external language-model processing within controlled GRITFIT server processes. Coach is AI-generated, not a human coach, doctor or clinician. Output may be incomplete, unsuitable or wrong. Additional rules and validations are used, but they do not eliminate risk. Do not use Coach for emergencies, medical decisions or instructions to train through alarming symptoms. See the AI Transparency Notice.
5. Safety
Use appropriate equipment, surroundings, technique and supervision. Stop if you experience chest pain, fainting, severe breathlessness, a new neurological symptom, sharp or worsening pain, or another alarming symptom. Contact the emergency service for your location when necessary.
Information about an injury or limitation may influence suggestions, but it does not make GRITFIT a clinical assessment service. You must seek qualified advice where appropriate.
6. Your content
You retain ownership of information and media you upload. You grant GRITFIT a limited licence to host, copy, transform and process that content only to operate, secure, support and improve the service as described in the Privacy Notice and your choices. You must have the right to upload it and must not upload another person’s private, unlawful or exploitative content.
Progress photos and Hidden Folder media are private account features, not end-to-end encrypted storage. Users aged 16 or 17 require category-specific teen agreement and guardian authorisation before these features unlock. Do not use GRITFIT as the only copy of important material.
Adults can separately opt into an off-by-default failed-unlock security-photo feature. It shows a camera-active indication before capturing after repeated incorrect Hidden Folder GRITFIT PIN attempts, does not trigger from biometric failures, stores the image and timestamp in the owner's Hidden Folder, and can be disabled with its security photos deleted. Platform policy may require the feature to remain unavailable.
7. Acceptable use
You must not misuse the service, probe or defeat security controls, scrape it at scale, introduce malware, reverse engineer protected components except where law permits, impersonate others, generate dangerous instructions, or use it to harm, harass or exploit anyone. The Acceptable Use and Safety Rules provide more detail.
8. Beta availability and changes
Beta features may change, be interrupted, lose data or be withdrawn. We may impose usage limits and may change or discontinue non-paid beta functionality. We will not use this clause to remove rights that cannot lawfully be excluded. The Private Beta Terms apply while an account is in the beta.
9. Subscriptions
GRITFIT is not currently making a public paid offer. Designated beta builds may expose Apple or Google subscription products for sandbox, licence-test or TestFlight testing. A store checkout, when enabled, controls the product, price, billing period, renewal and any trial. Users aged 16 or 17 require the paid-subscription guardian category before the app or backend allows purchase. See the Subscription Terms.
10. Intellectual property
GRITFIT software, branding, designs, workout systems and content supplied by us are owned by or licensed to GRITFIT. These Terms give you a personal, limited, revocable, non-transferable right to use the service for lawful personal fitness purposes.
11. Suspension and termination
You may stop using GRITFIT and request account deletion. We may restrict or suspend access to protect users, investigate abuse, comply with law or respond to a material breach. Where reasonably possible, we will explain the reason and provide a way to contact us.
12. Liability and consumer rights
Nothing in these Terms excludes liability that law does not allow us to exclude, including liability for fraud, fraudulent misrepresentation, or death or personal injury caused by negligence where applicable. Nothing limits mandatory consumer guarantees or statutory remedies.
To the extent permitted by law, GRITFIT is provided without a promise that it will always be available or that every output will be accurate. We are not responsible for loss caused by ignoring clear safety information, using the service unlawfully, or relying on it for a purpose it is not designed to serve.
13. Governing terms
These Terms are governed by the law of England and Wales, but you retain mandatory protections and court rights in your place of residence. Regional supplements prevail over these Terms where they provide a mandatory local right. If one provision is unenforceable, the remainder continues.
14. Changes and contact
We may update these Terms. If a change materially affects your rights, we will give appropriate notice and request renewed acceptance where required before continued use. Contact support@gritfit-ai.com.
